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...

Subject: [PHP] Tough comparison problem.
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.
Any help is greatly appreciated!
