How to merge 3 arrays into one big array (same keys)

Question

I have 3 arrays called player1, player2, score:

Array ( [0] => player1 [1] => player1 [2] => player1 ) 
Array ( [0] => player2 [1] => player3 [2] => player2 ) 
Array ( [0] => 2-3 [1] => 1-3 [2] => 2-0 )

What I need is to join all arrays like this

[0] => player1, player2, 2-3
[1] => player1, player3, 1-3
[2] => player1, player2, 2-0

I am pretty new to PHP and I used the search bar before posting. Please do not down vote.

It'd be nice if you included the arrays as they are in your script to make for an easy copy and paste. — Michael, Mar 05 '13 at 12:20

try this :

array_unshift($array, null);
$res = call_user_func_array('array_map', $array);

echo "<pre>";
print_r($res);

EDIT : [Comment by 10now]

       $res = array_map(null, $player1, $player2, $score); 
       echo "<pre>"; 
       print_r($res);

That doesn't do what he wants. – Michael Mar 05 '13 at 12:20
Still doesn't do what he wants. Notice he has three arrays, not one? – Michael Mar 05 '13 at 12:28

Thanks guys. I get what I am looking for using the code you posted before and editing it to $res = array_map(null, $player1, $player2, $score); echo "
```
";
print_r($res);
```

Yeah...exactly, I thought it is a single array. :D – Prasanth Bendra Mar 05 '13 at 12:30

$array1 = array ( 'player1', 'player1', 'player1' );
$array2 = array ( 'player2', 'player3', 'player2' ) ;
$array3 = array ( '2-3', '1-3', '2-0' );

$mi = new MultipleIterator();
$mi->attachIterator(new ArrayIterator($array1));
$mi->attachIterator(new ArrayIterator($array2));
$mi->attachIterator(new ArrayIterator($array3));

$newArray = array();
foreach ( $mi as $value ) {
    $newArray[] = $value;
    list($team1, $team2, $result) = $value;
    echo $team1 , ' v ' , $team2, ' -> ', $result , '<br />';
}

var_dump($newArray);

$x=0;
foreach($arr1 as &$e){
    $e.=", $arr2[$x], $arr3[$x]";
    $x++;
}

This should leave the 1st array as the desired result.
