I guess you could stuck them there if you really wanted to, but there is
some broken feeling about that. Like keeping your motorcycle in dining room,
you can do it, but it is a bit odd.
Keep templates in files, or if you are using Smarty or TemplateTamer in
generated php code.

Hi,
Using the guide on the Zend site
(http://www.zend.com/manual/install.windows.php#install.windows.build)
I have successfully compiled and built the Win32 version of PHP using
Visual C++. For now I am building the CLI version - and it works just
great, but I have what is probably a very basic question - how do you
add the compile time options when building it?
For example I want to build the CLI version with --enable-memory-limit
so I can use the memory_get_usage() function - but I am simply not
sure where to specify this before building the project. I'm guessing
it lurks somewhere in the Project Settings for php4ts_cli?

I have to admit I did look in there, but couldn't see anything

Thanks for your replies,
after lots of investigation it appears that it is just my laptop that won't
disply the variable, maybe because I am using Norton Firewall? Whatever the
reason, is there an alternative server variable?

Possible. The REFERER HTTP field is OPTIONAL
-- See http1.1 spec (rfc2616) or this list archives.
So it's not a field anyone should rely upon.
More and more software (firewall, proxies, privacy tools)
just dont send it, or send it modified
(same thing for the UserAgent field, which can even
be modified on several browsers)
> reason, is there an alternative server variable?
No. It can be empty or even (easily) faked.

This is a variable that the client send you explicitly. Some firewall
software blocks sending it. You can even send a fake value. Basically,
you can't rely on it.

You need to compose a multipart/mixed message with a text part that is
your message and the attached part with is your file.
You may want to try this class that simplifies composing complex
messages. It also comes with examples and extensive documentation that
explain how compose the messages properly without much work.

Hi there,
I'm a web-developer and I work with PHP as often as I can (it's infinitely
preferable to ASP) and as a result of this I end up coding in lots of
different environments. Our local dev server is a windows machine which acts
differently to the multitude of *nix boxes which our clients run. Some have
safe-mode enabled (apparently a good safety measure for a shared-hosting
solution), some run with magic_quotes on, some with magic_quotes off,
register globals on/off, etc etc ad nauseum. Usually this isn't much of a
problem as I tend to only work on one major project at a time and I can set
up our local windows box to emulate the live server, but it would be very
useful to me if I could ask for your collective knowledge on building an
include file (or class) of common database functions. This class would take
into account whether the server has magic_quotes enabled and cater for it,
different login strings depending on the environment variables (for dev and
live environments) as well as catering for any other strange
platform-dependent niggles that I've left out. It'd also have methods to
fetch:
* just one specific value from the database
* an array of rows from the database
* run an arbitrary query (insert/update/delete) and return success/failure
and optionally populate the identity id/error message/etc.
I hasten to add that I'm not asking for someone to build this for me, but
rather asking for any pointers/tips for things I should watch out for or
links that might help. I've searched extensively for something like this but
haven't found one that does exactly what I want. Am I re-inventing the wheel
here? Does anyone else who works on multiple platforms have these problems?
Many thanks (in advance) for any help,
Regards,

Hi Keith,
using a database abstraction layer would be a good start. There are some
good ones in PEAR:
http://pear.php.net/packages.php?catpid=7&catname=Database
Namely PEAR::DB, PEAR::MDB and PEAR::MDB2. They offer the features you are
looking for.

Currently the online manual for php is great.
My concern is that the documentation for PECL extensions is almost
non-existent. Since some php extensions are being moved/replaced by PECL
extensions are we going to get non-existent documentation?
For example:
www.php.net/mime-magic
"This extension has been deprecated as the PECL extension fileinfo
provides the same functionality (and more) in a much cleaner way."
http://pecl.php.net/package/Fileinfo provides no documentation so what
these extra functions are, I have no idea. Worse, I now have no idea how
to do mime_content_type().
www.php.net/mcal
"Note: This extension has been removed as of PHP 5 and moved to the PECL
repository."
There is no mention of mcal on the pecl website.
I appreciate that PECL will more relevant to PHP5, but PHP5 is close is
the documentation close too?

To get a good slideshow you'll need to use client side instructions, aka
javascript. You're probably not going to get it to work so well using PHP
which is server side instructions.
Part of getting the slideshow to work is making the browser switch to the
next image and well, PHP doesn't really make the browser do anything.

As I was thinking about it before posting this thread, that was my

needs to load all of the images.
I am hoping there is some way to load the iamges one-at-a-time; as needed.

But I can also enter:

You need to catch if there's a quote in the $name too, and escape that.

