2 dimensional trouble

fowler

Hi, Im having a hard time with 2 dimensional arrays.

I want to merge two 2 dimensional arrays (or add a two dimensional element to an already existing 2 dimentional array), but I must be able to maintain the location of all of the elements, like:

array1(
[1]=>[1][2]
[3]=>[1][2]
)

and then adding another 2 dimensional array to the first with a specific location:

array2(
[23]=>[1][2]
)
+
array1(
[1]=>[1][2]
[3]=>[1][2]

)

array3(
[1]=>[1][2]
[3]=>[1][2]
[23]=>[1][2]
)

I have no idea how to do this, I suspect that the solution is very simple and I apriciate all the help I can get. Thanks in advance.

Have you tried [man]array_merge[/man]

[edit]After testing I didnt think it would work 100% to start with the 23 index will be removed and replaced as 3 so its

array(
1 => array(1, 2),
2 => array(1,2),
3 => array(1,3)
);

If the 3rd index is array(23 => array(1,3))

since [man]array_merge[/man] will mess up those keys since they are numbers, heres my version

<?php

$arr1 = array( "1"=>array("1", "2"), "3"=>array("3", "4") );
$arr2 = array( "23"=>array("5","6") );

$arr3 = my_array_merge($arr1, $arr2);

print_r($arr3);

function my_array_merge()
{
	if (func_num_args() == 0) return array();

$arr3 = array();

foreach(func_get_args() as $key=>$value) {
	if (!is_array($value)) continue;

	foreach($value as $thekey=>$thevalue) {
	  $arr3[$thekey] = $thevalue;
	}
}

return $arr3;
}

?>
