1.实现网站检测代码

/**

 * 网站状态检测
 */
header("Content-type: text/html; charset=utf-8");
include('functions.php');

$email_config = array(
    'smtp_host' => 'smtp.163.com',
    'smtp_port' => '25',
    'from_email' => '[e-mail]',
    'from_name' => 'LaiKinsan',
    'smtp_user' => 'yulongshuiji',
    'smtp_pass' => '',
    'reply_email' => '[e-mail]',
    'reply_name' => 'LaiKinsan',
    'email_arr' =>array(
        '[e-mail]',
        '[e-mail]',
    ),
    'test_email' => '[e-mail]',
);

check_status("");


//region 检测网站状态
function check_status($url)
{
    global $email_config;
    $ch = curl_init();
    if (!$ch) {
        die("没开curl模块功能");
    }
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 1); //获取http头信息
    curl_setopt($ch, CURLOPT_NOBODY, 1); //不返回html的body信息
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //返回数据流，不直接输出
    curl_setopt($ch, CURLOPT_TIMEOUT, 30); //超时时长，单位秒
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
    $string = $info['http_code'];

    if ($string === 200) {
        echo "ok";
    } else {
        foreach($email_config['email_arr'] as $k =>$v){
            $res = send_mail($v, '', '网站问题通知邮件', '这是一封通知邮件，如果收到了说明网站访问有问题，问题网址'.$url, '', $email_config);
            if ($res == 1) {
                echo "测试邮件已经发往你的邮箱";
            } else {
                echo "测试邮件发送失败";
            }
        }

    }
}
