Use empty() for arrays only,
Use isset() for nullable objects (not datatypes) only,
Use array_key_exists() for checking if the element exists in the array.
Also, don’t use empty() on Laravel Collections, use the built in isEmpty() methods because empty() will always be false.
For almost the same reason don’t use isset()
Isset(0) is false. Use !== null.
