在API中捕获调用

Question

I have a page wherein it will serve as a for that is connected to my API.php. In this page I used Curl PUT verb and passed the URL and the data I need to pass which is in the form of an array.

I tried catching the response in the side of the API but to no avail.

Here's my code.

The URL they need to populate or I think this is the API

http://localhost/sample/index.php/2/users/mil/milastname/09876543212

Legend:

Sample - is the folder where I stored my index.php

2 - is the action. In this case 2 stands for PUT verb.

users - is the table in the database which I want to update.

mil - is my firstname

milastname - is my lastname

09876543212 - is my mobile

MY FORMS

index.php

$request = explode('/', trim($_SERVER['PATH_INFO'],'/'));


if ($request[0] == 2) {
$data = array(
  "table" => $request[1],
  "fname" => $request[2],
  "lname" => $request[3],
  "cntct" => $request[4]
);

$url_send ="http://localhost/api.php";
$str_data = json_encode($data);
$post_elements = array('data'=>$data);

if ($request[0] == 2) {
  put($url_send, $post_elements);
  echo put($url_send, $post_elements);
}


function put($url, $fields)
{

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query($fields));

echo curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query($fields));

$response = curl_exec($ch);

curl_close ($ch);

return $response;
}

Here's my API.php

if ($method == 'PUT') {
$data = preg_replace('/[^a-z0-9_]+/i','',array_shift($_POST));
echo $data;
die();
}

switch ($method) {
case 'PUT':
  $sql = "update `$table` set $set where id=$key"; break;
case 'POST':
  $sql = "insert into `$table` (user_fname, user_lname, user_contact) values ('$fname', '$lname', '$cntct')"; break;
case 'DELETE':
  $sql = "delete `$table` where id=$key"; break;
}

$result = mysqli_query($link,$sql);

In the part of if ($method == 'PUT')

I tried inserting an echo and a die to stop the process to that I can see the array So I can arrange the update query in my method case update. But it returns no result.

Thanks for the help and sorry for the long post. Need to detail it so that I can explain my question clearly.

Thanks.
