2 < $x <= 4 is a valid expression already.
2 < $x is evaluated first, and returns true/false
true/false is compared with 4 using <= and will always return TRUE,
since true/false will get typecast to 0/1 in order for the comparison
to be made.
At least, I THINK that's what will happen... Not sure on the
type-casting of something that I'd never code in the first place.
At any rate, it's already valid under current syntax, so you'd have a
HUGE backwards incompatibility issue to change it.

I personally would use:
((2 < $x) && ($x <= 4))
Yes, the extra parens are kinda bogus -- But they visually separate
the two tests.
Putting the 2, $x, and 4 in order is similar to the 2 < x <= 4
Algebraic notation.
It wouldn't bug me to see 2 < $x && $x <= 4, mind you.
In code I've read/written, it's seldom been a real problem.
In fact, if the author is CONSISTENT in their ordering, and SYSTEMATIC
in their tests/conditions/expressions, it doesn't even really matter
to me if they use 2 < $x && $x <= 4 or $x > 2 && $x <= 4, so long as
it's the same way in all their code.

Probably not incredibly difficult, per se, and performance would not
suffer in any measurable way...
You'd just break a few zillion existing scripts that, whether the
authors know it or not, rely on the current behaviour.
I suspect it would also unearth a large number of previously
un-noticed bugs :-)

If you did read that, it was a REALLY BAD thing to have been written
by anybody anywhere. :-)
[Maybe that goof that decided PHP wasn't ready for Enterprise use we
were discussing a couple days ago. He was great at writing FACTUALLY
INCORRECT statements to shore up his pathetic arguments. :-)]
PHP has a very precise order of operations with Operater Precedence:
http://php.net/manual/en/language.operators.php#language.operators.precedence
In fact, some of those are VERY common pitfalls for newbies.
&& || versus AND OR often trips up beginning scripters.
Not only does PHP not always evaluate from left-to-right due to
precedence, even within the precedence ordering, some operators are
right-to-left associative:
$x = 2;
$y = 5;
$x = $y = 3;
Here we have a "tie" in order of operations between two assignment
operators.
Since = is RIGHT associative, the tie-breaker is to read from RIGHT to
LEFT and do the operations in this order:
$y = 3;
$x = $y;
So both $x and $y are 3.
[WRONG]
If = were LEFT associative, which it's NOT, you'd end up with $x being
5 and $y would still be 3:
$x = $y;
$y = 3;
[/WRONG]
'Course, $x = $y = 3; is probably Bad Practice anyway...
Though I guess I've seen:
$x = $y = $z = 0;
at the top of enough functions to understand and accept that it's a
convenient way to initalize all three variables to 0...
I don't LIKE it, but I can live with it.

You could maybe check with PHP-Internals to see if they believe that
nobody's relying on the current behaviour with < > <= >=, and then
there's no problem adding it, but I wouldn't get yer hopes up.
PS Is (2 < $x >= 0) a syntax error, or would you allow that silly
expression? :-)

Please ask on a Moodle support list, or on their official site. This is

Would you care to elaborate with some reasons for this? I find it very
useful as a naming convention for any sort of "external variable" or
user input, so when reading my code I can immediately tell what came
from where.
Prepending the variable name with an underscore happens to be what PHP
does ($_SERVER, $_GET, $_POST, $_COOKIES, so on...) so it is simpler
just to carry on that convention.

This is exactly the reason why you shouldn't do it. You don't know when
PHP might come out with a new 'superglobal' that conflicts with your
$_Myfunc.
In addition, when PHP prepends $_ to a variable name, it means
something. Specifically, it means that the variable is a 'superglobal'.
The only exception to this that I know of is $GLOBALS.
For the reasons above, I avoid creating user variables with $_ --
although there is no rule regarding variable names (other than the
syntax rules).
Sometimes, just because you can do something, doesn't mean you should.

