PHP- combinations

[donatastommy]

 

$array1=["joe","bob"];
$array2=["tom","bill"];
$array3=["dan","mary"];

 

I want to print out every combination.. like (joe,tom,dan),( joe,tom,mary), only picking 1 from each array for each combination. and so on until there are no more combinations.  After this i want to post them onto 3 post forms on my website.. I know how to do that but I am stuck on this combination part.

 

Hard to explain.. hope you have understood..
