Phar::running — Returns the full path on disk or full phar URL to the currently executing Phar archive
$retphar= true ] )
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.
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 phar archive is located at /path/to/phar/my.phar.
$a = Phar::running(); // $a is "phar:///path/to/my.phar"
$b = Phar::running(false); // $b is "/path/to/my.phar"
