Examples
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;
}
}
?>
Notes
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.
