What's the best way of checking if an object property in php is undefined?

Question

@RiggsFolly I know. But that "code" means there is a close reason. Asking the same question correct is better. Although in this case it didn't make any difference. — Andreas, Feb 07 '19 at 11:29

You can use is_null Or !isset($object)

Example :

I want to check if the input is undefined. So, I can show errors.

if (!isset($_POST['myInput'])) { echo "error"; } else { // do the code }
