Using Types in PHP is one of the least used features, but very powerful features available in PHP. This is a feature that can save you and other developers a whole lot of stress (if you work with a team).
Of course, you can write function descriptions, but it becomes quite a daunting task to write function descriptions for all your functions and variables in a large project.
When someone else wants to use your function or even you want to use it after a couple of weeks later, it needs to check the function’s body to recognize which types you should pass to the function while using, if you don’t specify arguments types.
Ex:
function getItem(array $item) {
return allItems()[$item[0]];
}This will make sure that whatever is passed in here is the type needed. You can read more from www.php.net
