Phar::decompress

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

Phar::decompressDecompresses the entire Phar archive

Descrizione

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

Nota:

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.

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.

Elenco dei parametri

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.

Valori restituiti

A Phar object is returned on success, and null on failure.

Errori/Eccezioni

Throws BadMethodCallException if the phar.readonly INI variable is on, the zlib extension is not available, or the bzip2 extension is not enabled.

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
