Phar::decompress
(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)
Phar::decompress — Decompresses the entire Phar archive
Beschreibung
Hinweis:
Diese Methode des Phar-Objekts funktioniert nur wenn die php.ini-Einstellung
phar.readonlyauf 0 gesetzt ist, sonst wird eine PharException geworfen.
For tar-based and phar-based phar archives, this method decompresses the entire archive.
For Zip-based phar archives, this method fails with an exception. The zlib extension must be enabled to decompress an archive compressed with gzip compression, and the bzip2 extension must be enabled in order to decompress an archive compressed with bzip2 compression. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.
In addition, this method automatically changes the file extension of the archive,
.phar
by default for phar archives, or .phar.tar for tar-based phar archives.
Alternatively, a file extension may be specified with the second
parameter.
Parameter-Liste
-
extension -
For decompressing, the default file extensions are
.pharand.phar.tar. Use this parameter to specify another file extension. Be aware that all executable phar archives must contain.pharin their filename.
Rückgabewerte
A Phar object is returned on success, and null on failure.
Fehler/Exceptions
Throws BadMethodCallException if the phar.readonly INI variable is on, the zlib extension is not available, or the bzip2 extension is not enabled.
