Variables are nothing but identifiers to the memory location to store data. We can create any number of varibles. In PHP all the variables begin with a dollar sign "$" and the value can be assignes using the "=" operator as shown below: Another important thing in PHP is that all the statements must end with a semicolon ";". In PHP we needn't have to specify the variable type, as it takes the data type of the assigned value. From the above example we understand that '$Name' is of Data type String and '$Age' is of type Numeric.

PHP has become a more popular technology for web programming in the recent years due to its open source technology. This means that it is free to use and is compatible with almost any server, say Windows, Linux/Unix and Apache servers. Though it is an open source technology, it has many advanced features included in it and is now capable of handling almost any issue related to the internet. PHP stands for "PHP Hypertext Preprocessor". PHP is a server-side scripting language. This means that a PHP page is processed on a Web server by a PHP script engine. When the client makes a request for any page, the request is sent to the server, the server locates the requested page and executes the PHP code if any and the result is sent to the browser (client) in the form of HTML. The browser then compiles the HTML to display the output.

PHP is a freely available, HTML-embedded scripting language that lets you embed special tags to create your script right in an HTML file. PHP can be integrated into the Web server itself, eliminating the need to start up a separate CGI program to generate the Web page, which can lead to dramatic performance increases on some systems. This article describes how PHP came into existence, introduces some PHP basics, then shares some useful, instructive scripts to get you started.

Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by the string separator. If limit is set, the returned array will contain a maximum of limit elements with the last element containing the rest of string.

Arrays can be used in many ways to store and organize data quickly and efficiently. It is one of the more useful data types available to any programming language. This article describes the basics to create and make operations with indexed, associative, and multidimensional arrays.

Array does not have to be a simple list of keys and values; each array element can contain another array as a value, which in turn can hold other arrays as well. This way, you can create a multi-dimensional array. In this article principles of using multidimensional arrays are explained and source code defining multidimensional array and displaying the array values on the web page is given.

A function is a block of code which can be called from any point in a script after it has been declared. It is basically a compartmentalized PHP script designed to accomplish a single task. Functions are useful because they contribute to rapid, reliable, error-reducing coding, and increase legibility by tiding up complicated code sequences.
