readgzfile — Output a gz-file

说明

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

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 on success, 或者在失败时返回 false

错误／异常

失败时抛出E_WARNING警告。
