How to get data using curl in php?

Question

I am trying to make a PHP api for this curl request

 curl 'http://xx.74.229.xxx:9200/snapdeal_electronics_mobiles_cat/_search' -d '{  "query": {  "match" : { "brand" : "Samsung" } } }'

While executing this in teminal I am getting response, but when I try to use it directly in PHP script , it's not working

   <?php
function httpGet($url)
{
   $ch = curl_init();

   curl_setopt($ch,CURLOPT_URL,$url);
   curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
//  curl_setopt($ch,CURLOPT_HEADER, false);

   $output=curl_exec($ch);

   curl_close($ch);
   return $output;
}

echo httpGet("http://xx.74.229.189:9200/snapdeal_electronics_mobiles_cat/_search' -d '{  "query": {  "match" : { "brand" : "Samsung" } } }");
?>

Kindly suggest some solution, it is a get request

The httpGet call has syntax errors. You could use exec, php.net/manual/en/intro.exec.php, and execute your original code or you could full translate it over to use the PHP CURL functionality. — chris85

It cant be a GET request because you include a POST body with the "-d" switch. — Daniel McAssey

You are creating the curl request incorrectly, it is also a POST request you are attempting not a GET as you include a POST body with the "-d" switch.

You need to seperate the URL from the POST body and pass 2 arguments, one for URL one for POST data like so:

<?php
function httpGet($url, $data)
{
   $ch = curl_init();

   curl_setopt($ch,CURLOPT_URL,$url);
   curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
//  curl_setopt($ch,CURLOPT_HEADER, false);

   curl_setopt($ch,CURLOPT_POSTFIELDS, $data); //POST data

   $output=curl_exec($ch);

   curl_close($ch);
   return $output;
}

echo httpGet("http://xx.74.229.189:9200/snapdeal_electronics_mobiles_cat/_search",'{  "query": {  "match" : { "brand" : "Samsung" } } }');
?>

Thanks @Daniel , this script is not giving me error but it's unable to respond me with correct output i.e, query is not executing

Without knowing how the request needs to be built or what type of response there is not much I can do.
