Phar::running — Returns the full path on disk or full phar URL to the currently executing Phar archive
Returns the full path to the running phar archive. This is intended for use much like the __FILE__ magic constant, and only has effect inside an executing phar archive.
Inside the stub of an archive, Phar::running() returns "". Simply use __FILE__ to access the current running phar inside a stub.
If FALSE, the full path on disk to the phar archive is returned. If TRUE, a full phar URL is returned.
Returns the filename if valid, empty string otherwise.
Example #1 A Phar::running() example
For the following example, assume the file is within phar archive /path/to/phar/my.phar and the file is located at path my/file.txt within the phar archive.
$a = Phar::running(); // $a is "phar:///path/to/my.phar"
$b = Phar::running(false); // $b is "/path/to/my.phar"
