    • <?php//What is PHP??>
      Presentation by Helen Pitlick
    • PHP (Hypertext Preprocessor) is....
      • "PHP is a server-side, HTML-embedded, cross-platform scripting language—quite a mouthful"
      • free and open-source
      • a way to produce dynamic web pages (sites that are unique to the user or continuously updated).
      • clear and easy to read and de-bug, as well as flexible, scalable, and extensible.
      • used by 20 million websites and 1/3 of the web's servers 
      • installed as an Apache module on Unix (Macs or Linux), or as a CGI script on Unix or Windows
    • The father of PHP:
      Rasmus Lerdorf
      invented PHP as his personal homepage in 1994 (version 1.0).
      2010 = version 5.3.2

    • PHP scripts are plain-text files with PHP instructions; the language borrows from C and Perl, and can be imbedded into HTML. The pages are treated similarly to HTML pages.
      How it works: you write code, the server reads it, and then replaces it with content in the browser.

    • PHP is good for....
      • supporting 3rd party databases, like MySQL or Microsoft's SQL.
      • allowing developers to include files, like GIFs, PNGs, and JPEGs
      • companies with lower budgets, since there are no licensing fees or hardware involved.
    • Uses for PHP
      • Feedback forms• e-commerce systems• User registration, log-ins, and online dashboards• Guest books• Discussion forums and message boards
    • Why is PHP important?
      • it's fast (compared to ASP or Java) 
      • it's flexible (compared to Perl or C)
      • it's open source: a money saver
