PharData::decompress

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

PharData::decompress — Decompresses the entire Phar archive

说明

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.

参数

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.

返回值

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

错误／异常

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

更新日志

版本 说明
8.0.0 extension is now nullable.
