[RESOLVED] trying to combine two arrays as key value pairs php4

[ade234uk]

I am trying to combine two arrays in php4 as key value pairs. I found an example that does the job, however array_combine does not work in php4.

How do I combine to arrays in php4 as key value pairs.

$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);

print_r($c);

function my_array_combine($a, $b)
{
   $result = array();
   while(($key = each($a)) && ($val = each($b)))
   {
      $result[$key[1]] = $val[1];
   }
   return($result);
}

PS: If you want a more robust version which emulates the error results/notices of the PHP5 function:

function my_array_combine($a, $b)
{
   if(!is_array($a) or !is_array($b) or !count($a) or !count($b))
   {
      user_error(__FUNCTION__ . ': non-array or empty array supplied as parameter');
      return(FALSE);
   }
   if(count($a) != count($b))
   {
      user_error(__FUNCTION__ . ': empty array supplied as parameter');
   }
   $result = array();
   while(($key = each($a)) && ($val = each($b)))
   {
      $result[$key[1]] = $val[1];
   }
   return($result);
}