I understand what you're saying, and I had thought of that previously.
However, the only reason I can think of that PHP would create a
$_SAFE_POST superglobal is if it were to be doing exactly what I am
already doing with it, in which case it wouldn't matter.
What's more, if they did implement a $_SAFE_POST superglobal for
whatever reason, my scripts would continue to work anyway, because they
don't rely on the special functionality that could be introduced for
that variable. Example:
$_SAFE_POST = array_map('sanitise_func', $_POST);
would simply overwrite any existing $_SAFE_POST superglobal anyway.
Most of the time if I'm creating my own global variables I actually use
two underscores anyway, like $__db or $__user. I just use one underscore
when I sanitise user input because it looks cleaner.

$_XYZ use the $_ because they are superglobals.
If your $_MyVar isn't a superglobal with http://php.net/runkit, it
probably shouldn't be $_
That said, I do the same thing, for the variables I make that I WISH
were superglobals. :-)
Given that the list of superglobals is incredibly short, and that I
know damn well the $_PATH variable I made up is NOT a superglobal,
I've never had a problem doing this.
But if I worked somewhere and the boss say "Don't do that" I'd just
fix it and not argue, that's for sure.
By all rights, $GLOBALS should be $_GLOBALS, but it existed way too
early in PHP history and re-naming it would be a real pain.
PS I *think* this explanation of $_ is in the manual, but maybe it's
from some book/interview/paper from Rasmus or something... Sorry,
can't remember where.

This isn't necessary if you don't import variables, but rather retrieve
them one by one as in the example I showed. Since there you essentially
denote valid input vars by virtue of retrieval rather than automating
the import.

$_FILES['userfile'] is going to be an array.
It will have elements like 'name', 'tmp_name', 'error', 'size' etc.

Ignoring the fact that $_FILES['userfile'] is an array and probably
isn't what you want to pass to the AddAttachment method (although I know
nothing about phpmail specifics), shouldn't that be:
$mail->AddAttachment($_FILES['userfile']);
(square brackets, as $_FILES is an array, not a function)

If you REALLY don't want to specify all the column names (as suggested
by others) you *CAN* use NULL for the auto_increment field value, and
MySQL will do the right thing.
create table example (
example_id int(11) unsigned auto_increment unique not null primary key,
example text
);
INSERT INTO example VALUES (NULL, 'This is an example.');
It's probably better to get in the habit of specifying columns,
though, because eventually you'll have tables where only SOME columns
are known at the time of the initial INSERT, and others will be
UPDATEd later, or not at all, depending on the application.
So you *CAN* do this, but I'm recommending that you don't.

This assumes you have a script named "topics.php" and that script uses
GET parameter "topic_id" to determine which Topic to display in your
Forum.
It was only a WILD GUESS as to how your forum topics would be
displayed, really... Well, not totally a wild guess, since that's
pretty much how they all work, though they will use different names
for stuff:
forum.php?id=$topic_id
view.php?thread_id=$topic_id
show.php?subject_id=$topic_id
.
.
.
Perhaps you need to set this aside for a while, and work on showing a
list of topics, and the display page for something chosen from that
list.
After you've written that, the link to put in there gets a LOT easier
to figure out.

The files will be in your "tmp" directory (specified in php.ini).
If you change that to be some directory that does not exist, or
/dev/null on a Linux box, then the files won't ever actually live on
your server at all, I don't think...
Well, they will "live" in RAM while Apache accepts the POST, passes it
on to PHP, and then PHP stores it in the directory you chose in
php.ini (the default is to use the OS System default temp directory)
Hope that helps.
NOTE:
Having an invalid temp directory for file upload MAY trigger an error
message in PHP. You may not like that, and may want to test for it,
or use /dev/null for the directory... Oooh, that may not work
either...

