What is the difference between client-side and server-side programming?

I really don't understand how Php works and i am a little nervous, i don't like the idea of using more application for a email-send system. Is there anyway to do that without php, only in javascript/html/css? Can someone explain how this works or if is there something i need to know?
I tried to find on google, but i didn't find anything useful. Thanks in advance! :)
Sending mail requires a program to run on a server, and PHP is a language that can talk to a server. You can't send an email using just HTML, CSS and Javascript.

I have another question related to that , Could I use this script as it's or I have to decode it to use at my HTML5 page ?
The point of obfuscation is to make it very challenging to restore the original code as written while maintaining the same functionality. So to answer your first question there really is no way to get back to the original code as the author clearly didn't want you to see it or be able to edit it. To answer your second question yes you should be able to use it normally assuming it was properly obfuscated.
I suggest you do a little reading on the topic: http://en.wikipedia.org/wiki/Obfuscation_%28software%29
There might be a few deobfuscation tools out there for javascript, but the chance that these work well is probably low.

I want to have two separate files in JavaScript with the same name , can i do it in javascript ?
I want to expose only part of the code to the user and not all the file
(Do we have any concept on javascript like the c# partial classes ?)
Thanks

In the Web Browser, all of the JavaScript code is interpreted locally on the user's machine. So for the Web Browser to be able to interpreted correctly it needs all of the source code. So the answer to your main question is "no".
The closest solution to your problem is doing some sort of obfuscation of the source code. When you do that, it makes the source code very hard for the user to read the source code, but the Web Browser can still interpret it.
To answer the last question, all objects in JavaScript can be extended like partial classes in C#.
Nope - you can't fully hide JavaScript from your end users. The users browser needs to be able to parse the code and as such the user will have access to it as well.
What you can try to is use some form of code obfusication. This will still allow the user's browser to parse the code but will make it very difficult for a user to read and understand what's going on.
That said, it's not impossible for a user to un-obfusicate the code and see the logic behind it - it is just another layer of security but by no means fool proof.

Is it possible to hide or scramble/obfuscate the javascript code of a webpage?
Is there any way to hide the view of JavaScript code from the view page source action?
No. You can obfuscate it a lot, though.
No. It is the same with any content on the web. If you can see or hear it, you can download it.
No.
If you have sensitive algorithms or implementations, run them on the server and access them through Ajax or at the time the page is requested. Keep the javascript on your page UI-centric.
You can hide your js code to unexpert eyes using obfuscate techniques: JS obfuscate but an expert js coder can reverse engineering and understand it

Hi there, is there any way to encrypt code written in javascript, that's displayed in the browsers window..
The below link has a similar discussion and has answer to that.
How can I encrypt JavaScript code so that it's not decryptable?
Hope this will be helpful.
You mean that you want to obfuscate your javascript code so that others cannot read it properly?
Try jCompress or any other Javascript Minifiers
There is no way to encrypt (because otherwise the browser couldn't run the code) but you can obfuscate. Just search for 'Javascript Obfuscator' .
I wouldn't recommend this though, as obfuscators can cause bugs and it is possible to deobfuscate them.
Is there any reason why you want to encrypt the javascript?
If you mean a way to encrypt it so it can't be stolen than the answer is no. The browser needs to be able to read the code to be able to execute it. There are tools to make it harder to read for humans but in the end you can't avoid people stealing your code.
Plenty of tools available on google. 1 Example: click
