Unset empty elements in Array

It is quite easier to unset empty element(s) in an array in php. Following code will do the work.

     //this is a test array
     $testArr = array(1 => "First", 2 => "", 3 => "Third", 4 => "", 5 =>"Fifth");
     //loop through the array and remove empty elements
     foreach($testArr as $key => $value) {
         if(empty($value)) {
            unset($testArr[$key]);
         }
     }
     //view the array with empty elements removed
     print_r($testArr);
?>
