stream_get_contents — Reads remainder of a stream into a string
$handle
[, int $maxlength = -1
[, int $offset = -1

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())
maxlength (integer)
The maximum bytes to read. Defaults to -1 (read all the remaining buffer).
offset (integer)
Seek to the specified offset before reading. If this number is negative, no seeking will occur and reading will start from the current position.

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);
}
