PHP5中文手册·Reads remainder of a stream into a string -- 追寻梦想＞编程乐园＞PHP 编程

Description

string stream_get_contents ( resource $handle [, int $maxlength [, int $offset ]] )

Identical to file_get_contents(), except that stream_get_contents() operates on an already open stream resource and returns the remaining contents in a string, up to maxlength bytes and starting at the specified offset .

参数

handle (resource): A stream resource (e.g. returned from fopen())
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.

范例

Example#1 stream_get_contents() example


<?php

if ($stream = fopen('http://www.example.com', 'r')) {
    // print all the page starting at the offset 10
    echo stream_get_contents($stream, -1, 10);

    fclose($stream);
}


if ($stream = fopen('http://www.example.net', 'r')) {
    // print the first 5 bytes
    echo stream_get_contents($stream, 5);

    fclose($stream);
}

?>
