RE: [PHP] Tough comparison problem.

PHP3? too bad... PHP4 has a magic array_intersect (php.net/array_intersect) try to see php.net/arrays you might find what suits you. you're double loop will slow your application dramatically. but if it's the only way...

I've got two functions that return data in an array. I need to compare the individual elements of one array against the elements of another, and do something within an if-else statement. I'm using php3, so I don't have an actual "foreach" loop to pick out the array elements. Instead, I use: while(list(, $element)=each($array)){ Basically, here's what I need to do: Pull element 1 out of array 1, Compare it to all elements of array 2, Do something (if-else) based on the results of that comparison, Pull element 2 out of array 1, Compare it to all elements of array 2, and so on until all elements of array 1 have been compared to all elements of array 2.
