PHP Tutorial - Databases in PHP, SQL Basics. In the last part of this tutorial series we talked about the basic structure of databases in modern database management systems (DBMS) and mentioned the structured language used in accessing those databases. The language is the Structured Query Language, SQL, which is commonly pronounced as if it was a word - "Seekul". Now, before we get into coding specific commands in PHP, it is very worthwhile to get an overview of the basic elements of the language and the purpose of those elements. In SQL everything is done in a "query". Personally I think this must be because somebody got the idea that since it's a query language, everything must be a query, and made it so even if it's an instruction like "add this record".

Each time you check (using the "which" method) the counter increments so that the next time you check the state will have changed. This is the perfect class for using when you're outputting an HTML table and want to use different classes to differentiate between odd and even rows.
Simply create a new instance and call OddEven->which() for each row! Manuel PHP.
