How do I check if multiple form inputs are empty at once with PHP?

So, I have some code that gets input from an HTML form via POST. I want to check if the input received is blank, but there are multiple form fields and just doing 

if(empty($_POST['forminput1'] or $_POST['forminput2'])){

isn't working, it correctly says there's an error if neither of them are filled (there are more fields, but I'm starting with this) but if just one is it says it's correct even if the other one is empty. Does anyone know how I can do this? I think it's because I'm using "OR" but I'm not sure how I'd get an "and/or" sort of thing (kind of new to PHP).

Try this :

 $forminput1 = $_POST['forminput1'];

if(!isset($forminput1) || trim($forminput1) == '')
{
echo "You did not fill out the required fields.";
}

This way you can inform user too which exact field is empty or they have not filled.

You have to type:

if(empty($_POST['forminput1']) || empty($_POST['forminput2'])){

the || means the 'or' operator you are talking about. The empty() function can only handle 1 variable: Reference. It returns TRUE if the variable is empty. If one formfield is empty, that function will return TRUE and your if statement will be TRUE because of the OR operator
