If we use textbox to input date of birth, data must be checked. If users enter text, special characters or a number bigger than 31, there must have a notification that the input is invalid. Commonly, we use javascript to process the data.

In order that users do not input text or special characters, you could use type=number limited from 1 to 31.

There are many systems using dropdown for the purpose of importing date. With dropdown, users do not have to enter information but choose one date in the list of dates displaying. It must be sure that data displays properly. For example, there is no 30th or 31th in February.

Using the types of input like the two above, you need to identify data and calculate properly as well. This will costs you a lot of time. There is one type that incurs less error but is more visible. It is date picker. Thanks to date picker, using date of birth in php form is not a big problem anymore.
