I think you just try to learn first PHP and then JavaScript. Every webmaster know php that it's powerful tool to creating websites so they learning it first. - its was my decision in past.
Aside from the lack of uniformity from page to page (and writing the site in PHP helps with that, since you can just include the top header and left side, from the same files, on every page), the site doesn't look bad from the user's viewpoint.
In my point >> PHP: easy to learn Javascript: easy to learn, easy to execute Now, I should choose javascript for my server side and client side scripting
You should learn both java-script and php. For dynamic site design php is essential with MySQL database and java-script is for browser based programming and to make a professional site.
One little problem - Javascript runs in the browser, not on the server. There's no way to get your Javascript code to run on the server. You have to use server-side code if you want code that runs on the server, and PHP is server-side code. IOW, if you need code running on the server and in the client, you have to use both. You have no choice.
Well both are good at their on level, If you talk about javascript it can be apply with even php,asp,etc. About Php it is a severside programming language and a open source free to use as well as understand.
PHP is use for crate dynamic websites. PHP features are best to use. Java Script is use for give the shape of website. Widely used java script today websites.
PHP is a server side language and JAVA script is a client side thing. I think you should have command in both.
