Rather than going through an abstract sequence you iterate over a pre-set thing. I’ve always found PHP foreach loops much simpler to understand. If you’ve never seen this syntax before though, it’s a lot to wrap your head around. What’s great about this code is that if you’ve seen a for loop before (with its weird three-clause syntax of “start condition”, “continue condition”, “per loop operation”), this reads quite simply. You’ll probably use a for loop, like this: for ($x = 1 $x " Let’s say you want a segment of code to run 20 times. In PHP, you’ll use a for loop mostly when you want to iterate through a set of numbers. But before we get too deep on the foreach loop I do think there’s value in covering how these two popular things differ. PHP improves on the for loop with the foreach loop. Anyone who’s programmed much in any language has heard of a for loop. ![]()
