Why choose array_key_exists over in_array in PHP?
🚐 array_key_exists is used to check if a key exists in an array, even for null values.
🚐 in_array is used to search for a value in an array but ignores keys.
🚐 Using array_key_exists for value searching is inefficient and vice versa.
🚐 array_key_exists ensures accuracy for null values, which isset fails to do.

These two functions seem similar, BUT they solve very different problems. In this lesson, uncover the key differences and see where each shines in real-world scenarios. Learn a trick that most developers overlook and improve your PHP array handling today!
