readgzfile

(PHP 4, PHP 5, PHP 7)

readgzfile — Output a gz-file

说明

readgzfile ( string $filename [, int $use_include_path = 0 ] ) : int

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.

参数

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.

返回值

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.
