Phar::offsetUnset

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

Phar::offsetUnset — remove a file from a phar

설명

public bool Phar::offsetUnset ( string $offset )

Note:
이 메쏘드가 Phar 객체에 작용하려면 php.ini 설정 phar.readonly을 0으로 설정해야 합니다. 그렇지 않으면, PharException이 발생합니다.

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.

인수

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

반환값

성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

오류/예외

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.

예제
