基于其他数组替换数组中的值

Question

I would like to replace the value of a multidimensional array if a corrosponding array contains a certain value.

Basically, I have two multidimensional arrays. One contains the actual data and the other contains a yes/no for whether the first array should be modified.

Is there any way to do this:

if optB[i][i] contains 'yes'
        then opt[i][i] = '<strong>'.opt[i][i].'</strong>';

I'm lost as to whether this is even possible. Any help would be greatly appreciated -- thank you!

Thank you for the help so far. Here is the array:

[opt] => Array
    (
        [0] => Array
            (
                [0] => value1
                [1] => value2
            )

        [1] => Array
            (
                [0] => value3
                [1] => value4
            )

    )

[optB] => Array
    (
        [0] => Array
            (
                [0] => on
            )

        [1] => Array
            (
                [1] => on
            )

    )

Those are some interesting arrays because usually numeric arrays always have a 0. I imagine you may have some different key combination so I think this is the best "future-proof" method:

foreach ($optB as $i => $optB2) {
    foreach ($optB2 as $j => $val) {
        if ($val) {
            $opt[$i][$j] = '<strong>' . $opt[$i][$j] . '</strong>';
        }     
    }        
}
