Running shell commands inside curl call in php

Question

I am using curl as like below. http://99.88.77.121/sample/curl.php

$ch = curl_init();
        $ip = "Some IP address";
        curl_setopt($ch, CURLOPT_URL, 'http://99.88.77.121/test/index.php');
        curl_setopt($ch, CURLOPT_POST, 1);

        $payload = json_encode(
                            array( 
                                'username' => 'abc', 
                                'password' => '1234'
                                )
                            );

        curl_setopt($ch, CURLOPT_POSTFIELDS,$payload);
        curl_setopt( $ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: $ip", "HTTP_X_FORWARDED_FOR: $ip"));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $result = curl_exec ($ch);

The above code sends the data to the Url.

I have code like below in my http://99.88.77.121/test/index.php

<?php 

  $fp = fopen('php://input', 'r');
  $rawData = stream_get_contents($fp);
  $data = json_decode($rawData);
  $username = $data->username;
  $password = $data->password;
  $projectName = "testFolder";
  chdir('../');
  //chdir($projectName);
  $command = "sudo chmod -R 777 ".$projectName;
  shell_exec($command);

?>

I am trying give full permission for testFolder using above code,

is chdir() and shel_exec() will work here? In my case its not working

If i run the index.php in browser, its working fine. but not from the curl call.

Can anyone look into it and update me your thoughts please.

Not answerable without guessing the error message. Look into the linked references to investigate. — mario, May 29 '19 at 12:55
@mario, what need to guess, did you understand my question? my question is completely different — Jafar Pinjar, May 29 '19 at 12:56
Yes, I think I did. No trace of error_reporting/debugging in your sample code though. — mario, May 29 '19 at 12:57
@mario, what info you need? have you got my question,? please read clearly then mark it as duplicate — Jafar Pinjar, May 29 '19 at 12:59
Imagine you are asking this question over the internet, and people do *not* have access to your setup. Then look and read through the duplicates to **narrow "not working" down** to something concrete, in particular either the curl call, or the shell_exec wrapper. — mario, May 29 '19 at 13:02
