Описание

bool Phar::offsetUnset ( string $offset )

Забележка: Този метод изисква стойността на phar.readonly в php.ini да бъде 0, за да работи за обекти Phar. В противен случай ще бъде хвърлено PharException.

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.

Параметри

offset

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

Връщани стойности

Връща TRUE при успех или FALSE при неуспех.

Грешки/Изключения

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.
