Subtract parallel values from two arrays

[mapg]

Hi all,

Is there a different way to do these subtract operations better than this?

I feel that this is an amateurish way ...

$diff_1 = $count_lw_comp[0] - $count_comp[0];
$diff_2 = $count_lw_comp[1] - $count_comp[1];
$diff_3 = $count_lw_comp[2] - $count_comp[2];
$diff_4 = $count_lw_comp[3] - $count_comp[3];
$diff_5 = $count_lw_comp[4] - $count_comp[4];
$diff_6 = $count_lw_comp[5] - $count_comp[5];
$diff_7 = $count_lw_comp[6] - $count_comp[6];
$diff_8 = $count_lw_comp[7] - $count_comp[7];

$diff_array = Array($diff_1, $diff_2, $diff_3, $diff_4, $diff_5, $diff_6, $diff_7, $diff_8);

Any help is welcome.

Thank you in advance.

you could loop through them and assign.

foreach($array1 AS $key => $val) {
$newArray[] = $val - $array2[$key];
}
