You're missing the $ for ret_val on the return line. PHP thus understands the return value as a string, "ret_val", which would be taken as 0. Since all elements are now equal, the order of the elements in the array is undefined. Rabin Actually, PHP first looks for a constant named "ret_val", then it uses a string containing "ret_val". So, if there was a constant with that name, that value would have been used.
