Pear Class Call problem

Pear installed with the class, the default installation path, the call found in each class require_once (' xx '), ' xx ' does not exist in the specified directory, that is, the path is inconsistent, so call this class will be an error, why this? Do you want to go to the source of the installed class to modify the path of the calling class? Or is it another reason?

Reply to discussion (solution)

When Include_path is not set in php.ini, the Pear installation directory is included in the Include_path
If you specify include_path and you want to use pear, you should attach the Pear installation directory to include_path

Then you call the full path, such as require ("d:\x\xx\1.php");
Or first look at the results of Echo dirname (__file__),
Or use Get_include_path to confirm what the current inclusion path is

I understand that the original class of require_once (' xx ') inside the ' xx ' is relative to the php.ini set in the relative path of Require_path, so on, I understand wrong before, thought Require_ Once is relative to the current directory relative to the path, thank you upstairs two reminders

You understand nothing wrong!
The relative path to the embedded file is found in the directory specified by Include_path.
