I have two arrays:

$my_array1= array("A", "B");
$my_array2= array("1", "2");

Is it possible to use variables ($x) in the index of the array like this:

for ($x = 1; $x <= 2; $x++) {
Echo $my_array.$x[0];
}

How to achieve this?

After referred in comment , i think it's work : here

$my_array1= array("A", "B");
$my_array2= array("1", "2");

and re-use your loop like:

    for ($x = 1; $x <= 2; $x++) {
    // to init the new name of array
    $init = 'my_array'.$x;
    // to use variable in the name of variable 
    Echo $$init[0];
    }

I hope it's help you
