对php.ini中的include_path感到困惑

Question

I have this line in php.ini

include_path = ".;C:\xampp\htdocs\zend\library;C:\xampp\php\PEAR"

What exactly is the . in front of the string?

And what does the line do, exactly? I know it includes the paths, but what exactly happens behind the scenes? Maybe this is a dumb question but I'm asking anyway :-)

Answer 1

. adds the current working path to the include path

What all this does is that if you say:

Include ( 'some_file.php' );

PHP will look for that file in the directories specified in the "include_path". It will look in the order you specify the directories.
