The bzip2 functions are used to transparently read and write bzip2 (.bz2) compressed files.
This module uses the functions of the bzip2 library by Julian Seward. This module requires bzip2/libbzip2 version >= 1.0.x.
Bzip2 support in PHP is not enabled by default. You will
need to use the
configuration option when compiling PHP to enable bzip2 support.
This extension has no configuration directives defined in php.ini.
This extension defines one resource type: a file pointer identifying the bz2-file to work on.
This extension has no constants defined.
This example opens a temporary file and writes a test string to it, then prints out the contents of the file.
