How can I get the dir of a php script that's running in CLI?

I have a CLI PHP script and I need to know wh开发者_开发技巧at directory it's currently running in. Because of some operations, including getcwd(), the directory has changed a bit.

How can I do this?

You can use the __DIR__ predefined constant.

Perhaps you want: dirname(__FILE__)
