Hi there,
i have following problem:
Assume we have a "cron.php" which is called every hour by a cron job.
This cron.php should then be used to execute other php-scripts
"script1.php", "script2.php".
For a pitty our server has Safe-Mode activated so we arent able to
shell_exec / exec those files. So we came up with the idea: Lets include
those scripts using include(). But this lead us to another problem:
Namespace conflicts (our server is running php 2.7.2) especially with
classes and constants.
Example:
<<script1.php>>
<?php
class A {
public function test(){ echo "im class A at script 1"; }
}
?>
<<script2.php>>
<?php
class A {
public function test(){ echo "im class A at script 2"; }
}
?>
<<cron.php>>
<?php
include('./script1.php');
include('./script2.php');
?>
Cron.php will raise a "cannot redefine class A" error.
So my idea is to continously rename every occurence of class names and
constants in the scripts by adding a suffix (ie. class A_123 and class
A_234). Do you have an idea how to implement this during the deployment
step?
Sincerly yours

"2.7.2"? I'm guessing 5.7.2.
The only way I could think of would be to use namespaces, but that
would involve some reworking.
And only for V5.3+

Pretty sure you're *not* running PHP 2.7.2. If you are, give up now.

Well of course, you would get that error. But I'm completely lost beyond
that point. Why must both scripts use the same class names in them? Why
not call the class in script2.php "B" instead of "A"? I'm guessing you
left out a huge piece of explanation here.

Is it OK to have session_start as an include?
I have something like this:
// Session init
session_start();
function sKill() {
session_destroy();
session_unset();
header ("Location: login.php");
exit();
}
function sInt() {
header ("Location: login.php");
exit();
}
if (!(isset($_SESSION['sLogin']) && $_SESSION['sLogin'] != '')) {
sKill();
}
// Session variables
if (!isset($_SESSION['sUser'])) { sInt(); } else { $sUser =
$_SESSION['sUser'];}
if (!isset($_SESSION['sEmail'])) { sInt(); } else { $sEmail =
$_SESSION['sEmail'];}
if (!isset($_SESSION['sType'])) { sInt(); } else { $sType =
$_SESSION['sType'];}
if (!isset($_SESSION['sTime'])) { sInt(); } else { $sTime =
$_SESSION['sTime'];}
if (!isset($_REQUEST['id'])) { $id = 0; } else { $id = $_REQUEST['id'];}
// Kill the session if the ids dont match.
if ($id != $_SESSION['id']) {
sKill();
}
// Kill the session if timeout is exceeded.
if (isset($_SESSION['LAST_ACTIVITY']) && (time() -
$_SESSION['LAST_ACTIVITY'] > $sTime)) {
sKill();
}
Can I just call this session.php and include it at the beginning of each file?
