I still didn’t understand OOP for PHP this morning, but I decided to take the plunge and start writing a class for a website navigation interface, using a series of arrays to print out a tabbed multilevel menu. And as I went along, suddenly all the concepts fell into place, and I understood! Learning by doing really is the way to go.
Onward, then, to the next struggle: making practical use of multidimensional associative arrays without losing the very essence of my being in the convoluted, obfuscated mazes of nested values and variables.
