The purpose of form validation is to ensure that valid data is input provided by the user of the web page.
If the data provided in the form is incorrect and used without proper validation we may end up using inconsistent data that would be of no use to us.
Let me explain with an example. Let us say you are designing a page where the user enters his details to register to use your site, you need to ensure that he enters a valid email address, telephone number etc. Let us say he enters xxyydsdf in the email text field and abcdedf in the phone number field, your form should be in a position to find it out and tell the user that the data he entered is wrong. Also our code should stop him submitting the information.
Else, on some day when the user has used the website for some malicious purpose and you need his contact information which the law enforcement authorities request, if you provide xxyydsdf as email and abcdedf as phone number it would be the worst thing that can happen to you.

What is type check validation?
A type check validation validates whether or not the data you typed in a field on a web form is actually of the type of field it is. For example, this check won't let you type in "four thousand" in a number box, but will let you type in 4,000. It will also stop you from entering incorrect dates, like 13/13/11 or 31/02/97 (there aren't 31 days in February!)
How does form validation differ in JavaScript and PHP?
In JavaScript the validation is done client side, which means it can be easily bypassed by turning JavaScript off in your browser. But with PHP it is server side, which means you can't switch it off, so you can't bypass the validation.
