require_once真的在哪儿？

Question

I have 2 installations of php for 2 versions of joomla on my windows computer.

I get this error when executing an application:

PHP Warning: Uncaught exception 'ErrorException' with message 'require_once(Cache/Lite.php): failed to open stream: No such file or directory' in C:\xampp\apps\joomla\htdocs\libraries\joomla\cache\storage\cachelite.php:79

The line is

require_once 'Cache/Lite.php';

Well there IS this file called Lite.php in:

C:\xampp\php\pear\Cache\Lite.php

I have a second php version installed, this might interfere. None the less, I removed the PATH entry of the second php version. I copied the folder to the second php installation, and I added the other php version to the path. Didn't help.

How can I find out where require_once '' is actually looking for?

Or how would you try to fix this?

Answer 1

You can see the include path by:

<?php
echo get_include_path();
?>

If you need to change this, then you will need to modify your php.ini file or use set_include_path()

Remember to include your current include_path, when setting a new one:

<?php
$new_path = '/usr/lib/pear';
set_include_path(get_include_path() . PATH_SEPARATOR . $new_path);
?>
