This list is about PHP, and probably not the best place to ask that
question, but you need to look at CSS and javascript.

It was the negative lookahead that confused me, I see. The rest seems
pretty straightforward. Difficult, but straightforward.

Yes, this I know.

Nice. Very nice.

I don't do a lot, but it's a great tool to know when one needs it!
Thank you for the patient explanations.

How so? If, by multiple developers, you mean multiple *development
domains*, then yes, that'd need tweaking. Otherwise, i fail to see the
badness.

Multiple developers as in more than one person coding the application.
You'd be sharing the development environment (database, files etc) - not
what you want.
Think if your app was in cvs/subversion and you had someone working on
the same stuff at the desk next to you.

Hi all,
I'm new in PHP programming and I have a problem with this script. I need
to read a large file around 2Mb and several lines (28000). All start Ok,
but suddenly the script stop without message error.
<?php
$fichero="62007lg.txt";
$buffer = file($fichero);
$lineas = count($buffer);
foreach($buffer as $linea){
list($day, $month, $year, $hour, $min, $temp, $hum, $dew, $baro,
$wind, $gust, $wdir, $rlastm, $rdai, $rmon, $ryear,

}
?>
If only I print the variable $buffer all it's ok, but when I try to fill
all the matrix the script doesn't work. If I reduce the number of matrix
only a 3 o 4 it's Ok, but If I increase number of this matrix the script
crash again.
Perhaps it's a problem of memory of server, but my service provider say
me that this is not the problem.
Thank you very much
Andres:
The info is too poor to see what is wrong, maybe you need to review
a error_reporting() php function, o error_reporting php.ini variable i
send you some code:
<?php
error_reporting(E_ALL);
$fichero="62007lg.txt";
$buffer = file($fichero);
$lineas = count($buffer);
foreach($buffer as $linea){
$data = preg_split("/\s+/", trim($linea));
// trim removes all white spaces at the end and the beginning of
the string.
$k = 0;
foreach(array(
'mday', 'mmonth',
'myear', 'mhour',
'mtemp', 'mhum',
'mdew', 'mbaro',
'mwind', 'mgust',
'mwdir', 'mrlastm',
'mrdai', 'mrmon',
'mryear', 'mheat' ) as $var )
{
if(!isset($$var)) $$var = array();
array_push($$var, $data[$k]);
echo $var." => ".$data[$k];
$k++;

if you have the opportunity to have them input the time, you can then use
putenv("TZ=America/Los_Angeles") before any time operations and they
will be localized. it will accept any of the timezone library
definitions (or what you select for instance on unix libraries)
there's also a new date extension available as of one of the latest
php versions i believe that makes it even easier.
http://us3.php.net/manual/en/ref.datetime.php has the info.
for mysql data exchange you can use FROM_UNIXTIME and
UNIX_TIMESTAMP(NOW()) for example; if you dig it out from the database
and use the PHP functions it will localize it properly still. i don't
even fuss with this stuff anymore, i have a date formatting function
which takes $visitor['timezone'] (which is pre-populated with a
default, and overridden if the user has defined a different one) and
uses putenv("TZ=$foo") before i do the actual date/function calls -
it's been working flawlessly for years. i could probably update it now
to use the new extension too, natively maybe it would work slightly
faster than environment setting.
trying to detect the timezone offset from the browser i do not think
can be done consistently. i don't think i've seen anything that is
considered foolproof for that. maybe just DST checks...

Hello,
I have a small but somewhat annoying issue.
Whenever I open a socket to another server, the file is read very
quickly, but it takes the up to 30 seconds or so to close the connection...
Here is what I do:
$sever = "server.mit.edu";
$url = "/link";
$port = 80;
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$server_protocol = $_SERVER['SERVER_PROTOCOL'];
$valsencoded = "";
while (list($key,$value) = each ($content))
$valsencoded .= urlencode($key) . "=" . urlencode($value) ."&";
$valsencoded = substr($urlencoded,0,-1);
$content_length = strlen($valsencoded);
$headers = "POST $url $server_protocol
Content-Type: application/x-www-form-urlencoded
Host: $server
Content-Length: $content_length
";
// open socket
$socket = fsockopen($server, $port, $errno, $errstr, 60.0);
if (!$socket) {
$error = "ERROR: cannot contact Mailman server";
return array(false,$error,$error); }
if ($errstr) {
$error = "ERROR: fSockOpen Error ($errno): $errstr";
return array(false,$error,$error); }
fputs($socket, $headers); // send headers
fputs($socket, $urlencoded); // send post data
// "tried stream_set_timeout($socket,3)" here
// get the returned page
while (!feof($socket))
{
$buf = @fgets($socket, 2048);
$htmlreturned .= $buf;
}
fclose($socket);
If I put a debug 'echo "BUF: $buf\n" inside the while loop, I see the
returned html from the post show up pretty much immediately, within
about a second, maybe less.
However, the process 'stalls' after that for between 15-30 seconds, and
then ends correctly.
I have tried to use timeouts, but they did not have any effects (did not
really expect them to, but just in case).
My setup is Debian 4.0, php 5.2.0-8+etch7. Unfortunately I don't know
the other server OS's/applications.
I found similar questions in posts from 2002 and 2003, but there were no
replies (2002-04-30 guido.d.berger and 2003-11-25 thomas weber).
Any ideas greatly appreciated,
Alvar

just a wild guess, but try to use perhaps http1.0 instead of 1.1, and
try to add into the header that you prepare and send a
Connection: close\r\n

PHP can do anything. But the matter is where the host permits to do such.
// See the following algorithm
function exec_php($host){
if (its $host that runs php as a module) {
then it depends on the rights of $host
if ($host is in the group of root){
$host can do any thing.
} else {
$host will do those tasks that its been permitted.
}
}
}
If (you are root and running php as a CLI){
you can do anything (whatever you wish)
}.
if (you are normal user and running php as a CLI){
you cant do some specific task like killing process.
}
// see the function definition above.
exec_php(apache);
exec_php(IIS);
I think you got it.
sorry for the approach. But it makes clear logic. :)
Thanks.
