What is PHP
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.
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.
-PHP is open source and free.
-Short learning curve compared to other languages such as JSP, ASP etc.
-Large community document
-Most web hosting servers support PHP by default unlike other languages such as ASP that need IIS. This makes PHP a cost effective choice.
-PHP is regular updated to keep abreast with the latest technology trends.
-Other benefit that you get with PHP is that it’s a server side scripting language; this means you only need to install it on the server and client computers requesting for resources from the server do not need to have PHP installed; only a web browser would be enough.
-PHP has in built support for working hand in hand with MySQL; this doesn’t mean you can’t use PHP with other database management systems. You can still use PHP with
+Postgres
+ Oracle
+MS SQL Server
+ODBC etc
-PHP is cross platform; this means you can deploy your application on a number of different operating systems such as windows, Linux, Mac OS etc.
