Phar::offsetUnset
Phar::offsetUnset
(PHP >= 5.3.0, PECL phar >= 1.0.0)
Phar::offsetUnset — remove a file from a phar
Description
public 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.
Parameters
-
offset -
The filename (relative path) to modify in a Phar.
Return Values
Returns TRUE on success or FALSE on failure.
Errors/Exceptions
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.
Examples
Example #1 A Phar::offsetUnset() example

$p = new Phar('/path/to/my.phar', 0, 'my.phar');
try {
// deletes file.txt from my.phar by calling offsetUnset
unset($p['file.txt']);
} catch (Exception $e) {
echo 'Could not delete file.txt: ', $e;
}
