# stream_set_timeout

(PHP 4 >= 4.3.0, PHP 5)

stream_set_timeout — Set timeout period on a stream

### Description

bool stream_set_timeout ( resource `$stream` , int `$seconds` [, int `$microseconds` ] )

Sets the timeout value on `stream` , expressed in the sum of `seconds` and `microseconds` . Returns `TRUE` on success or `FALSE` on failure.

When the stream times out, the 'timed_out' key of the array returned by stream_get_meta_data() is set to `TRUE`, although no error/warning is generated.

Example#1 stream_set_timeout() example

`<?php
$fp = fsockopen("www.example.com", 80);
if (!$fp) {
echo "Unable to open\n";
} else {
fwrite($fp, "GET / HTTP/1.0\r\n\r\n");
stream_set_timeout($fp, 2);
$res = fread($fp, 2000);
$info = stream_get_meta_data($fp);
fclose($fp);
if ($info['timed_out']) {
echo 'Connection timed out!';
} else {
echo $res;
}
}
?>`

> Note: As of PHP 4.3, this function can (potentially) work on any kind of stream. In PHP 4.3, socket based streams are still the only kind supported in the PHP core, although streams from other extensions may support this function.

> Note: This function doesn't work with advanced operations like stream_socket_recvfrom(), use stream_select() with timeout parameter instead.

This function was previously called as set_socket_timeout() and later socket_set_timeout() but this usage is deprecated.
