Phar::offsetUnset — remove a file from a phar
$offset
)Note:
此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出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.
offset
The filename (relative path) to modify in a Phar.
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
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.
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 ;
}
?>
