here's some strange behavior... if you run: $arrayvar = array(); $regvar = 'arrayvar["idx"]'; $$regvar = 'Hello!'; then $regvar is 'arrayvar["idx"]', $$regvar is 'Hello!', and ${arrayvar["idx"]} is "Hello!", but $arrayvar["idx"] is empty! SO, what's actually happening is that PHP has assigned a variable called 'arrayvar["idx"]', but (because it was assigned in a variable variable) hasn't parsed it for brackets in order to make it an array! And when you try to use the variable directly, it DOES parse for the brackets, therefore making the variable you intended to set different from the one you actually set. http://www.php.net/manual/en/language.variables.variable.php
