![]() At the same time, it’s arguably more readable, but ultimately, it all comes down to preference. It’s essentially a longer or code-bulkier way of executing a while loop, which in a way, is pretty pointless. You could almost say the do while loop is pretty scarce among PHP code, I personally rarely use it and similarly rarely see it from other peoples code neither. And, if you name your variables well, the code will make a lot more sense than other looping methods. PHP Code $foodArray = Īs you can see within the code example, there is much less fluff in terms of code. There isn’t a mandatory rule to use a numeric index to pick out data values, the foreach loop essentially rids this concept for you. It’s both easy to use, understand and comes in handy for many use-cases. This type of loop is my personal favorite way to read arrays, there is no need for a boolean test, just simply pass in the array and do what you want with it. Three parameters are needed for the for loop and they are as follows – It uses the very same concept for looping and picking out information from the array. $arrayLength = count($CodeWallTutorialArray) Īs demonstrated in the last section for while loops, you will see how similar the for loop is. It’s somewhat very similar to how a for loop works, which we will touch on later. To achieve this, another variable must be created, an index indicator variable that does two things, allows us to pick out each of the values in the array as well as instructing the while loop when to stop. With a plain array, we can create a true or false value depending on if the array has been looped over till the end. This method is commonly used when working with database results in the style of arrays but at the same time, are a completely feasible way to read non-database result-arrays. Whilst something is true, the loop will continue looping or vice versa. I always like to think of the while loop as the following. The while loop is probably the most popular because of the recognizable and meaningful name. In this article, I will walk-through each possibility for reading arrays whilst looping. ![]() The most popular ways to do it usually is with a while, for and foreach operator, but, believe it or not, there are more ways to do it with PHP. PHP, just like most other programming languages has multiple ways to loop through arrays.
