What is the best way to iterate through the $myarray array, assuming you want to modify the value of each element as you do?

<?php
    $myarray = array ("My String", "Another String", "Hi, Mom!");
?>

Using a for loop

Using a foreach loop

Using a while loop

Using a do...while loop

There is no way to accomplish this goal

Answer A correct

<?php
    $myarray = array ("My String", "Another String", "Hi, Mom!");
    for($i = 0; $i < count($myarray); $i++)
    {
        $myarray[$i] .= " ($i)";
    }
?>

Normally, the foreach statement is the most appropriate construct for iterating through an array. In order to be able to directly modify array elements within the loop precede value with &. In that case the value will be assigned by reference. However, because we are being asked to modify each element in the array, this option is not available, since foreach works on a copy of the array and would therefore result in added overhead. Although a while loop or a do…while loop might work, because the array is sequentially indexed. a for statement is best suited for the task.
