# Phar::offsetUnset

(PHP >= 5.3.0, PECL phar >= 1.0.0)

Phar::offsetUnset — remove a file from a phar

### Opis

bool Phar::offsetUnset ( string `$offset` )

> Informacja: Ta metoda wymaga ustawienia w php.ini wartości phar.readonly na 0 aby działała z obiektami Phar. W przeciwnym przypadku, klasa PharException zwróci wyjątek .

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.

### Parametry

`offset`

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

### Zwracane wartości

Zwraca `TRUE` w przypadku powodzenia, `FALSE` w przypadku błędu.

### Błędy/Wyjątki

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.

### Przykłady

Przykład #1 A Phar::offsetUnset() example

`<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar');
try {
// deletes file.txt from my.phar by calling offsetUnset
unset($p['file.txt']);
} catch (Exception $e) {
echo 'Could not delete file.txt: ', $e;
}
?>`
