Phar::decompress

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

Phar::decompress — Decompresses the entire Phar archive

Beschreibung

public Phar::decompress(?string $extension = null): ?Phar

Hinweis:
Diese Methode des Phar-Objekts funktioniert nur wenn die php.ini-Einstellung phar.readonly auf 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 .phar and .phar.tar. Use this parameter to specify another file extension. Be aware that all executable phar archives must contain .phar in 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.

Changelog

Version	Beschreibung
8.0.0	`extension` is now nullable.

Beispiel #1 A Phar::decompress() example

<?php
$p = new Phar('/path/to/my.phar', 0, 'my.phar.gz');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p3 = $p2->decompress(); // creates /path/to/my.phar
?>

decompress() will truncate any part of the filename after the first period, as it assumes it's part of the extension. For example, if your PharData archive is named "views-3.x-3.13.tar.gz", calling decompress on it will create a tar file named "views-3.tar". See https://bugs.php.net/bug.php?id=58852
