PHP Curl Example with Error Checking

php-curl.php

<?php

//initialize
$ch = curl_init();

// 2. set the options, including the url
curl_setopt($ch, CURLOPT_URL, "https://api.pingdom.com/api/2.0/traceroute?host=techslides.com");
curl_setopt($ch, CURLOPT_HTTPHEADER, array("App-Key: YOUR-KEY-HERE"));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);

//execute
$output = curl_exec($ch);

if ($output === FALSE) {
  echo "cURL Error: " . curl_error($ch);
} else {
	var_dump($output);
}

//free up the curl handle
curl_close($ch);

?>

This will not work, here is the correct version for Pingdom API.
