# Phar::mapPhar

(PECL phar:1.0.0-1.2.1)

Phar::mapPhar — Reads the currently executed file (a phar) and registers its manifest

### Beschreibung

mixed Phar::mapPhar ([ string `$alias` [, int `$dataoffset` ]] )

This static method can only be used inside a Phar archive's loader stub in order to initialize the phar when it is directly executed, or when it is included in another script.

### Parameter-Liste

`alias`

  The alias that can be used in phar:// URLs to refer to this archive, rather than its full path.

`dataoffset`

  Unused variable, here for compatibility with PEAR's PHP_Archive.

### Rückgabewerte

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

### Fehler/Exceptions

PharException is thrown if not called directly within PHP execution, if no __HALT_COMPILER(); token is found in the current source file, or if the file cannot be opened for reading.

### Beispiele

Beispiel #1 A Phar::mapPhar() example

mapPhar should be used only inside a phar's loader stub. Use loadPhar to load an external phar into memory.

Here is a sample Phar loader stub that uses mapPhar.

`<?php
function __autoload($class)
{
include 'phar://me.phar/' . str_replace('_', '/', $class) . '.php';
}
try {
Phar::mapPhar('me.phar');
include 'phar://me.phar/startup.php';
} catch (PharException $e) {
echo $e->getMessage();
die('Cannot initialize Phar');
}
__HALT_COMPILER();`
