What is the difference between using count() and sizeof() to get the length of an array in PHP?

When trying to get the length of an array in PHP, you can use either the count() function or the sizeof() function. Both functions return the number of elements in an array. The main difference is that count() is a language construct, while sizeof() is an alias of count() and behaves in the same way. It is recommended to use count() for consistency and readability.

// Using count() to get the length of an array
$array = [1, 2, 3, 4, 5];
$length = count($array);
echo $length;
