Sorry, no it doesn't. But it's much clumsier than simply using a while-loop.

Excerpt from http://www.php.net/list
"*Note: * *list()* only works on numerical arrays and assumes the
numerical indices start at 0."
So the best way , in my opinion, to achieve this effect would be:
while(list($id, $someinfo) = mysql_fetch_row($result))
{
// Some stuff
}

Greetings all,
I am pulling records from a MySQL DB.
I am walking through the array using the whole.
if ( $row = mysql_fetch_assoc($result)) {
do {
// Some stuff
} while ( $row = mysql_fetch_assoc($result));
}
What I am wondering is if there is something I can do like.
if ( list ($id, $someinfo) = mysql_fetch_assoc($result)) {
do {
// Some stuff
} while ( list ($id, $someinfo) = mysql_fetch_assoc($result));
}
When I tried something like that
The variables where not populated.
Is there something I am doing wrong, or is this just something that cannot
be done (or is bad programming practice??)
Thanks.

Of course you can fix it! You can change your sessions handler and
save your session data in a database. For that you can use the
session_set_save_handler().

In a file, which is included into all my scripts, I defined constants
(for MySQL access). PHP claims these constants as undifined constants,
however, if I let them print out they have the right values
(HOST='localhost'; NOT: HOST='HOST').
Where do you print them out? In the file in which they're defined or somewhere
else?
I was wrong. In my test scritp I do not include any other file, just
define the constants, and print them out.
This suggests that your file containing the constants definitions was not
included. Which means you're not going to be able to connect to mysql (unless
by some fluke that your host happens to be 'HOST', etc).
This could not happen, since I did not inserted any other file in my
test script.
===========
But now I run the test script on my local machine without any notice.
My php -v:
PHP 4.3.2 (cgi), Copyright (c) 1997-2003 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend Technologies
The script:

<?php

You might check out http://photomatt.net/scripts/autop
"Call this function on the text you want to convert. Think of this
code like nl2br on steroids. This is basically a cross-platform set of
regular expressions that takes text formatted only by newlines and
transforms it into text properly marked up with paragraph and line
break tags. The line break part can also be turned off if you want."
It's really clean and useful

Hey,
I would just suggest that you "Explode" the data based on \n and
then "walk" through it adding <p> </p> and <br /> tags as necessary..
shouldn't be too diffcult.

I am pulling data from a database and using nl2br, which does the standard.

Again this is because of css and the designer I am working with. Is there a
maybe something as trivial as a extra few pixels between paragraphs may
be time better spent on other parts of the system? this is web not

built in function that can do something like this or another function out
there. So far I cannot see anything. Or is there a way to view the coding of
the nl2br function so I can create a new function modifying how it does it.
I'm guess that if you could program C that you would have already
downloaded the source and started hacking... so the answer is. yes and
probably not at this point in time, my utmost apologies if I am wrong!
Just asking so I do not have to create something from scratch.

If i run this code (php5):

I will get "B", but how i may get "A"?

the run function in b overrides the run function in a, thats why it
echo's "B"

looks good for GC, but seems bad for "in USE"
whenever there's an incoming new data which is not set in
$tracker[$current][...whatever you use now...], i have to go through
back all chunks of $tracker[] to archive "1hour tracking" effect
for $tracker[...]['site.view'][$siteid], only the first click is new,
cos they click same site
but for $tracker[...]['thread.view'][$threadid], almost all clicks is
new, cos they don't read same thread
each time i roll chunk, current online users make
$tracker[...]['site.view'][$siteid] is double from chunk[new-1] to
chunk[new]
too freq make it too many copies
but i'd guess it's ok for 'thread.view', "cos they don't read same
thread", no double
imagine if u guys write ip tracked(1 ip 1 view) counter, how will u
write the daemon?
database is slow imho
> If you make the $purge_time *TOO* small, smaller than the frequency with

no problem, i can do
$expred = floor((time() - 1hour)/$pure_time);
reset(..)
while(list ... each())
break if $key >= not expired

Hello,
I am setting up a program that requires allow_call_time_pass_reference to be
enabled. I've set allow_call_time_pass_reference = ON in the
/usr/local/etc/php.ini file
grep -n allow_call_time_pass_reference /usr/local/etc/php.ini
70: - allow_call_time_pass_reference = 1 [Code cleanliness]
167:allow_call_time_pass_reference = 1
But the program still calls for the option to be enabled. So I have run a test
file with the ini_get function, the code below.
------code-------
<html>
<head>
<title>Test Page</title>
</head>
<body bgcolor=#FFFFFF text=#000000>
<?php echo ini_get('allow_call_time_pass_reference'); ?>
</body>
</html>
----end code-----
Output page ==> blank
/usr/local/etc/php.ini has permissions set to 444 and listed in phpinfo.php
Suggestions?

You don't say whether you restarted apache; this is required to read and
utilise the changes to php.ini.

Hello!
How disable error messages when i send incorrect data into gzip* "extract"
functions, such as gzinflate or gzuncompress?
For example:
function _pack($data) {
$data = serialize($data);
$data = gzdeflate($data,9);
$data = base64_encode($data);
$data = urlencode($data);
return $data;
} # _pack()
function _unpack($data) {
$data = urldecode($data);
$data = base64_decode($data);
$data = gzinflate($data);
$data = unserialize($data);
return $data;
} # _unpack()
$s = _pack("123"); // K7YytlIyNDJWsgYA
$s = _unpack("K7YytlIyNDJWsgYA"); // 123
$s = _unpack("123"); // Warning: gzinflate() [function.gzinflate]: data
error
How disable this warnings? error_reporting(0) or @ operators does not help
me.
But I dont want use error_handler functions.
Thanks.

Hi all,
I have a foreach loop on an array and within that loop I need to find if

but that advances the pointer. Any tips on finding out if the array
pointer has reached the last element ?
