My best guess is that the upload and/or insert and/or compare takes
'too long' and the browser and/or your session is timing out.

Unless all this upload and compare is done in a matter of a couple
seconds, you'd be better off to do the upload, and then have a
"status" page to check back later for the comparison.

If you want to drop support of dynamic images for the zillion AOHell
users because it is uneconomical, that's fine with me.

Well since I did this to work around bugs in various versions of IE
back in the day, it's not just browser-wannabes.

"Fred's Warehouse Browser" was merely the extreme example to avoid the
argument of supporting (or not) what some would consider legacy
browsers.

Bottom line, though, is that if you want the IMG to be always up to
date in ALL browsers, reliably, there is no combination of header()
calls that will work.

The random IMG tag will work reliably, unless the browser is so
badly-broken that it's not even "alpha" software yet.

Note that you would *ONLY* do this for dynamic images which,
presumably, you *WANT* to dedicate the bandwidth/$$$ for the
up-to-date image to be available to the user.

You could, of course, use a time-stamp cache mechanism where you would
use the unique IMG URL of the most recently generated image, and then
your bandwidth could be one (cached) image per minute, or 5 minutes,
or hour or whatever is suitable.

My main point is that if you do NOT want the image cached, then don't
use the same URL for it, and using header() is simply not going to
work, no matter what combination of header() calls you use.

PS
Please, all, for the love of [deity], don't reply to me with a post
claiming that you use header(x);header(y);header(z) and it "works"
unless you have tested, as I have, in every minor release version of
every browser since IE/NS 3.0, as well as the AT&T re-branded IE 4.7
browser (used by AT&T employees) which does not behave the same as the
exact same version of IE 4.7 that is on the open market...
Been there; done that.

I *believe* the current state of the art on this stands as follows:

GD now supports animated GIFs.
PHP does not (yet) have the GD functions in its GD extension.

So your two simplest options I can see are:

#1. Add the GD animated GIF functions to PHP source and submit it as a
patch.

#2. Create the individual frames in GD, and then use
http://php.net/exec with ImageMagick (or similar) to composit the
individual frames into a single animated GIF.

I haven't actually LOOKED at the GD section of the manual in a while,
so maybe the animation functions have been added...

It's arguable that using a highly popular framework makes your attack
surface larger.

The Bad Guys would MUCH rather have a hack that they can use to attack
a million sites than one that would only work on one of my stupid
little sites that nobody visits and nobody cares about anyway.

> Is there anything out there like that?

You may want to look at Drupal, Cake, PHPNuke, Smarty, ...

The list is endless, really, with a dizzying array of different features.

And you're not going to get any kind of concensus on this one at this
time, and probably not for the forseeable future.

I know many frameworks that exist, I have seen their code and their
documentation, which is more than enough to reach the conclusion that
using the frameworks that exist is not better that using my own
solutions for my own purposes.

I do not need to jump off a building to realize that it would not be a
better idea than using the stairs or the elevator.

It is a bit exaggerated metaphor because I really do not think that
using somebody else's PHP code is like suicide. I just think that using
my own code that is proven and has matured during many years, is much
better for my own purposes than using something existing frameworks.

Having standard API specifications does not prevent anybody to choose
using solutions based on APIs that do not conform to any standard
specifications.

Furthermore I do not think that seem to understand the difference
between an API specification and API implementation. J2EE is an API
specification with many implementations from different vendors: Sun,
IBM, Oracle, BEA, JBoss (this last one is Open Source). You can choose
the implementation you want.

There is plenty of choice to anybody. If you want to use a J2EE
implementation to build your applications, otherwise you are free to use
something else.

I am not talking of implementation methodologies, I am talking about API
specifications. The same API specification can be implement with
different methodologies. As long as they pass API compliance tests, that
is all right.

