(PHP 5)
stream_get_contents — Reads remainder of a stream into a string
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 .
A stream resource (e.g. returned from fopen())
The maximum bytes to read. Defaults to -1 (read all the remaining buffer).
Seek to the specified offset before reading. Added in PHP 5.1.0.
Returns a string, or FALSE on failure.
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);
}
?>
