# Phar::setAlias

(PECL phar:1.2.1)

Phar::setAlias — Set the alias for the Phar archive

### Beschreibung

bool Phar::setAlias ( string `$alias` )

> Hinweis: Diese Methode des Phar Objekts funktioniert nur wenn die php.ini Einstellung phar.readonly auf 0 gesetzt ist, sonst wird eine PharException geworfen.

Set the alias for the Phar archive, and write it as the permanent alias for this phar archive. An alias can be used internally to a phar archive to ensure that use of the phar stream wrapper to access internal files always works regardless of the location of the phar archive on the filesystem. Another alternative is to rely upon Phar's interception of include() or to use Phar::interceptFileFuncs() and use relative paths.

### Parameter-Liste

`alias`

  A shorthand string that this archive can be referred to in phar stream wrapper access.

### Rückgabewerte

### Fehler/Exceptions

Throws UnexpectedValueException when write access is disabled, and PharException if the alias is already in use or any problems were encountered flushing changes to disk.

### Beispiele

Beispiel #1 A Phar::setAlias() example

`<?php
try {
$phar = new Phar('myphar.phar');
$phar->setAlias('myp.phar');
} catch (Exception $e) {
// handle error
}
?>`
