PHPBuilder.com has posted the eighth part of their introductory "ABCs of PHP" series today. This time the focus is on looping and decision functionality (like if/while/for/etc).
n any given computer language (PHP is no exception) there has to be a way to allow the running code to decide between doing 2 different things. If there wasn't then software would not be able to adapt based on operating conditions, or it wouldn't be able to decide between two different users.
They look at using: if statements and operators, for loops and while loops. When they look at the operators, they talk about the differences between equals/not equals, grater than/less than and two of the boolean operators - AND and OR.
