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
<?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; } ?>
