PharFileInfo::decompress

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

PharFileInfo::decompress — Decompresses the current Phar entry within the phar

Açıklama

public PharFileInfo::decompress(): true

This method decompresses the file inside the Phar archive. Depending on how the file is compressed, the bzip2 or zlib extensions must be enabled to take advantage of this feature. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction.

Dönen Değerler

Daima true döndürür.

Hatalar/İstisnalar

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