Looks like your syntax for $product = $products[$product_id]; isn't quite right.

What type of array is it supposed to be?

Indexed arrays - Arrays with a numeric index Associative arrays - Arrays with named keys Multidimensional arrays - Arrays containing one or more arrays

—

try $product = $products => [$product_id];
