PHP 5.4.33 Released

Phar::offsetUnset

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

Phar::offsetUnsetremove a file from a phar

Descrizione

public bool Phar::offsetUnset ( string $offset )

Nota:

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.

Elenco dei parametri

offset

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

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.

Errori/Eccezioni

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.

Esempi
