Therefore, with each iteration, variable will move to next index position. Since, while loop will not increment our index variable automatically, we need to increment it inside the loop. Simpler more efficient code once you have keys: foreach (keys as key). The array is then copied using a foreach loop to make a duplicate array where the key and value order correspond to the first array, but the keys are sequential. 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). The loop will start from the first element of the array and work through all the elements in order until it reaches the end. The key difference between the two is that foreach automatically starts at the front of the array, whereas list()/each() does not. Here, we will create an index position variable and start with 0th position which is first in an array. I was expecting this code to add the key-value pair a > a as a sibling to d > 1 of each item in the list. A foreach loop in PHP is perfect for looping through elements part of an indexed array or an associative 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? You can access the key-value pairs present in an associative array using the following foreach syntax: It traverses the iterable pointed by array, and on each. How to Iterate over PHP array using while loop 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.
