I have an array of two objects that I have serialize. These objects are products. Each element of this array is an object(product) that contains an array of another objects (projects about a product). In a form, after the unserialisation, I want to print all of these products in a <select> but I can't access to them. I need to access to each of them by the index in the array but I can't. Please can somebody help me. Thanks
