call multiple url sequentially with php curl

Question

How to call more than one url in curl using php and must be executed sequentially one after the another..

Below is my php code

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL,"http://192.168.1.220/cgi-bin/handle_login.tcl");
   curl_setopt($ch, CURLOPT_POST, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS,
        "user=admin&pw=admin&submit=Login");            
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   $response = curl_exec($ch);
   echo "$response";
   curl_close ($ch);


  $ch1= curl_init();
  curl_setopt($ch1, CURLOPT_URL,"http://192.168.1.220/cgi-bin/controller.tcl?sid=$response&type=inverter&inverter=318002N463");
  curl_setopt($ch1, CURLOPT_HTTPGET, TRUE);         
  curl_setopt($ch1, CURLOPT_RETURNTRANSFER, true);
  $response1= curl_exec($ch1);
  curl_close ($ch1);


  $ch2= curl_init();
  curl_setopt($ch2, CURLOPT_URL,"http://192.168.1.220/cgi-bin/overview.tcl?sid=$response&menuParentId=3");
  curl_setopt($ch2, CURLOPT_HTTPGET, TRUE);         
  curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);
  $response2= curl_exec($ch2);
  curl_close($ch2);

Only my first curl command is executed remaining is not being executed

You can define a function which accepts URL, with this you can prevent rewriting code everytime, or you can use multi curl but make sure it is not sequential — Sahil Gulati

@Pardeep For that you can pass multiple parameter one as URL and other as Method — Sahil Gulati

For sequential curl request you can define function and use it like this. If you are not concerned about sequential request you can use multi curl for that.

<?php

ini_set('display_errors', 1);


$response=curl_request("http://192.168.1.220/cgi-bin/handle_login.tcl","POST","user=admin&pw=admin&submit=Login");
curl_request("http://192.168.1.220/cgi-bin/controller.tcl?sid=$response&type=inverter&inverter=318002N463");
curl_request("http://192.168.1.220/cgi-bin/overview.tcl?sid=$response&menuParentId=3");

function curl_request($url,$method="GET",$postFields="")
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    if($method=="POST")
    {
        curl_setopt($ch, CURLOPT_POST, 1);       
        curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
    }
    else
    {
        curl_setopt($ch, CURLOPT_HTTPGET, TRUE);
    }
    $response = curl_exec($ch);
    echo "$response";
    return $response;

}
