Checking if all the array items are empty PHP

Question

I'm adding an array of items from a form and if all of them are empty, I want to perform some validation and add to an error string. So I have: ``` $array = array( 'RequestID' => $_POST["RequestID"], 'ClientName' => $_POST["ClientName"], 'Username' => $_POST["Username"], 'RequestAssignee' => $_POST["RequestAssignee"], 'Status' => $_POST["Status"], 'Priority' => $_POST["Priority"] ); ``` And then if all of the array elements are empty perform: ``` $error_str .= '

'; ```
