(PHP 4 >= 4.3.0, PHP 5)

stream_set_timeout -- Set timeout period on a stream

Описание

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

Sets the timeout value on stream, expressed in the sum of seconds and microseconds. Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

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.

<?php
$fp = fsockopen("www..com", 80);
if (!$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;
    }

}
?>

Замечание: 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 /component/search/f=

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

See also fsockopen() and fopen().
