Nice, but what does that mean? An example: Example #1 An introductory example
Instead of lots of commands to output HTML (as seen in C
or Perl), PHP pages contain HTML with embedded code that does "something" (in this case, output "Hi, I'm a PHP script!"). The PHP code is enclosed in special start and end processing instructions What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server, generating HTML which is then sent to the client. The client would receive the results of running that script, but would not know what the underlying code was. You can even configure your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve. The best part about using PHP is that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Don't be afraid to read the long list of PHP's features. You can jump in, in a short time, and start writing simple scripts in a few hours. Although PHP's development is focused on server-side scripting, you can do much more with it. Read on, and see more in the What can PHP do? section, or go right to the introductory tutorial if you are only interested in web programming. There are no user contributed notes for this page. PHP is a server side scripting language. that is used to develop Static websites or Dynamic websites or Web applications. PHP stands for Hypertext Pre-processor, that earlier stood for Personal Home Pages. PHP scripts can only be interpreted on a server that has PHP installed. The client computers accessing the PHP scripts require a web browser only. A PHP file contains PHP tags and ends with the extension “.php”. In this tutorial, you will learn-
What is a Scripting Language?A script is a set of programming instructions that is interpreted at runtime. A scripting language is a language that interprets scripts at runtime. Scripts are usually embedded into other software environments. The purpose of the scripts is usually to enhance the performance or perform routine tasks for an application. Server side scripts are interpreted on the server while client side scripts are interpreted by the client application. PHP is a server side script that is interpreted on the server while JavaScript is an example of a client side script that is interpreted by the client browser. Both PHP and JavaScript can be embedded into HTML pages. Programming Language Vs Scripting Language
What does PHP stand for?PHP means – Personal Home Page, but it now stands for the recursive backronym PHP: Hypertext Preprocessor. PHP code may be embedded into HTML code, or it can be used in combination with various web template systems, web content management system and web frameworks. PHP Syntax
A PHP file can also contain tags such as HTML and client side scripts such as JavaScript.
The flowchart diagram shown below illustrates the basic architecture of a PHP web application and how the server handles the requests.  Why use PHP?You have obviously heard of a number of programming languages out there; you may be wondering why we would want to use PHP as our poison for the web programming. Below are some of the compelling reasons.
What is PHP used for & Market shareIn terms of market share, there are over 20 million websites and application on the internet developed using PHP scripting language. This may be attributed to the points raised above; The diagram below shows some of the popular sites that use PHP
PHP vs Asp.Net VS JSP VS CFMLASP – Active Server Pages, JSP – Java Server Pages, CFML – Cold Fusion Markup language The table below compares the various server side scripting languages with PHP
PHP File ExtensionsFile extension and Tags In order for the server to identify our PHP files and scripts, we must save the file with the “.php” extension. Older PHP file extensions include
PHP was designed to work with HTML, and as such, it can be embedded into the HTML code. You can create PHP files without any html tags and that is called Pure PHP file . The server interprets the PHP code and outputs the results as HTML code to the web browsers. In order for the server to identify the PHP code from the HTML code, we must always enclose the PHP code in PHP tags. A PHP tag starts with the less than symbol followed by the question mark and then the words “php”. PHP is a case sensitive language, “VAR” is not the same as “var”. The PHP tags themselves are not case-sensitive, but it is strongly recommended that we use lower case letter. The code below illustrates the above point. We will be referring to the PHP lines of code as statements. PHP statements end with a semi colon (;). If you only have one statement, you can omit the semi colon. If you have more than one statement, then you must end each line with a semi colon. For the sake of consistency, it is recommended that you always end your statement(s) with a semi colon. PHP scripts are executed on the server. The output is returned in form of HTML. PHP Hello worldThe program shown below is a basic PHP application that outputs the words “Hello World!” When viewed in a web browser. Output: Hello world Summary
Why is PHP a scripting language?PHP is Scripting language because we can embed php code into HTML. If code of programming language can emmbed with other language or integrate with other language or script called scipting language. PHP is server side language because php requires server to run a code.
Is PHP a server language?PHP is a server-side scripting language designed to be used for web purposes. Originally PHP was short for “Personal Home Page” but over time it evolved to include that in its recursive current expansion “PHP: Hypertext Preprocessor”.
What is PHP language example?Typically, it is used in the first form to generate web page content dynamically. For example, if you have a blog website, you might write some PHP scripts to retrieve your blog posts from a database and display them. Other uses for PHP scripts include: Processing and saving user input from form data.
Is PHP a common language?PHP is known to be the most frequently used programming language. According to W3Techs, 78.8% of all websites are using PHP for their server-side.
