Server-side PHP generates curl command line

Record the request to the log. In order to facilitate subsequent troubleshooting, call a method in PHP to record the curl string to facilitate reproducing the request.

<?php

function getCurlCommand()
{
    try {
        if (php_sapi_name() == &#39;error cli&#39;){

        }
        $curlCommand = &#39;curl &#39;;

        return $curlCommand;
    } catch (Exception $e) {
        return $e->getMessage();

echo getCurlCommand();

eg:

curl “http://localhost/other/serverInfo.php?dd=ddd” -H “Host:localhost” -H “Connection:keep-alive”
 -H “Cache-Control:max-age=0” -H “Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8”
