Phar::offsetUnset — Remove a file from a phar

Açıklama

public Phar::offsetUnset(string $localName): void

Bilginize:
Phar nesneleri ile çalışmak için, bu yöntem phar.readonly php.ini yönergesine 0 atanmış olmasını gerektirir. Aksi takdirde bir PharException istisnası oluşur.

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.

Bağımsız Değişkenler

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

Hatalar/İstisnalar

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.
