![]() ![]() So I have a list of numbers (in PHP, we use the array language construct to contain and identify a list), and each iteration through it we’re seeing a number, which we’re showing to ourselves via an echo command. Here’s our for loop, made into a simple foreach. 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. It starts with the first element and ends with the last one. The foreach statement iterates over all elements in an array, one at a time. We shall go through the following scenarios, with programs. PHP provides you with the foreach statement that allows you to iterate over elements of an array, either an indexed array or an associative array. 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. In PHP, foreach is a construct that allows to iterate over arrays easily. ![]() In each case, the basic form of the alternate syntax is to change the opening brace to a colon (:) and the closing brace to endif, endwhile, endfor, endforeach, or endswitch, respectively. You’ll probably use a for loop, like this: for ($x = 1 $x " PHP offers an alternative syntax for some of its control structures namely, if, while, for, foreach, and switch. Let’s say you want a segment of code to run 20 times. In this tutorial, we will explore in-depth of PHP foreach loop. We will first look at how the foreach() function works on an indexed array. We will learn in turn how the PHP foreach function works on both these types of arrays. In PHP, you’ll use a for loop mostly when you want to iterate through a set of numbers. Foreach is one of the advance loop feature provided by PHP. As we learned in the Syntax of PHP foreach() section above, the foreach function can work on both indexed and associative arrays. 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. PHP then iterates over this new copy of the array rather than the original one. In foreach loop, the first thing php does is that it creates a copy of the array which is to be iterated over. Anyone who’s programmed much in any language has heard of a for loop. PHP foreach loop can be used with Indexed arrays, Associative arrays and Object public variables. ![]()
