PHP - Debugging Curl

Closed 3 years ago.
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.
