![]() ![]() Therefore, with each iteration, variable will move to next index position. Im not sure how to go about making it recursive, but I didnt need that. That being said, I looked for a method of normalizing the array and couldnt find one, so I built my own. The ‘foreach’ loop implicitly does this too. In addition to this, no condition needs to be set that would be needed to exit out of the loop. The ‘foreach’ loop works with arrays only, with the advantage that a loop counter wouldn’t need to be initialized. I wound up with off ball arrays I couldnt access. The ‘foreach’ loop in PHP helps in accessing key value pairs within an array. Since, while loop will not increment our index variable automatically, we need to increment it inside the loop. There are two types of array, and the type of key that is used to access an array element dictates the array type. arraykeys (PHP 4, PHP 5, PHP 7, PHP 8) arraykeys Return all the keys or a subset of the keys of an array. The condition will be to continue fetching element from an array til our index values is less than the count of array (or length of the given array). Here, we will create an index position variable and start with 0th position which is first in an array. So, we can use the while loop to change the index position incrementally or decrementally therefore accessing every element (or selective elements as per the condition). ![]() The PHP arrays have elements which can be accessed via its index position, right? For that, we have created an associative array of three. ![]() How to Iterate over PHP array using while loop When PHP encounters the foreach statement, it accesses the first element and assigns: The key of the element to the key variable. In this example, we will use the other way of using the foreach loop i.e. Keep doing it, until expression becomes false. It means that, while the given expression (or condition) is true, execute the code inside the curly brackets, and check the expression again. ![]()
