javascript, php and sql

[entrepreneur231]

can anyone let me know what the difference is?

and please go in detail

my advice would be to go on wikipedia or w3schools website. Those three would take hours and hours to tell you the difference, in detail.

If you don't know the difference between js, php, and sql, going into detail isn't going to help you much, because you won't understand it. BUT...here goes:

PHP and JS are both scripting languages, however, PHP is a server side scripting language, which means it's ONLY executed by a server (not on your computer - and if you want to test it on your computer you have to install a server - Apache). Javascript runs client side, meaning you can run it on your local computer.

SQL is a type of database that you would use PHP to modify and manipulate - there is SQL coding that is done as well, for database querying and interaction.

That's pretty much it. I also agree with the W3 Schools method of learning.

JavaScript - Browser based scripting language that is the foundation for the vast majority of web applications these days (see AJAX). JavaScript can make changes to a website at run time without page reloads and can query a database using AJAX calls to a server side scripting language like PHP.

PHP - (per php.net) PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML and can connect to a database.

MySQL - This is a database, just like SQL or MS Access.

You basically think about out all the information you will need to store and/or leverage - map it out in the MySQL database as specific tables, then build your PHP scripts to interact with your database tables and finally, use JavaScript to update your HTML content with the results of the PHP execution.

While JavaScript is not necessary to have a database driven web application, it just makes things "appear" to move faster and fluidly with virtually no additional server load.

Lastly, all 3 of these are open source technologies, which makes development and maintenance costs much lower. Hope that helps.

and all of them if combined together considered as an oop programming language and generally base on MVC pattern

M - Model
V - View
C - Controller

especially when it comes to php where in php, it is integrated in its skeleton - the xhtml. and make-up by CSS. php is basically the engine, where all the logic, process is in. in php too, an executor is in place, the C - controller who trigger the process.

javaascript is interesting. its basically a script that would bring the level of experience a bit higher in web development. - only if you know that im talking about AJAX (mootools, jquery)
