PharData::decompress

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

PharData::decompress — Decompresses the entire Phar archive

Descrição

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

For tar-based archives, this method decompresses the entire archive.

For Zip-based 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.

In addition, this method automatically renames the file extension of the archive, .tar by default. Alternatively, a file extension may be specified with the extension parameter.

Parâmetros

extension: For decompressing, the default file extension is .tar. Use this parameter to specify another file extension. Be aware that only executable archives can contain .phar in their filename.

Valor Retornado

A PharData object is returned on success, or null on failure.

Erros/Exceções

Throws BadMethodCallException if the zlib extension is not available, or the bzip2 extension is not enabled.

Registro de Alterações

Versão	Descrição
8.0.0	`extension` is now nullable.

If filename contains multiple dots(.), you can preserve other parts by following code (example1).

Example #1 (Expected)
<?php
$filename = "abc.xyz.tar.gz";
$p = new PharData($filename);
$exts = explode('.', $filename);
array_shift($exts);
array_pop($exts);
$ext = implode('.', $exts);
$p->decompress($ext); # result filename: abc.xyz.tar
?>

Example #2 (might be unexpected)
<?php
$filename = "abc.xyz.tar.gz";
$p = new PharData($filename);
$p->decompress($filename); # result filename: abc.tar; xyz is truncated accidentally.
?>
