PHP Operators

What can you do without operators? Not much, if you're trying to do without them in a programming language, and PHP is no exception. On Monday, we barely had time to show you a long list of the operators in PHP. Today, we're going to show you what they do.

In our last tutorial I left you with a giant table full of operators to study. But I know you, and you are a slacker, so instead of making you go back to that previous article like I should, I am going to spot you one and post it here for you again. That and well...it helps increase my word count. All hail laziness!

So there you go. No, you aren't having deja vu. That's just a glitch in the Matrix. Like the third part in that movie series. I mean, way to ruin a trilogy. Let's create a third movie and then have the main characters, who have been the focus of the previous two movies, only be in the final installment for like 20 minutes. Don't get me started.

Okay where was I?
