Question

I created two arrays. First the arrays show the elements with no order whatsoever. So, I have to sort them first by alphabetical order and lowest-to-highest. Once in order, the two arrays that need to be combined in such way that each element from each array are combined according to their index number.

My goal: a0 b1 c2 d3 e4 f5 g6

What I’m getting: abcdefg0123456

$array1 = array("b", "f", "g", "a", "c", "d", "e");
    $array2 = array("5", "0", "1", "4", "3", "2", "6");
    sort($array1);
    sort($array2);

    echo "<pre> \n";
    print_r($array1);
    echo "</pre> \n";

    echo "<pre> \n";
    print_r($array2);
    echo "</pre> \n";

    echo "<h3 style='font-family:Helvetica'>Combining Arrays</h3>";
    $array3 = array_merge($array1, $array2);


    for($i = 0; $i < 7; $i++)
    {
        for($j = 0; $j < 7; $j++)
        {
            echo $array3[$i] [$j];
        }
    }

This can not be done by array_merge. Use simple loop.

   

    $array1 = array("b", "f", "g", "a", "c", "d", "e");
    $array2 = array("5", "0", "1", "4", "3", "2", "6");
    sort($array1);
    sort($array2);
    for($j = 0; $j < 7; $j++){
        echo "{$array1[$j]}{$array2[$j]} ";
    }
