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. 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. You can simply use the foreach loop in combination with the for loop to access and retrieve all the keys, elements or values inside a multidimensional array.

We shall go through the following scenarios, with programs. 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). In PHP, foreach is a construct that allows to iterate over arrays easily. Inside foreach block, we will print square of the element.

The PHP arrays have elements which can be accessed via its index position, right? foreach with Array In this example, we will take an indexed array of elements, iterate over each of the elements in the array, and execute a block of code (or statements) for each element.