You totally misunderstand me. When I talk about lack of organization in
the PHP community, I am not saying that the people that implement
frameworks are disorganized. What I am saying is that there is no
organized effort to site together and produce standard API
specifications for the frameworks, like there is the Java community.

I am pro-choice, so having choice is a good thing.

That is not my point. My point is that for instance, when you want to
develop PHP database applications, there is no consense on which API
would be the best to use.

The reason why it is a bad thing is that that when people develop PHP
components that need to access to a database, they will hardly support
more than one database API. Whoever uses other database API may not
benefit from those components.

Let me give a concrete example, I have developed some plug-ins for this
forms class that provide auto-complete support to text inputs and linked
select inputs. They use AJAX to retrieve auto-complete text options and
switch the linked select options from a database on the server.

http://www.phpclasses.org/formsgeneration

It is not viable for me to support all database API that exist for PHP.
Actually it is already a big deal that that I could find time to support
MySQL (directly) or a bunch of other databases using Metabase or
PEAR::MDB2 API.

The developers that use other database API cannot benefit from these
auto-complete and linked select plug-ins, unless they develop variants
of the plugins that support the database API that they prefer, but then
they would be on their own as I would not be able to provide support to
them.

Everybody looses opportunities with this. If there was a standard API
database specification for PHP like PDBC similar to JDBC, there would be
no such problem.

You totally distorting what I said.

a. I said my packages are preferred for my own purposes. I did not say
that my packages are prefferrable for other peoples purposes.

b. I did not say Java is better, otherwise I would use Java, which I
don't. I said that in the Java world the is something called Java
Community Process (JCP) which is a body made from people from the Java
community that is responsible for specifying Java APIs. That would be a
good thing to adopt by the PHP community if it were more organized and
cooperative.

I am sorry you felt the need to be disrespectful and resort to personal
insult, even more in public. It is a clear sign that you run out of
serious arguments and do not have anything worthy to add to the discussion.

But I cannot be bothered if your parents did not give you proper
education. You do not deserve further of my attention. Do not bother to
reply. I will not follow up.

I admit I have not expressed myself clearly. What I meant is not that
people should be disallowed to implement alternative APIs, but rather
that they should not feel the need to do it.

In the Java world, JDBC is the de facto standard because Java developers
do not feel the need to develop other database APIs. That happens
because JDBC is a standard API defined by several players from the SQL
database world that sit together and defined a consensual API specification.

In the PHP world there is no such organization nor the vision of the
benefits of cooperating to define such standards. I already gave an
example of the benefits of having such standard API specifications in
the other comment to Rob.

Aaaah, so you are trully a genius to be able to at a glance of

That depends, if there was one of those great big inflated stunt things
at the bottom, I'd certainly give it a go. But then I generally look
before I leap.

You are fully entitle to that stance, I commend it, but then to move
forward and write a commentary about recommended PHP frameworks in which
you make no recommendation... well that just doesn't sit right. The
utility of many things in life is rarely realized until it has been used
in practice. many people have said they don't like Linux, they've read
the books, they've looked under the hood. But unless they give it a good
go, I just can't take their opinion seriously.

It's seems people have chosen... and they've chosen not to bother with
some kind of standard API. That's not to say one won't emerge, but it
doesn't seem like it's important at this time.

Allow me to rephrase. You presume that any API specification would be
optimal. Because if it wasn't optimal, no matter how organized you think
the community might be, a new API WILL emerge.

No I understood you perfectly fine. I understood that you were speaking

There's this thing called an adapter pattern. Great for retrofitting
other people's code without actually modifying it.

There are two ways for standards to come about. They can be hand picked
or they can emerge. Hand picked requires the "community organization" of
which you speak. Emergent standards requires the popular vote. I'm in
the latter camp, let the developers speak to the merits of any given
standard. And if they don't speak, it's probably not important.

I think you may be missing the point. Many people probably don't feel
the "need" to create an alternative API, they may just feel the desire
to do so. It's a great way to practice your skills, and in the end, you
have a nice API that meets your needs.

