Question

Given 2 associative arrays:

$fruits  = array ( "d" => "lemon", "a" => "orange", "b" => "banana", "c" => "apple" );
$fruits2 = array ( "e" => "lemon", "f" => "apple",  "g" => "melon",  "h" => "apple" );

I would like to do something like:

for ( $n = count($fruits), $i = 0; $i < $n; $i++)
{
  $test = (bool) $fruits[$i] == $fruits2[$i];
}

This can not work as I am using associative array. What would be the best way to go to achieve that? (This loops is going to be ran intensity so I would like to keep it as light as possible)

EDIT to give more detail on what I am trying to do:

Here is a better example of what I am trying to achieve:

$array   = array ( 1,2,3,4,3,2 );
$array2  = array ( 9,6,3,4,3,2 );
$counts  = array_count_values( $words );
$counts2 = array_count_values( $words2 );

Given the arrays above I need to calculate which array as the highest duplicate integers. Imagine a poker game, comparing two hands that each contain duplicate cards, how to evaluate which set of duplicate (whether double, triple or quadruple ) as the highest value.

Answer 1

Got it working this way :

$n = count($fruits);
for ( $i = 0; $i < $n; $i++)
{
  $cur_vals_1 = each ($fruits);
  $cur_vals_2 = each ($fruits2);

  $sum1 += $cur_vals_1['key'] * $cur_vals_1['value'];

}