PHP's wordwrap function may have an optional argument to FORCE it to
never be wider than X characters, but I don't think so...
You could write your own wordwrap function in about an hour, max.
Or take one of the umpteen wordwrap functions from before PHP had a
built-in wordwrap function.
If you are using CSS, and if you know the font and font-size it will
display in, I guess you could even fire up GD or PDF or something and
use the string length functions there with the same font and font-size
and figure out exactly where you should break up the string...
I'd cheat a little conservative if you REALLY need it to be no more
than 100px exactly, because I'm guessing differences in rendering will
make the text wider/narrower than GD thinks when the browser renders
it.
Actually, if you go to THAT much effort, and if it's really crucial,
maybe you should display the text as image. Ugh. Still, if it HAS to
be 100px or less, you could do that, and be CERTAIN of the width.

http://www.php.net/wordwrap
string wordwrap (string str [, int width [, string break [, bool cut]]])
"If the cut is set to 1, the string is always wrapped at the specified
width. So if you have a word that is larger than the given width, it is
broken apart. (See second example)."
Example:
$string = wordwrap($string, 30, '<br>', true);

That does the exact same thing as:
print(wordwrap($foo, 30, '<br />', true));
Which is much more convenient if you're not already using Smarty.

Windows uses \r\n
Linux uses \n
Mac uses \r
Depending on what tools you use to read/write/create the files, and
where the data comes from, it's possible that you have any of those
formats.
This is especially true of FORM data from a TEXTAREA.
I frequently do this:
$text = $_POST['text'];
$text = str_replace("\r\n", "\n", $text);
$text = str_replace("\r", "\n", $text);
//Now I *know* it's in Linux newline format.

Thanks, Richard. Jochem pointed that out earlier. I really should have

If you're reading this text from a file, and then splitting it into

Install it on a different box, which has IIS/ASP, and *NO* PHP was
ever installed.
It can be any old box out of the closet, that you wipe and install
Windows, IIS, ASP and NOTHING else.
Same bug?
Then it CANNOT be a PHP bug, can it?
Even PHB from Dilbert should understand that one...
Though, honestly, it sounds like they just aren't going to listen to
facts -- not even the ones about how much this is costing them.
I may not be making ends meet, but I sure am happy not to have to put

Maybe PHP 5 + SimpleXML really is that simple, but...
For 20 lines of text, you could probably write a function with explode
and implode and have it done in an hour...
<?php
$bars = explode("<bar", $text);
while (list(, $bar) = each($bars)){
preg_match('/.*id="(.*)" name="(.*)".*/', $bar, $parts);
$id = $parts[1];
$name = $parts[2];
//Do whatever you want with id and name and:
echo "<bar id=\"$id\" name=\"$name\" />\n";
}
?>

Just a thought - and I know it's a little late, sorry.
Have you considered writing a wrapper for mysql_query() that logs its
parameters?
You could:
1. do a search and replace on your code replacing 'mysql_query' with
'mysql_query_wrapper'.
2. put a function definition for mysql_query_wrapper() in an auto_prepend file.
function mysql_query_wrapper()
{
$args = func_get_args();
$backtrace = debug_backtrace();
$details = $backtrace[0];
log(sprintf("%s (line %d): %s\n", $details['file'],
$details['line'], $details['args'][0]));
return call_user_func_array('mysql_query', $args);
}
3. Let your users hammer it for a week or so. Your log should then
contain all the queries used by the app on a day-to-day basis and
where they were called from.
5. Do a grep for all lines containing 'mysql_query_wrapper' and diff
it with your log file. That should give you the locations of the
(hopefully few) remaining queries.
cut -d ':' -f 1,2 logfile.txt | sort --unique > recorded_queries.txt
fgrep -n 'mysql_query_wrapper' /path/*.php | cut -d ':' -f 1,2 | sort
--unique > all_queries.txt

