You have been given a code snippet as follows:

$somearray = array("hi", "this is a string", "this is a code");

You want to iterate this array and modify the value of each of its elements. Which of the following is the best possible to accomplish the task?

Do while loop

Foreach loop

For loop

While loop

Explanation: Generally, the for each loop is the most appropriate construct to iterate an array. As of PHP 5, it is possible to customize objects iteration too. Hence, the for each loop will be the most appropriate answer for this question.

Answer option C is incorrect. Since the array is sequentially indexed, the for loop will be the good choice to accomplish the task. However, it is not better than for each loop. For example:

<?php
 $somearray = array("hi", "this is a string", "this is a code"); 
 for( $i = 0; $i < count ($somearray); $i++ )
 {
 $somearray[$i] .= "($i )";
 }
?>

Answer options D and A are incorrect. A while loop or a do while loop may also work. However, the array is sequentially indexed, the for each loop will be the best choice to accomplish the task.
