PHP 8.1.24 Released!


This module enables you to transparently read and write gzip (.gz) compressed files, through versions of most of the filesystem functions which work with gzip-compressed files (and uncompressed files, too, but not with sockets).


PHP comes with a fopen-wrapper for .gz-files. More information is available in the section about zlib://.

This introduction is incomplete because it lacks the information that the module can be used to use HTTP gzip compression with the 'zlib.output_compression' and 'zlib.output_compression_level' configuration settings.

Please be aware that cross-site scripting should be disabled when using HTTP compression because of possible BREACH attacks.
