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 --with-bz2[=DIR] configuration option when compiling PHP to enable bzip2 support.
This extension defines one resource type: a file pointer identifying the bz2-file to work on.
This example opens a temporary file and writes a test string to it, then prints out the contents of the file.
