PHP 获取网站 HTTP 状态码、响应时间和状态信息代码示例

php/nfunction get_http_code($url='localhost', $port=80, $fsock_timeout=10){/n set_time_limit(0);/n ignore_user_abort(true);/n/n // 记录开始时间/n list($usec, $sec) = explode(' ', microtime(true));/n $timer['start'] = (float)$usec + (float)$sec;/n/n // 校验URL/n if(!preg_match('/^https?://///i', $url)){/n $url = 'http://'.$url;/n }/n // 支持HTTPS/n if(preg_match('/^https://///i', $url)){/n $port = 443;/n }/n/n // 解析URL/n $urlinfo = parse_url($url);/n if(empty($urlinfo['path'])){/n $urlinfo['path'] = '/';/n }/n $host = $urlinfo['host'];/n $uri = $urlinfo['path'] .
