Chapter 1: What is PHP?Write your first PHP ProgramWhat is PHP?PHP is a server side scripting language. that is used to develop Static websitesor Dynamic websites or Web applications. PHP stands for Hypertext Preprocessor, 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".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. Scriptsare usually embedded into other software environments.The purpose of the scripts is usually to enhance the performance or performroutine tasks for an application.Server side scripts are interpreted on the server while client side scriptsare interpreted by the client application.

PHP is a server side script that is interpreted on the server while JavaScriptis an example of a client side script that is interpreted by the clientbrowser. Both PHP and JavaScript can be embedded into HTML pages.Programming Language Vs ScriptingLanguageProgramming languageHas all the features needed to develop completeapplications.The code has to be compiled before it can beexecutedDoes not need to be embedded into otherlanguagesScripting languageMostly used for routine tasksThe code is usually executed without compilingIs usually embedded into other softwareenvironments.What does PHP stand for?PHP means - Personal Home Page, but it now stands for the recursivebackronym PHP: Hypertext Preprocessor.PHP code may be embedded into HTML code, or it can be used incombination with various web template systems, web content managementsystem and web frameworks.Php SyntaxA PHP file can also contain tags such as HTML and client side scripts

such as JavaScript.HTML is an added advantage when learning PHP Language. You caneven learn PHP without knowing HTML but it’s recommended you atleast know the basics of HTML.Database management systems DBMS for database poweredapplications.For more advanced topics such as interactive applications and webservices, you will need JavaScript and XML.The flowchart diagram shown below illustrates the basic architecture of aPHP web application and how the server handles the requests.

Why use PHP?You have obviously head of a number of programming languages out there;you may be wondering why we would want to use PHP as our poison for theweb programming. Below are some of the compelling reasons.PHP is open source and free.Short learning curve compared to other languages such as JSP, ASPetc.Large community documentMost web hosting servers support PHP by default unlike other languagessuch as ASP that need IIS. This makes PHP a cost effective choice.PHP is regular updated to keep abreast with the latest technologytrends.Other benefit that you get with PHP is that it’s a server side scriptinglanguage; this means you only need to install it on the server and clientcomputers requesting for resources from the server do not need tohave PHP installed; only a web browser would be enough.PHP has in built support for working hand in hand with MySQL; thisdoesn’t mean you can’t use PHP with other database managementsystems. You can still use PHP withPostgresOracleMS SQL ServerODBC etc.PHP is cross platform; this means you can deploy your application on anumber of different operating systems such as windows, Linux, Mac OSetc.

What is PHP used for & Market shareIn terms of market share, there are over 20 million websites and applicationon 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 PHPPHP vs Asp.Net VS JSP VS CFMLASP – Active Server Pages, JSP – Java Server Pages, CFML – Cold FusionMarkup language The table below compares the various server side scriptinglanguages with PHP
