stream_get_contents

(PHP 5)

stream_get_contents -- Reads remainder of a stream into a string

Description

maxlength (integer)

The maximum bytes to read. Defaults to -1 (read all the remaining buffer).

offset (integer)

Seek to the specified offset before reading. Added in PHP 5.1.0.

返回值

Returns a string, or FALSE on failure.
