Instead of using PHP using javascript is the better option for this any way there is a function to check whether submitted data is a number or not in PHP

This can be achieved in this way
is_numeric — Finds whether a variable is a number or a numeric string
The example code is as follows
  • $num = 12;
  • is_numeric($num); //Returns true
