Parse.com request using PHP SDK

I am trying to query Parse.com using the new PHP SDK. I've installed everything I need. I have a problem with the request.

link: [ https://www.parse.com/docs/php_guide#queries]

I tried using this:

 require 'vendor/autoload.php';

 use Parse\ParseClient;
 use Parse\ParseObject;

 ParseClient::initialize('secret1','secret2', 'secret3');


 $query = new ParseQuery("TableName");
 $query->equalTo("email", "email@me.com");
 $results = $query->find();
 echo "Successfully retrieved " . count($results) . " scores.");

      

        
        
        
      

    

Any help would be greatly appreciated! Thank!!!!

SOLVING with help from William George! Here is my updated code:

 require 'vendor/autoload.php';

 use Parse\ParseClient;
 use Parse\ParseObject;
 use Parse\ParseQuery;

 ParseClient::initialize('secret1','secret2', 'secret3');

 try{
 $query = new ParseQuery("TableName");
 $query->equalTo("email", "email@me.com");
 $results = $query->find();
 echo "Successfully retrieved " . count($results) . " scores.";
 } catch (Exception $e){
    echo $e->getMessage();
 }
