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.
Returns the filename if valid, empty string otherwise.
示例 #1 A Phar::running() example
For the following example, assume the phar archive is located
at /path/to/phar/my.phar.
<?php
$a = Phar::running(); // $a is "phar:///path/to/my.phar"
$b = Phar::running(false); // $b is "/path/to/my.phar"
?>
