# Phar::setAlias

(PECL phar:1.2.1)

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

### Description

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

> Note: Cette méthode nécessite que la variable de configuration INI phar.readonly soit définie à 0 pour fonctionner avec les objets Phar. Sinon, une exception PharException sera lançée.

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.

### Liste de paramètres

`alias`

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

### Valeurs de retour

### Erreurs / 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.

### Exemples
