What is CURL?
cURL is a PHP extension, that allows us to receive and send information via the URL syntax. By doing so, cURL makes it easy to communicate between different websites and domains.

<?php

function _is_curl_installed() {
    if  (in_array  ('curl', get_loaded_extensions())) {
        return true;
    }
    else {
        return false;
    }
}

// Ouput text to user based on test
if (_is_curl_installed()) {
  echo "cURL is <span style=\"color:blue\">installed</span> on this server <br><br><br>";
} else {
  echo "cURL is NOT <span style=\"color:red\">installed</span> on this server";
}


function isExtensionLoaded($extension_name){
    return extension_loaded($extension_name);
}
echo isExtensionLoaded('curl');
echo isExtensionLoaded('gd');



echo " <br><br><br>";

function nxs_cURLTest($url, $msg, $testText){  
  $ch = curl_init(); 
  curl_setopt($ch, CURLOPT_URL, $url); 
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.73 Safari/537.36"); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
  $response = curl_exec($ch); 
  $errmsg = curl_error($ch); 
  $cInfo = curl_getinfo($ch); 
  curl_close($ch); 
  echo "Testing ... ".$url." - ".$cInfo['url']."<br />";
  if (stripos($response, $testText)!==false) 
    echo "....".$msg." - OK<br />";

    print_r($errmsg); 
    print_r($cInfo); 
    print_r(htmlentities($response)); 
    echo "</pre>There is a problem with cURL. You need to contact your server admin or hosting provider.";
