Merging 3 arrays in PHP

Question

I have 3 arrays as below.

$array1 = Array
(
    [0] => 05/01
    [1] => 05/02
)

$array2 =Array
(
    [0] => ED
    [1] => P
)

$array3 =Array
(
    [0] => Mon
    [1] => Tue

)

I want to merge these 3 arrays as below $result_array. I have written a code as below. But It gave a empty array.

$result_array =Array
(
    [0] => Array
        (
            [0] => 05/01
            [1] => ED
            [2] => Mon
        )
    [1] => Array
        (
            [0] => 05/02
            [1] => P
            [2] => Tue
        )
)

Code:

for($z=0; $z<count($array1); $z++){
    $all_array[$z][] = array_merge($array1[$z],$array2[$z] );
    $all_array2[$z] = array_merge($all_array[$z],$array3[$z] );
}

Please help me to do this.

Answer 1

this work for n of arrays and dynamic length of array

function mergeArrays(...$arrays)
{

    $length = count($arrays[0]);
    $result = [];
    for ($i=0;$i<$length;$i++)
    {
        $temp = [];
        foreach ($arrays as $array)
            $temp[] = $array[$i];

        $result[] = $temp;
    }

    return $result;

}

$x = mergeArrays(['05/01' , '05/02'] , ['ED' , 'P'] , ['Mon' , 'Tus']);
$y = mergeArrays(['05/01' , '05/02' , 'X'] , ['ED' , 'P' , 'Y'] , ['Mon' , 'Tus' , 'Z'] , ['A' , 'B' , 'C']);

var_dump($x);
var_dump($y);
