Phar::offsetUnset

Phar::offsetUnset

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

Phar::offsetUnsetremove a file from a phar

Description

public bool Phar::offsetUnset ( string $offset )

Note:

This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

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.

Parameters

offset

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

Return Values

Returns TRUE on success or FALSE on failure.

Errors/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.

Examples

Example #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;
}
?>
