I found the reason of this issue : SELinux
by defaut, SELinux is enabled on CentOS5.5 => httpd runs with
"restricted rights"
If I temporary disabled SELinux + restart httpd => "ps -A" from my
script runs as expected
$ setenforce 0
$ /etc/init.d/httpd restart

Hi,
I want to get the list of running processes. also, I call exec() with
"ps -A"
(ps -A displays almost all processes of all users)
Unfortunatly, the output of "ps -A" seems incomplete
the test file test.php:
<?php
unset($buf);
unset($res);
exec("ps -A", $buf, $res);
for($i=0; $i < count($buf); $i++)
{
echo($buf[$i]."<br>");
}
?>
If I run the test.php under the context of httpd (from
http://<server>/test.php), I can see only a subset of running
processes (some processes of user "apache")
PID TTY TIME CMD
3207 ? 00:00:00 httpd
3359 ? 00:00:00 httpd
3360 ? 00:00:00 httpd
3361 ? 00:00:00 httpd
3362 ? 00:00:00 httpd
3363 ? 00:00:00 httpd
3364 ? 00:00:00 httpd
3365 ? 00:00:00 httpd
3366 ? 00:00:00 httpd
3569 ? 00:00:00 ps
If I run the same script directly from php (from user apache) , I can
see *all* processes as expected
# sudo -u apache php -f test.php
PID TTY TIME CMD<br>
1 ? 00:00:01 init<br>
2 ? 00:00:00 migration/0<br>
3 ? 00:00:00 ksoftirqd/0<br>
4 ? 00:00:00 watchdog/0<br>
5 ? 00:00:00 events/0<br>
6 ? 00:00:00 khelper<br>
[...]
Is it a problem with exec() or with "ps -A" or with .... ?
any ideas ?

Hey.
Depends on your customisation needs. If you need something robust and don't
need anything very specific - you should be ok with Drupal, Joomla or
something similar. If you are going to need a lot of complex internals that
are not in these engines - you may want to try some lightweight flexible
framework like CodeIgniter or Kohana.

Hello,
I have a formula that says, if 'specialprice' is not empty and it is
lower than 'unitprice', use 'specialprice', otherwise use 'unitprice':
<?php $result = mysql_query("SELECT
LEAST(unitprice,ifnull(specialprice,'9999')) AS used_price FROM catalog WHERE
itemid='WB1836C'",$db);
printf('<b><font color="#555555">Your Price:</font> $%s</b><br />',
number_format(mysql_result($result,0,"used_price"),2)); ?>
What I'd like is to add a starting and ending date and if today's date
is between those dates, then do the above formula, otherwise if today's date is
not between those dates, then just use 'unitprice'.
This is starting to get too complex for me, so I need some help. ;)
Hopefully this makes sense. If I need to be clearer, please let me know.
Thanks!
Angela
