Phar::offsetUnset

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

Phar::offsetUnsetremove a file from a phar

说明

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.

参数

offset

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

返回值

如果成功则返回 TRUE,失败则返回 FALSE

错误/异常

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.

范例

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;
}
?>
