(PHP 4 >= 4.0.4, PHP 5)

bzopen — Opens a bzip2 compressed file

### Description

resource bzopen ( mixed `$file` , string `$mode` )

bzopen() opens a bzip2 (.bz2) file for reading or writing.

### Parameters

`file`

  The name of the file to open, or an existing stream resource.

`mode`

  The modes 'r' (read), and 'w' (write) are supported. Everything else will cause bzopen() to return `FALSE`.

### Return Values

If the open fails, bzopen() returns `FALSE`, otherwise it returns a pointer to the newly opened file.

### Examples

`<?php
$file = "/tmp/foo.bz2";
$bz = bzopen($file, "r") or die("Couldn't open $file for reading");
bzclose($bz);
?>`
