Hi,
Facts:
1. I have the following four scripts: a.php, b.php, c.php and d.php 2. a.php defines a function named foo. 3. b.php includes c.php 4. c.php defines a function named foo
Case I: d.php looks like this:
<code> include "b.php"; include "a.php"; </code>
This causes a fatal error that says that foo cannot be redeclared.
Case II: I change d.php to look like this:
<code> include "a.php"; include "b.php"; </code>
This does NOT cause the same fatal error. When I called foo from d.php, it called the foo defined in a.php
Can anyone explain why a fatal error wasnt caused in Case II? I am using PHP version 4.2.3
Thank you,
Shaunak Kashyap
Perhaps you have a function_exists() (or similar) call wrapping the declaration of foo() in c.php?
If you're using this same function in multiple files and it's the same funciton, you ought to put it in its own file and require_once() the file in the places where you need it. That way, you don't get this problem. You could also wrap all of the declarations in funciton_exists() calls.