Almost all APIs can be wrapped when necessary. Hell, the PHP engine is
in many cases just a wrapper around a C API.

This is partially true because Java is owned and managed by SUN, and SUN
is all about developing API's, both to ensure that it's own later work
will work, and because it meant a better way for people to interface.
And while you use JDBC as an example of something that won out, it isn't
the only way to interface with Databases through Java, nor was it always
accepted as the best way. In fact there is still a lot of discussion
about other methods, and follow ons to JDBC. Also, JDBC doesn't
eliminate the database specific variations entirely. You still have to
deal with slight variances between specific databases, or incomplete
JDBC implementations or JDBC implementations that provide additional
functionality that isn't part of the spec.

By the same token Pear_DB, and the follow ons were much like the early
versino of JDBC. As is PDO in a lot of ways. The majority of the
database specifics have been abstracted out and a general interface has
emerged. Unlike in Java though, the PDO and Pear_(M)DB(2) families
haven't settled yet(nor did JDBC overnight) but they are being developed
by the community. And many people DO recognize the advantage of
standards and basic API's and are working to develop exactly those kinds
of things in their frameworks. Solar, as a simple example I have some
experience with, is spending a lot of time thinking about how components
fit togethor, how to allow for a common API while not requiring that you
use Solar's classes or pieces to do things. Of course the web
development world is a lot bigger than it was in the early days of
JSP/J2EE. And PhP has a huge part of that so the community is larger and
therefore the competing ideas is larger.

But you could argue, how is PDO not a standard interface like JDBC? How
was it not designed by the community and put out there for people to
implement their own methods for it?

I echo others in that there is not yet a common consensus. I have
started putting together my own framework as just a common directory
structure and code repository from projects that I have worked on. I
prefer my own code because I have this bit of OCD about using code that I
did not write if I do not fully understand every aspect of it, unless I
fully trust the source. I trust PEAR and often use some code from there.

Anyway, you asked about frameworks. I have been spending some cycles
looking at TYPO3 (http://typo3.com/) and so far it is pretty impressive.
I have heard from others that it is quite robust and almost a CMS in
itself. However I have not fully explored all of it so I will hold my
opinion on it until then. I also hear the learning curve for TYPO3 is
very steep but well worth the climb.

Sorry to intrude with my usual obnoxious behaviour, but this is starting to
affect my self-esteem (what's left of it). Am I the only one who has a
really hard time reading the blog posts in phpclasses.org? Everytime a
reference to this blog is posted I lose track of the discussion, because I
can't really grasp what Lemos is talking about.

I'd like to make some some constructive criticism, not just to Lemos but to
the community in general, since I think many of us need to improve our
writing skills:

1 - Don't make loooong boooring posts.

2 - Get to the point. Introduction are great when they are not two pages
long.

3 - Stick to the topic. Or use appropiate titles.

4 - If the topic is inherently long, use distinguishable headers and
subheaders. It's a pain in the ass to read a 5 pages long article that looks
the same everywhere, with no easy way to know what is the subtopic of what
are you reading now.

5 - Don't talk so much about your life! You can always make another blog for
that... Unless your personal experience can bring an unique insight of the
point you're trying to make.

That's all folks.

In my experience with the other frameworks (primarily Wasp, CakePHP,
Symfony, eZ Components, and Zend Framework), I've found that I was not
satisfied with the quantity of low-quality code they advocate. I have
a high standard for code quality, readability, maintainability, and
(more generally) semantics.

Because of this, I determined to build my own framework. This was a
few months ago, and Canvas[1] was the result of my labor. I produced
this framework while working on numerous projects at the university I
work at. This allowed me to build an application concurrently with the
framework and give it a good benchmark for usability, feature,
performance, etc.

