[RESOLVED] 2D Array Help

[shawjames]

I have three arrays that I want to combine into one 2D array.

Each array has a code/value pair. The codes are the same in each array, but all codes may not be present in each array.

Each array is:

$array1 = array ("a1" => "22", "c2" => "17", "d1" => "5", "e3" => "101");
$array2 = array ("b1" => "4", "f1" => "6", "g1" => "3", "h1" => "10");
$array3 = array ("c2" => "8", "d1" => "9", "e3" => "1", "g1" => "2");

I want to combine these into one 2D array, that would look like this:

$array2D = array(
"a1" => array(22,0,0),
"b1" => array(0,4,0),
"c2" => array(17,0,8),
"d1" => array(5,0,9),
"e3" => array(101,0,1),
"f1" => array(0,6,0),
"g1" => array(0,3,2)
);

I tried

$array2D = array_merge_recursive($array1, $array2, $array3);

But this does not put the values in the correct position, it puts the values in the first position... For example, it puts:

[c2] => Array
    (
        [0] => 17
        [1] => 8
    )

but it should be:

[c2] => Array
    (
        [0] => 17
        [1] => 0
        [2] => 8
    )

Any ideas?

$src[0] = array ("a1" => "22", "c2" => "17", "d1" => "5", "e3" => "101");
$src[1] = array ("b1" => "4", "f1" => "6", "g1" => "3", "h1" => "10");
$src[2] = array ("c2" => "8", "d1" => "9", "e3" => "1", "g1" => "2");

for ($i = 0; $i < count($src); $i++)
{
foreach ($src[$i] as $name => $value)
{
if (!isset($dst[$name])) $dst[$name] = array(0, 0, 0);
$dst[$name][$i] = $value;
}
}

print_r($dst);

O, and the result was:

Array (
[a1] => Array ( [0] => 22 [1] => 0 [2] => 0 )
[c2] => Array ( [0] => 17 [1] => 0 [2] => 8 )
[d1] => Array ( [0] => 5 [1] => 0 [2] => 9 )
[e3] => Array ( [0] => 101 [1] => 0 [2] => 1 )
[b1] => Array ( [0] => 0 [1] => 4 [2] => 0 )
[f1] => Array ( [0] => 0 [1] => 6 [2] => 0 )
[g1] => Array ( [0] => 0 [1] => 3 [2] => 2 )
[h1] => Array ( [0] => 0 [1] => 10 [2] => 0 )
)

Thanks!

This works, the arrays are actually sort of big (50,000 each), but should be fine!