Hello,
Curently I do it with wget and by hand using a bash script,
but like to integrate it into my php4 webinterface.
What I need is:
1) INPUT-Form where I can type the URL of
a html/php (or something like this) page.
when submited,
2) the php script download the page and create an md5sum
3) look in a database where it check the whole URL wheter
it is already there and if
YES check the md5sum
3.1) if equal drop the URL and stop here
3.2) if different calculate original md5sum
and insert it into database
NO calculate original md5sum and insert it into database
up to here it is working fine.
4) now get all FULL URIs from the page requisites
*PAFF*
How can this be done ?
Please note, that the files should be renamed to md5-hashes and
reinseted into the original page. Then safed all files into ONE
directory with names as md5-hashes.
Note: I am talking about (curently) 127.000.000 files.
It is curently in a Raid-5 with 7 x 147 GByte but because
a major upgrade of Hardware to 15 x 300 GByte the number
of files will increase
Curently I do not know, whether I should use ONE Raid with
15 HDDs, TWO with 7 HDDs, three with 5 HDDs or 5 with 3 HDDs.
Maybe I will run into a performance problems with the Inodes
which I already have... (I think)

<?php exec("wget $URL", $output, $error);?>
http://php.net/exec
You really don't want to re-write all of wget.
And I doubt that anything in PHP to do what wget does will out-perform
exec + wget
You can also exec() your bash shell script, or combine the wget and
your script into one script to execute.

I assume you know the html to create a web form, and how to use the
$_GET and $_POST variables. If not, go learn php, and then read the
rest of my reply.

Assuming that allow-url-fopen is enabled you can
$content = file_get_contents($url);
$md5hash = md5($content);

Hi,
I have a website, which uses themes.
The web tree looks like this:
* webroot
o *themes*
+ default
# images
+ red design
# images
o *index.php*
Let's say I choose "red design" theme. All the pictures the theme is
using will have URL like "www.site.com/themes/default/images/bla.jpg".
Is there a way how I can change it? So noone can see I have themes in
that directory?
I was thinking about: ShowImage.php?blah.jpg, but that is too slow... :-/
Any help appreciated.

You can use this, modified to fit your specific needs:
<?
// THE NAME OF YOUR IMAGEFILE
$imagefile = "bla.jpg";
//PATH WHERE THE IMAGES ARE STORED ON OUR WEB SERVER
$path = "/home/user/website.come/themes/default/images/" . $imagefile;
//TELL THE BROWSER WE ARE SENDING AN IMAGE
header("Content-type: image/jpeg");
//OPEN THE IMAGEFILE
$jpeg = fopen($path,"r");
//READ THE IMAGEFILE
$image = fread($jpeg,filesize($path));
//SEND IT DOWN THE PIPE
echo $image;
?>
Call this image.php
Call it in a webpage using this:
img src=image.php
Of course, you will need to figure out how to specify which image you
want loaded as $imagefile - be it a database, random selection, etc.

This is another rather hackish attempt at using the tokeniser.
It turns this:

Does anyone know of a good polling script that is, obviously, written

What are you polling?

It's for a contest so that people can come in and read about the people
who are entered and then vote on which one they think should win. I
would like to at lease be able to restrict the polling by IP (using
mysql) and maybe cookies as well.
There seems to be a ton of polling packages out there in php but I'm
hoping someone on the list will have experience with one and can
recommend it instead of myself having to sift through a ton of them. :)
thanks!

Hi
We have a content management system running for a client of ours. It was
earlier on Debian and Apache 1.3 . Now they have moved to Redhat Ent and
Apache 2. The PHP and MySQL versions are the standard packages available
with Redhat Ent and the same version as before. However we can see that it
now rejects any query which has a quote in it. Earlier it used to work fine..
So I am wondering whether there is any setting in PHP which controls it.
Not sure if I am making sense. Any pointers would be greatly appreciated.

If I do that then i get this error
Fatal error: Can't use function return value in write context in
myfilename line 2
What does that mean. And one more thing, on the code where it says
if( !isset( $_SESSION['userName'] ) )
Does that mean that in this code
<form name="form1" method="" action="">
the method is session?
