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 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.
