Change your line: $int_var1 = ($counter/3); //current counter will be divided by 3 $int_var2 = ($counter/5); //current counter will be divided by 5 with $int_var1 = ($counter % 3); //current counter will be divided by 3 $int_var2 = ($counter % 5); //current counter will be divided by 5 and rather checking for gettype(), you can check for the remainder, which will be returned in your variables $int_var1 and $int_var2. If remainder is 0 (zero) then it's your required number otherwise remainder will be greater than 0. Modulus is an arithmetic operator and much faster than type casting like you are doing with gettype() and checking on the string "integer". FYI: Type casting means converting data from one data type to another. i.e: converting a digit into string or into boolean, this is called type casting, and it always has payload. Dear Asim,

$int_var1 = ($counter/3); //current counter will be divided by 3
$int_var2 = ($counter/5); //current counter will be divided by 5

with

$int_var1 = ($counter % 3); //current counter will be divided by 3
$int_var2 = ($counter % 5); //current counter will be divided by 5

and rather checking for gettype(), you can check for the remainder, which will be returned in your variables $int_var1 and $int_var2. If remainder is 0 (zero) then it’s your required number otherwise remainder will be greater than 0.
