Question

i have this situation $test:

               $months = Array
                    (
                        [3] => 7.56
                        [7] => 11.94
                        [1] => 6.90
                        [17] => 6.90
                        [6] => 6.90
                        [4] => 19.50
                    )
               $total = Array
                    (
                        [31] => 10
                        [17] => 4
                    )

i would like to combine them in such way that ill get $x = array([17] => 6.90)

basically put together the values from $months and the keys from $total where the $months.key = $total.key

any ideas?

thanks

Answer 1

foreach ($total as $k => $v) if (isset($months[$k])) $x[$k] = $months[$k];
