Well completely different. If what you see in terms of code looks the same, the place where both languages express their ability is not the same. Yet they are complementary.

While Php runs on your server and has the main function to produce html code for your browser to read, Javascript runs on your browser and execute specific local tasks.

Good explanation, though I might add that javascript can do things locally in real time, like clock countdowns, that PHP simply can not do for the reason you stated. For example, php needs to do a page refresh to increment a counter, javascript does not. Php is a lot more friendly in terms of doing database manipulation and server side scripting/processing that javascript would be impractical to use, generally.

PHP is open source best web programming language.PHP used mostly website developing. But java script is a validation of form and form details programming language.

PHP is a server side programming language, which is ran into the web server when a page is generated, before being sent to the browser.

Javascript is a client side scripting language, that run into the browser, and is allowed to interact with the element that are present into the page.

PHP run only during the page load. Once the page is loaded, no more PHP can be run.
Javascript starts only when the page is received. For more information check out web application development

JavaScript is a browser based function script, and PHP is a server side function script.

I'm still learning PHP, but I'm very well versed in javascript. Arguments concerning accessibility and support aside, the primary differences between the two are -

a.) Syntaxing and some of the object and array handling
b.)PHP -cannot- be run client side

Javscript is almost exclusively used on the client side because of the lack of support for JS services from hosting companies. JS -can- be run on either side of the line, which makes it significantly more flexible than PHP, not to mention the growing popularity and support of JSON (JavaScript Object Notation) syntaxing.

Here is the difference between both:

What is PHP?

* PHP stands for PHP: Hypertext Preprocessor
* PHP is a server-side scripting language, like ASP
* PHP scripts are executed on the server
* PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.)
* PHP is an open source software
* PHP is free to download and use

What is JavaScript?

* JavaScript was designed to add interactivity to HTML pages
* JavaScript is a scripting language
* A scripting language is a lightweight programming language
* JavaScript is usually embedded directly into HTML pages
* JavaScript is an interpreted language (means that scripts execute without preliminary compilation)
* Everyone can use JavaScript without purchasing a license

yes both are different in their behavior as php is complete language with pretty dynamic behavior with too much functionality based on server but java script mostly used for only local functions and it is used for validation only.
