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. After going through the first foreach loop, array remains unchanged but, as explained above, value is left as a dangling reference to the last element in. 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. each(array) - Returns the key and the value pointed by the array internal pointer as an array and moves the pointer to the next value. In each iteration, PHP assigns the key and value of the next element to the variables (key and value) that follows the as keyword. The value of the element to the value variable. ![]() ![]() 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). There are two types of array, and the type of key that is used to access an array element dictates the array type. When PHP encounters the foreach statement, it accesses the first element and assigns: The key of the element to the key variable. The PHP arrays have elements which can be accessed via its index position, right? How to Iterate over PHP array using while loop looping over a plain old array With an array, all the results are accumulated into memory before being looped. Here is an example: Western.Keep doing it, until expression becomes false. The above is assuming the results contain the columns named id and name. If you had created the keys yourself, the key-name allows you to access every one of them. It means that, while the given expression (or condition) is true, execute the code inside the curly brackets, and check the expression again.
