Для корректной работы с объектами Phar этому методу необходима установка значения php.ini phar.readonly в 0. В противном случае, будет выброшено исключение 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.
Список параметров

offset -
The filename (relative path) to modify in a Phar.
Возвращаемые значения
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
Ошибки
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.
