Question

I have a function (for ease, I’ll just use count()) that I want to apply to maybe 4-5 different variables. Right now, I am doing this:

$a = count($a); $b = count($b); $c = count($c); $d = count($d); 

Is there a better way? I know arrays can use the array_map function, but I want the values to remain as separate values, instead of values inside of an array.

Thanks.

I know you said you don’t want the values to be in an array, but how about just creating an array specifically for looping through the values? i.e.:

$arr = Array($a, $b, $c, $d);  foreach ($arr as &$var) {    $var = count($var); } 

I’m not sure if that really is much tidier than the original way, though.
