# readgzfile

(PHP 4, PHP 5)

readgzfile — Output a gz-file

### Description

int readgzfile ( string `$filename` [, int `$use_include_path` ] )

Reads a file, decompresses it and writes it to standard output.

readgzfile() can be used to read a file which is not in gzip format; in this case readgzfile() will directly read from the file without decompression.

### Parameters

`filename`

  The file name. This file will be opened from the filesystem and its contents written to standard output.

`use_include_path`

  You can set this optional parameter to 1, if you want to search for the file in the include_path too.

### Return Values

Returns the number of (uncompressed) bytes read from the file. If an error occurs, `FALSE` is returned and unless the function was called as @readgzfile, an error message is printed.
