Question

I have two array and two check boxes. The array values are

  $a={1,2,3,4,5} --->It' for first Check box
  $b={5,6,7,8,9} --->It' for Second Check box

When I check the first check box only I want the result is

 $c[0]=1,$c[1]=2,$c[2]=3,$c[3]=4,$c[4]=5

And I check the second check box only I want the result is

$c[0]=5,$c[1]=6,$c[2]=7,$c[3]=8,$c[4]=9

And I have check both check boxes I want the result is

$c[0]={1+5},$c[1]={2+6},$c[2]={3+7},$c[3]={4+8},$c[4]={5+9}

It's Possible?

Answer 1

You can achieve this using a for() loop. Please note that this code assumes both arrays are the same size:

$c = array();
for($i = 0; $i < count($a); $i++)
{ 
    $c[] = ($a[$i] + $b[$i]);
}

print_r($c);
