readgzfile — Output a gz-file

说明

function readgzfile(string $filename, bool $use_include_path = false): 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

When set to true the include_path will be used to determine which file to open.

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。

更新日志

版本 说明
8.5.0 use_include_path is now of type bool. Previously, it was of type int.
8.5.0 The default stream context (see stream_context_set_default()) is now used when opening the file. Previously, it was ignored.