Some of the features include pretty URLs and a fairly capable router,
a simplistic implementation of the ActiveRecord pattern (with a very
easy way to make adapters for your favorite flavor of RDBMS),
incorporation of Smarty for its templating, and usage of the MVC
pattern. (Of course, this list is hardly sorted by priority.)

A quick sample of using the ActiveRecord implementation:

class shoe extends Model {}
$shoe = new shoe();
$shoe->find_by_color('green')->delete();
$shoe->find_by_id(12);
$shoe->color = 'red';
$shoe->save();
$shoe->find_or_create_by_color('tangerine');
$shoe->find(array("where"=>array('color like ":color" or size >
":size", "color"=>"pink", "size"=>"11")))->all();

Do check it out.

The easiest way to do this is to use an absolute path in the URL.

Example:
/index.htm

This will lead to your homepage no matter what directory you are in.

Try using the freetype functions and see if you get "function xyz not

When you run the tool, just give the command-line options to PHP to
give it more RAM for memory_limit. :-)

Finding the memory leak in a Wiki-walker could take forever.

It will probably work, and you could find out for sure by just trying it.

It might be better to construct a single query using things like:

$company_ids = implode(', ', $_POST['reporton_company']);
$query .= " WHERE company_id IN ($company_ids) ";

This presumes you have already validated the company_ids.

However, if the number of companies, periods, and questions is SMALL,
the difference between one big query and a dozen little queries is
pretty minimal, and if you find the nested loops easier to maintain,
go for it.

What do you all recommend for testing the gui side of your php

For starters, the function is supposed to return 0 for countries that

As it stands now, it's going to return 1 / -1 randomly based on which
arg happens to be $a versus $b.

That's bad.

For some implementations of shuffle/sort routines, it will actually
crash.

I forget which implementation does this, but it's got to do with
caching the comparison result in a B-tree and then walking the tree
assuming that the comparison will be consistent...

Anyway, as far as "doesn't work" goes, you'd have to give us more info
about how it's not working...

cron runs the script from your home directory, not the directory the
script lives in.

The easiest thing is to just specify the full path to the include
files for the cron jobs.

There are functions "out there" to send POST data from PHP.

The canonical example can be found by Googling for "Rasmus Lerdorf
posttohost"

I have a function I use for doing POST transactions in PHP 4. Note that
the function just returns the text to send, another function does an
fwrite elsewhere. I'm also replacing some of my variables with hardcoded
values here to simplify the example, you can fix that as you will:

function make_post($message)
{
        $headers .= "POST /foo.php HTTP/1.1\r\n";
        $headers .= "Host: bar.com\r\n";
        $headers .= "Content-Type: application/octet-stream\r\n";
        $headers .= "Connection: keep-alive\r\n";
        $headers .= "Content-Length: " . strlen($message) . "\r\n";
        $headers .= "\r\n";
        return $headers . $message;
}

As far as I can tell, these are the absolute minimum set of headers you
can get away with for a POST transaction (If you know how to use less,
let me know, I use this in a situation where overhead matters).

Having done this before, several times, several different ways...

If it's US nationwide you can snarf the TIGER data for free to get:
zip code <-> longitude/latitude

You can then write a crude distance function just doing a Cartesian
distance with a 0.6 factor to convert degrees of arc to miles:

$distance = 0.6 * sqrt(pow($long2 - $long1, 2) + pow($lat2 - $lat1, 2))

This is of course utter [bleep] for an accurate calculation of
distance due to curvature of the Earth, but for finding stuff within N
miles of their postcode it's "okay" for US. Just don't try to fly an
airplane or pilot a boat by it.

You may even be able to create a function in your database of choice
to make it less messy.

Note that the number of zip codes is around 60K in the TIGER data, and
there have been a whole mess of zip codes added since then.

So if you want ALL the current zip codes, you have to shell out money.
:-( What I do, however, is when I run across a zip code that isn't in
the db, I just "guess" from the city/state and code number what other
zip codes are "near" it and then average those long/lat and shove it
in the db. Again, this is woefully inaccurate from a purist point of
view, but for calculating what's within N miles, it's fine and dandy.
And it don't cost me anything but a few minutes every month a new zip
code pops up.

