stream_get_contents

Reads remainder of a stream into a string

Description

stringfalse stream_get_contents(resource $stream, intnull $length = null, int $offset = -1)

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 length bytes and starting at the specified offset.

Parameters

stream (resource)

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

length (int)

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

offset (int)

Seek to the specified offset before reading. If this number is negative, no seeking will occur and reading will start from the current position.

Return Values

Returns a string or false on failure.

Changelog

Version Description
8.0.0 length is now nullable.

Examples

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);
}

?>

Notes

Note: This function is binary-safe.

Note:

When specifying a length value other than null, this function will immediately allocate an internal buffer of that size even if the actual contents are significantly shorter.
