Two arrays in one array PHP

I have one question: How can I push two arrays into one array, so scheme should look like:

array1 = array("element1", element2, "element3");
array2 = array("element4", element5, "element6");

[0] => FinalArray
        (
            [0] => array1[] => 
                      (
                            [0] = element1
                            [1] = element2
                            [2] = element3
                      )
            [1] => array2[] =>
                      (
                            [0] = element4
                            [1] = element5
                            [2] = element6
                      )
        )

I tried use array_push() or array_merge() but without success.

Thanks for hints.

What you want is called a multi-dimensional array and is explained in the PHP documentation. You create an array and then set the values of that array to be arrays as well. You can go as deep as you need, the only limit is the available RAM. To create a multidimensional array you set your key and then another array as the value, such as this example:

$finalArray = array(
    0 => array (
        0 => "element1",
        1 => "element2",
        2 => "element3"
    ),
    1 => array (
        0 => "element4",
        1 => "element5",
        2 => "element6"
    ),
);

Of course the keys are entirely optional in that example, I included them for clarity.

You can create the child arrays as separate variables first if you wish. For example:

$array1 = array (
    0 => "element1",
    1 => "element2",
    2 => "element3"
);
$array2 = array (
    0 => "element4",
    1 => "element5",
    2 => "element6"
);
$finalArray = array(
    $array1,
    $array2
);

I've done an eval.in example so you can see that they both output the same results.

Try below method.

<?php
$array1 = array("element1", element2, "element3");
$array2 = array("element4", element5, "element6");

$finalArray =  array($array1,$array2);
print_r($finalArray);
?>

Output:

Array
(
    [0] => Array
        (
            [0] => element1
            [1] => element2
            [2] => element3
        )

    [1] => Array
        (
            [0] => element4
            [1] => element5
            [2] => element6
        )

)

Try with

METHOD 1

$final = array("finalArray"=>array($array1,$array2));

OUTPUT

Array
(
    [finalArray] => Array
        (
            [0] => Array
                (
                    [0] => element1
                    [1] => element2
                    [2] => element3
                )

            [1] => Array
                (
                    [0] => element4
                    [1] => element5
                    [2] => element6
                )

        )

)

METHOD 2

$final = array_merge(array($array1),array($array2));

OUTPUT

 Array
(
    [0] => Array
        (
            [0] => element1
            [1] => element2
            [2] => element3
        )

    [1] => Array
        (
            [0] => element4
            [1] => element5
            [2] => element6
        )

)
