Examples

stream_set_timeout() example

php

<?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.
