php - How to use mysqli_real_escape_string for int value? -


i have $search= mysqli_real_escape_string($conn,$_post['search']); now, want know if can converted int , safe option avoid sql injection.

$sql ="select * basket quantity =$search";

**here quantity int

yes, strictly speaking, casting variable (int) or intval() removes risk of variable causing sql injection.

but not reason avoid using query parameters.

for 1 thing, might have both string , integer variables combine sql statement. makes code more complex use different methods of making variables safe, depending on type. if use query parameters variables, simplify code.

please right.
