PHP declaring empty arrays?

Question

I have to make a two-dimensional array based on the number of lets say car parts that is submitted on a form. Is it possible to declare an array of a certain size and THEN go back and fill it?

Answer 1

PHP arrays are dynamically allocated. There's no reason to create it ahead of time. Just start using the indexes as you need them:

$myNewVar[0] = 'data';
