When should I use is_null and empty in PHP?
When should I use is_null and empty in PHP?
🚐 is_null is used to check if a variable is explicitly set to null.
🚐 empty checks if a variable is either null, false, an empty string, or an empty array.
🚐 empty is more versatile when dealing with different types of empty values like an empty string or 0.
🚐 is_null is best for checking if a variable is intentionally unset or has no value, not for checking if it’s empty.
In PHP, is_null and empty are both used to check variables, but they serve different purposes. When checking if a variable is not set or is empty, each function behaves uniquely. But which one is better for your use case? In this lesson, we will dive into the subtle differences between is_null and empty to understand when and why you should use one over the other.