One thing to remember is mysql_query() will execute just one (the first)
query so use of ; won't do anything in the above except break the
query. Still though the point is well taken, be sure to add slashes
(once) and put single quotes around the criteria ($name) and life will be
grand. Quotes around numerical values won't hurt (such as id = '$id')
although it's not required. If you choose not to do that then be sure
it's numerical before use (like cast it as an int, or check
is_numeric(), etc. ...). Some people check for ';' in the request
variable and if found yell at the user, that can be fun. bugs.php.net
does this.
In regards to the controversial magic_quotes_gpc PHP directive, I feel it
should remain on by default but if you know what you're doing then set it
yourself. Scripts that work everywhere should of course work perfectly
with it on or off. php.ini-dist (the default php.ini) has it on while the
php.ini-recommended has it off. You must know what you're doing to use
the 'recommended' version of php.ini. PHP is a newbie friendly language
and newbies are for the most part clueless and don't know what strings or
integers are, or why data should be escaped, or what data validation is or
why it's important. This is why magical quotes exist as without them
just think how many people would keep getting "malicious SQL" in their
code and blame PHP, or how seemingly random SQL syntax errors would crop
up. For these reasons dealing with "Why do I get \' everywhere????" type
questions is worth it, and why magic_quotes_gpc exists as a php.ini
directive.

Philip

I don't think I understand your question, but let me take a stab at it anyway.
There should be no reason to pass along the mysql connection ID in a form as
it will be quite useless when the page is submitted because these connections
are dropped when your PHP program ends execution. You will need to make a new
connection to the database in order to store the entered values from a form
submission.
If I didn't get your question right, please be more clear about what you mean
when you say MySQLconnection string.

Not sure I follow what you're asking, but you only need to open a
connection to the MySQL server when you want to run queries (select,
insert, update, etc.) against it. If the page with the form on it
doesn't need any mysql data for other parts of the page, then you don't
have to open it there. If you plan on putting the form results into a
db after the user posts it, then you need a connection on that page.

You ought to tell your registration-page to redirect to itself right
after the visitor hit the submit-button of your form.
This should to the trick:
[code]
<form name="form" action="<?php print $_SERVER['PHP_SELF']; ?>"
method="post">
[/code]
Therefore your script will have to check if something has been posted.
[code]
if (!empty($_POST) && isset($_POST['button_name'])) {
// perform validation, insert record into database, etc
}
[/code]
.. might do, while 'button_name' is the name of your form's submit-button.
Note: You should checkout the thread 'Form Submission' started on July
6th since this is appearently not the best way to check if the user hit
the submit-button.

Hello Afan.
On July 6th 2004 (or 2004-06-07 if you prefer ISO-dates)
shaunthornburghhotmail.com started a thread named 'Form Submission'.

Thanks for that URL, John.
Eventually CVS come to Afan's mind when he read "checkout" and "thread".

How are you checking the result? From a db? If so, run your query
before any output to the browser on the page where your form is posted
too (ex. SELECT * FROM users WHERE name = '$name' &&
password='$password'). If your query returns no results, redirect them
with the header() function.

What I usually do is set the form action to the same page as the above
code is applied to. Then I add an if statement at the top that checks the
login and redirects you to another page if login is successful. I think
you might want to give a name to your submit button as well, something
easy like name='submit'.
Then something like this at the top of the page:
if (isset($_POST["submit"])) {
...get user's password from database...
if ($_POST["password"] == $db["password"]) {
header("Location:members/index.php");
exit;
}
}
So if the login fails, they'll still be sitting at the login page. The
above code needs to be set before any HTML code, else the redirect won't
work.

I'm just starting with PHP, and I've been browsing the whole manual to
find how to solve the following problem:
1. An integer number is internally represented in 4 bytes. Say, for
instance, number 65 is represented by 0x00000041, that is the string
"\0\0\0\0x41", and not the string "65".
2. How can I write this representation into a file and then read back it
from the file?
Do you have any idea about this?

If the latter:
The pack and unpack functions are designed to do this (and more). You
could also manually do it yourself with something like this:
$sBuff = "\0\0\0\0x41"; // Read the data into a var
$iAnswer = ord($sBuff{0}) | ord($sBuff{1}) << 8 | ord($sBuff{2}) << 16

// Get the numerical value of each byte, then shift the bytes to get the

Thank you Chris. I finally got the solution to my problem using the

hello.
in an effort to more easily find products in the cart i'm building
i've given the ability to the user to click a letter from the alphabet
to search for all products whose product id starts with that letter.
currently each letter is hyper linked but i'd like to only link the
letters that have an occurrence in the database. in other words, if
there are no products in the database that start with the letter 'Z'
then i don't want it to have a hyper link.
i'm writing to the list to share my solution to this problem and
hopefully find a better way to do it (if one exists).
here is my solution:
1. pull a list of products from the database
2. truncate each product id down to it's first letter
3. remove all the duplicates
4. use this list to build the links.
as i loop through the alphabet i will only write a link for those
letters that occur in modified list. everything else will just be a
non-linked letter.
it's a pretty easy solution (concerning the logic behind it) but i
don't know if it's the best one and i haven't been able to come up
with anything else.

Do it with SQL
SELECT DISTINCT(SUBSTRING(`productName`, 1, 1)) FROM `productTable`
will give you only one of each of the starting letters that actually
occur in your database.

I would let sql do some of the work.
select count(*) from products where product_name like 'A%'
if count does not return 0 you have products that start with A

In the ldap_bind(), I have entered "my" dn to be able to authenticate

I could bind to the server twice, once to get an individuals "dn" , set
