(no version information, might be only in CVS)

Phar::offsetUnset -- remove a file from a phar

## Description

bool Phar::offsetUnset ( string offset )

This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. offsetUnset is used for deleting an existing file, and is called by the unset() language construct.

## Liste de paramètres

`offset`

  The filename (relative path) to modify in a Phar.

## Valeurs de retour

Cette fonction retourne `TRUE` en cas de succès, `FALSE` en cas d'échec.

## Erreurs / Exceptions

if phar.readonly is `1`, BadMethodCallException is thrown, as modifying a Phar is only allowed when phar.readonly is set to `0`. Throws PharException if there are any problems flushing changes made to the Phar archive to disk.

## Exemples

Exemple 1. A Phar::offsetUnset() example

`<?php $p = new Phar('/path/to/my.phar', 0, 'my.phar'); // deletes file.txt from my.phar by calling offsetUnset unset($p['file.txt']); ?>`
