Question

Can’t seem to find anything on this, though I might just not know what i’m looking for.

I want to check if out of 6 variables, how many of them are yes. So if four return “no” values, then two are yes.

I was thinking to set up an if chain where

$var_array = 0;
if ($var1 == "yes"){
  $var_array++;
}
if ($var2 == "yes"){
  $var_array++;
}

Then use the array to tell me how many yes values were returned.
Which naturally would work, but would be a long process. Is there an easier way [or more eloquent] to do this?

Answer 1

$vars = array($var1, $var2, $var3, $var4, $var5, $var6);
$yes_count = 0;
foreach($vars as $var) {
  if($var == "yes")
    $yes_count++;
}
