PHP

Learning PHP is usually the first step in web programming. It is the largest and the most popular web programming language. It’s been around since the 90's and has powered the majority of popular websites including Digg, Facebook, Yahoo and every WordPress blog. Among all the server-side language or programming language used in developing a website and web application; PHP and MySQL are the preferred choice and used by most people around the world.

PHP is a widespread HTML – also an embedded scripting language which is broadly used to create dynamic web pages rapidly and effortlessly. Full form of PHP is Hypertext Preprocessor, earlier it was known as Personal Home Page. It is open source software invented by Rasmus Lerdorf in the year 1995. It's usage can also be as general purpose programming language.

AJAX, stands for Asynchronous JavaScript and XML. It's just a way to have the client requested data from the server without having to reload the entire page.

jQuery has a number of built-in AJAX functions and $.ajax() or jQuery.ajax() is one of them.

Most of the time, we'll use one or two of them, but there is one method that rules them all. It's the generic version of the call and it's simply called $.ajax().

$.ajax() is quite powerful ajax function because it enables us to pass parameters too to the PHP file to get the filtered result.

For Example:
HTML Code:
Copy the following code and paste in your .html file.

<button id="homeBtn">HOME</button>
<button id="aboutBtn">ABOUT US</button>
<button id="coursesBtn">COURSES</button>
<span id='loadc'></span>

Paste the following JavaScript link in the head of your .html file.

Are you looking to make a career in PHP or want to learn fundamentals or in-depth of PHP, then you have landed at right place. In my counseling career I have came various clients who want to learn PHP but are confused as to where from start. So through this write up, I would like to clarify this question. Here I have tried to render the eligibility criteria depending upon varied requirements of PHP.

First of all I would like to clarify what is PHP. PHP is the popular open source server-side scripting language widely used for producing web pages. If we put it simply,” PHP language is for controlling the backend administration of a website.” In-fact various open source applications like Drupal, Joomla, WordPress, Os Commerce, Magento and so on are developed in PHP MySQL itself.

I am sure you have learnt about PHP Filters in your PHP course. PHP filters are very useful in dealing with data security and data management. Data security and data management is a major concern in all PHP applications. Data management refers to the handling of data and maintaining it for use and processing of the application in PHP. Data for an application in PHP programs can have two sources, one could be the internal organization which runs the application and the other could be the external data. The data from the internal organization is easy to handle as it is pre-organized in the required formats. The main challenge faced while working with the external data. The external data could include the data from the user input, cookies, web services, server variables and database query results.
