Phar::running — Returns the full path on disk or full phar URL to the currently executing Phar archive

### Description

final public static string Phar::running ([ bool `$retphar` = true ] )

### Parameters

`retphar`

  If `FALSE`, the full path on disk to the phar archive is returned. If `TRUE`, a full phar URL is returned.

### Return Values

Returns the filename if valid, empty string otherwise.

### Examples

Example #1 A Phar::running() example

`<?php
$a = Phar::running(); // $a is "phar:///path/to/my.phar"
$b = Phar::running(false); // $b is "/path/to/my.phar"
?>`
