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;
    }

}
