*	getDA( $urlToDA )
----------------------->

Description:
	- Function prepared to return the Domain Authority (DA) as a rounded integer that measures the MOZ platform.

Parameters:
	- $urlToDA:		String type URL --> xxx.com, www.xxx.com, etc.

Return:
	- A rounded integer corresponding to the DA of that URL according to MOZ.

To consider:
  - Due to the limitations of the free account, a delay of 11 seconds between call and call must be put.
  - In addition to the DA, $content array, returns other data that can be observed with a print_r($ content); at line 65.

function getDA( $urlToDA ){
	// Get your access id and secret key here: https://moz.com/products/api/keys
	$accessID = "your-MOZ-accessID";
	$secretKey = "your-MOZ-secretKey";
	// Set your expires times for several minutes into the future.
	// An expires time excessively far in the future will not be honored by the Mozscape API.
	$expires = time() + 300;
	// Put each parameter on a new line.
	$stringToSign = $accessID."\n".$expires;
	// Get the "raw" or binary output of the hmac hash.
	$binarySignature = hash_hmac('sha1', $stringToSign, $secretKey, true);
	// Base64-encode it and then url-encode that.
	$urlSafeSignature = urlencode(base64_encode($binarySignature));
	// Specify the URL that you want link metrics for.
	$objectURL = $urlToDA;
	// Add up all the bit flags you want returned.
	// Learn more here: https://moz.com/help/guides/moz-api/mozscape/api-reference/url-metrics
	$cols = "103079215108";
	// Put it all together and you get your request URL.
	// This example uses the Mozscape URL Metrics API.
	$requestUrl = "http://lsapi.seomoz.com/linkscape/url-metrics/".urlencode($objectURL)."?Cols=".$cols."&AccessID=".$accessID."&Expires=".$expires."&Signature=".$urlSafeSignature;
	// Use Curl to send off your request.
	$options = array(
		CURLOPT_RETURNTRANSFER => true
		);
	$ch = curl_init($requestUrl);
	curl_setopt_array($ch, $options);
	$content = curl_exec($ch);
	curl_close($ch);
  
	//print_r($content);	// Uncommnet to check full results

	$array1 = explode(',', $content);
	$array2 = explode(":", $array1[0]);

	sleep(11);	// We waited 11 seconds (delay required for the Moz API with free account)

	return (int)round($array2[1]);		// We return the DA as rounded INT