Anyway, with such large tables, the query to calculate the distance in
a JOIN from your events to your zips table can get quite expensive.

So now it's time for a totally immoral non-denormalized
freak-out-the-DBA hack:

Add a longitude and latitude column to your events table, right after
the zipcode column, and default them to NULL.

Any time a zipcode changes, reset the longitude/latitude on events to
NULL.

Write a cron job that finds any events with NULL longitude and
latitude and copies the long/lat from the zips to the events for all
events with that same zip.

You'll want to run this cron job pretty often, especially if you have
a bunch of existing events that need to get initialized, but it's a
pretty cheap operation.

This cron job can notify you any time there is an unknown zip in the
events table that's not in the zips table, and then you can fake up
the long/lat as described above.

There are all manner of far more complicated ways of doing this, but
they are total overkill for what you need.

Considering that you said "any", I can't screw-up by answering.

Besides the pygmy running around with red feet, you might find this
of interest:

http://www.webpasties.com/xmlHttpRequest/index.html

As mentioned previously, there are TIGER data, but that may be an
overkill because you can build a entire Street Atlas type program
from that (been there, done that) -- it contains a massive amount of
data beside postal codes.

Can you get the postal code by themselves? The last time I looked at
TIGER data it was in quadrants of around the size of approximately a
township (6 x 6 miles).

You can write the fpdf file into ANY folder that PHP has write access
to, and there is no reason to put that folder directly into your web
tree.

You could certainly use /tmp with http://php.net/tmpname and friends,
or you could just set up some folder in a convenient location as world
writable.

If you then store the FPDF filename in a database, you can have a cron
job that checks every file in the directory, and each "active" record
in the database, and then move only the files that you have
cross-checked to be expected.

This makes it fairly secure, as somebody would have to hack both the
file system access and the db access to get the FPDF to go live.

There is a php.ini setting for how long the socket blocks connecting,
which you can reset with ini_set to 0.

Or maybe there's a separate setting for "non-blocking"...

Anyway, it's do-able with ini_set on some documented settings in
php.ini is the answer.

I added a Contributor's Note to this effect a couple months ago, but a
Notes Nazi decided it was not worthy of keeping. :-(

I think this is because you can sometimes use & to modify the contents
of the iteratee (is that a word?) so PHP does a copy there blindly,
whether you have & or not, because you might have & there sometimes.

I think Dmitry or Antony or ??? is looking at changing that so the
copy is only done when & is present.

At least, that's how I understand (or not) the upshot of a thread on
Internals.

It's entirely possible, even likely, that I'm completely
misunderstanding both of these threads. :-)

PHP List,

Recently I wrote a piece of code to scrape data from an HTML page.

Part of that code deleted all the unwanted text from the very top of the
page, where it says "<!DOCTYPE", all the way down to the first instance
of a "<ul>" tag.

That code looks like this:
ereg_replace("<!DOCTYPE(.*)<ul>", "", $htmlPage);

It works fine. But I noticed that on almost all the tutorial pages I
looked at, they just about always used preg_replace, and not ereg_replace.

It seemed that the main difference was that preg_replace required
forward slashes around the regular expression, like so:
preg_replace("/<!DOCTYPE(.*)<ul>/", "", $htmlPage);

But that didn't work, and returned an error.

Since ereg was working, though, I figured I would just stick with it.

Still, I thought it worth asking:

Is there any reason why either ereg or preg would be more desirable over
the other?

Why does the ereg work for the command above, but preg not?

Thank you for any advice.

From what I understand there are 2 schools of thought on regular
expressions. There is the Perl (Perl Compatible Regular Expressions -
preg) group and the POSIX (ereg) group. from the little I know they do
the same thing but with different symbols for things.
