php - How to get the delay ms of the website

Question

I have never seen this before. The boss suddenly said that he would add a delay speed of ms to display the website on the page. I haven't found any useful information after Baidu for a long time. I would like to ask some experts to tell me how to achieve it.

Answer 1

if (strcasecmp(PHP_OS, 'WINNT') === 0) {
    // Windows 服务器下
    $pingresult = exec("ping -n 1 {$address}", $outcome, $status);
} elseif (strcasecmp(PHP_OS, 'Linux') === 0) {
    // Linux 服务器下
    $pingresult = exec("ping -c 1 {$address}", $outcome, $status);
}
