问题
I'm currently learning about PHP archives (Phars) and I know that in PHP __FILE__ always is the absolute filename of the currently executing file.
But to which file does __FILE__ point to if the script is inside a Phar? Is it the absolute filename of the Phar itself, or the Phar-URL to the current script inside the Phar?
For example: If I have a Phar located at /path/to/my.phar which contains a stub script, and a PHP script located at phar:///path/to/my.phar/inside/inner.php. What would __FILE__ be in the stub and inner.php?
回答1:
You could have tried it yourself.
The short answer is that __FILE__ has the full path; it's
phar:///home/cweiske/Dev/test/phar/test.phar/path/to/foo.php
in my test case - see http://p.cweiske.de/172
