PHP

Otherwise known as PHP: Hypertext Preprocessor, is by far one of the most useful languages out there. There's practically no limit to the number of things it can do. For instance, using this blog deals with PHP. You would enter information like a blog title, and description and once you hit submit, the information is all stored in a database. The database is basically a giant table where you got different columns for things like "post number", "post title", "date of posting", "labels", etc. You could even create your own blog, quite simply from scratch. You would have to do this is you get the teacher Amir Khawaja for a GRC276 class.

The most important thing to learn, besides the codes to use, is how to use it. If you know how it will gather the information and display it, the job is half done. For the blog example, you would have these steps to understand:

1. Knowing how the information input gets stored in the database
2. Knowing how to read / access the information in the database
3. Knowing how to display the information that has been read / accessed

If you understand how something will do it's job, finding the code in a book, or online can easily be done. Then if you encounter an error, you know how it should work and can (sometimes) simply solve it.
