foreach ($result as $value){
    echo $value;
}

With this foreach i echo only the last element of $value, it should be echo all the 12 values. Also how can i get into the array [display] and echo values ?

Answer 1

You can loop directy on the display as

foreach ($result['display'] as $display) {
    echo $display . '<br>';
}

But you can imbricate 2 loops

foreach ($result as $value) {
    if (is_array($value)) {
        foreach ($value as $display) {
            echo '----' . $display . '<br>';
        }
    } else {
        echo $value . '<br>';
    }
}

The best solution is to use a function:

function displayArray($array)
{
    foreach ($array as $each) {
        if (is_array($each)) {
            displayArray($each);
        }

        echo $each . '<br>';
    }
}

So you can call the function like this:

displayArray($result);
