PHP中curl / file_put_contents / fscoketopen設定逾時時間比較小結

file_put_contents設定逾時時間

$opt = array(     'http'=>array(        'method'=>"GET",        'header'=>"Content-Type: text/html; charset=utf-8",        'timeout'=>2    )    );$context = stream_context_create($opt);file_get_contents("http://www.baidu.com", false, $context);

curl中的逾時設定：curl_setopt($ch, CURLOPT_TIMEOUT, 3)

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "http://www.baidu.com");curl_setopt($ch, CURLOPT_TIMEOUT, 1);curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);$data = curl_exec($ch);curl_close($ch);

fscoketopen 逾時

function request($host, $uri, $timeout = 3, $port = 80){    $fp = fsockopen ( $host, 80, $errno, $errstr, $timeout );    if (! $fp) {        echo "$errstr ($errno)
\n";        exit;    } else {        $data = '';        stream_set_timeout ( $fp, $timeout ); //#        $out = "GET {$uri} HTTP/1.1\r\n";        $out .= "Host: {$host}\r\n";        $out .= "Connection: Close\r\n\r\n";        fwrite ( $fp, $out );        while ( ! feof ( $fp ) ) {            $data .= fgets ( $fp, 128 );        }        fclose ( $fp );        return $data;    }    }echo request('www.scutephp.com', '/siqi');
