Phar::offsetUnset — remove a file from a phar
설명
bool Phar::offsetUnset
( string $offset
)
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.
매개변수

-
The filename (relative path) to modify in a Phar.
반환값
성공할 경우 TRUE를, 실패할 경우 FALSE를 반환합니다.
오류/예외
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.
