You’ve got more there than you need and your additional ifs are complicating it.
if ($row_count) {
$size = (int)12/$row_count;
}
This calculates the width of the row
if there is 1 row the result is 12 (col-12)
if there is 2 rows the result is 6 (col-6)
3 result 4 (col-4)
4 result 3 (col-3)
5 result 2 (actually 2.4 rounded to int) (col-2)
6 result 2 (col-2)
The only thing I did here was to add
if ($size < 2) {
//force minimum of col-lg-2
$size = 2;
}
assuming you did not want to have a column smaller than that.
