What are some best practices for determining the number of elements in an array in PHP?

Determining the number of elements in an array in PHP can be done using the `count()` function, which returns the number of elements in an array. It is a best practice to use this function instead of relying on other methods like `sizeof()` or `count($array, COUNT_RECURSIVE)` for simplicity and consistency. 

// Example array
$array = [1, 2, 3, 4, 5];

// Determine the number of elements in the array
$numberOfElements = count($array);

echo $numberOfElements; // Output: 5
