Reading values from cURL POST request - php

Question

I am trying to make a POST request using cURL in PHP. I have the code to make the POST request (from index.php) and I believe it is correct.
The next part is the API layer (api.php) which needs to extract the data from the POST request and this is where I am having issues. In the code, I am trying to read the value of the parameter q that I have passed using index.php.
Here's the code for both the files.
index.php
<?php
$handle = curl_init();
curl_setopt_array(
$handle,
array(
CURLOPT_URL => 'http://localhost:8888/restAPI/api.php',
'q' => 'getCompanyId',
'post_fields' => 'q=getCompanyId',
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => array(
'q' => 'getCompanyId'
),
CURLOPT_RETURNTRANSFER => true
)
);
$response = curl_exec($handle);
curl_close($handle);
?>
api.php
<?php
require_once("Rest.inc.php");
class API extends REST {
public function processApi() {
$func = $_REQUEST['q'];
if((int)method_exists($this,$func) > 0){
$this->$func();
}
else{
$this->response('',404);
// If the method not exist with in this class, response would be "Page not found".
}
}
public function getCompanyId(){
$dbhost = 'localhost:8888';
$conn = mysql_connect($dbhost, 'root', 'root');
if (! $conn) {
die('Could not connect - ' . mysql_error());
}
$sql = 'SELECT companyId FROM Companies';
mysql_select_db('IRSocialBackend');
$executeSql = mysql_query($sql);
while($data = mysql_fetch_array($executeSql)){
echo $data['companyId'];
}
}
}
//echo "here";
$api = new API;
$api -> processApi();
?>

Just a side note: your API is not RESTFUL. REST is not a matter of "making HTTP requests". Read up on it!
First mistake:
array(
CURLOPT_URL => 'http://localhost:8888/restAPI/api.php',
'q' => 'getCompanyId',
'post_fields' => 'q=getCompanyId',
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => array(
'q' => 'getCompanyId'
),
CURLOPT_RETURNTRANSFER => true
)
Random "q" and "post_fields" is definitely not how you add fields to curlopt.
In api.php, you assign the following:
$dbhost = 'localhost:8888';
$conn = mysql_connect($dbhost, 'root', 'root');
I thought localhost:8888 was your webserver? localhost:3306 would be your MySQL server if it is on a default port.
The rest is hard to debug without knowing your table/DB structure.
