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.
Generally client side validation uses functions or a validation object and methods to check that a user has entered valid data, and that all required data is entered. Validation for text fields is often done by attaching a function call to the "blur" event of the text element. Validating that all required data is present is normally done by attaching an event to the "submit" event on the form. In all cases, you have to be aware that client side validation is only useful for user experience. It cannot be relied on, and so even with it, server side validation has to be done on the submitted data. This is true even in cases where AJAX is employed, as all client side code is suspect.

Validation allows you to limit what goes into cells. By applying validation you can do things like put an lower and upper limit on numbers entered into a cell, like allow only values between 1 to 100. You can also use it to highlight cells that already have values that are not valid, by applying validation and getting Excel to draw red ovals around the ones that are invalid. This can help you find errors in values that have already been entered. Validation allows you prompt the user to tell them what can be entered and also give them a message to tell them what they have done wrong.
It is important to be as accurate as possible in entering the data. Anything that can be done to help that is beneficial. So being able to validate what is entered is important. The amount of errors made can be reduced. So validation is supplied in spreadsheets to assist that process.
