PHP

Is not fair to compare PHP vs JavaScript, as they both have different purposes for web-site development. PHP is a server-side scripting language while JavaScript is a client-side scripting language. In fact, the most dynamic website is created when we use functions of both these languages together. If PHP is like a paint-brush to paint picture, then JavaScript is a paint-color.

PHP stands for "Hypertext Preprocessor", is a programming language embedded in HTML that does all sort of things like build custom web content, send and receive cookies, evaluate form data sent from a browser, etc. It is integrated with number of popular databases like Postgre SQL, Oracle, Sybase, SQL, and MySQL. PHP also supports major protocols like IMAP, POP3 and LDAP.

PHP can handle forms, save data to a file, return data to the user, gather data from files, etc.

Example: Let say a website that takes user to view the order status after logging in. By PHP coding, you would send a query to the database that would then output the specific user information based on what information is in the database

JavaScript

While, JavaScript is designed for creating network-centric applications. With JavaScript, web pages will no longer be static HTML and allows the program that interacts with the user, control the browser, and dynamically create the HTML content. The advantage of JavaScript is that it has less server interaction, allowing you to validate user input before sending the page off which means less load on your server and less server traffic. JavaScript allows immediate feedback to the visitors.

Example: When you hover over the menu tab on the web-page, the drop down effect is done through JavaScript.

Note: JavaScript now supports server side execution via NodeJS

Likewise, regional interest of people for these two languages are also highlighted over-here. In graph, though we can see the fall of interest of PHP and JavaScript languages over the period of time due to introduction of new languages, JavaScript still remains on top of PHP.
