    We're not going to simply do your work/homework for you. You'll have to show that you have at least put some research effort into this issue. Once you have tried something, come update this post with some code and a specific problem you are facing. – Lix Oct 03 '13 at 09:01

$str = "My Name is Khan";

$reverse = implode(" ",array_reverse(explode(" ", $str)));

echo $reverse;

Result is Khan is Name My.

explode splits the string into an array in accordance to the delimiter, which in this case is " ". array_reverse is self-explanatory, it reverses the order of the array. implode then joins the string using the delimiter.

You might think to code something to show then let us help you with the answer, but let me describe the logic, since you are going to input it as a string, you might think to split the character based on the character you wanted to split

you might consider this EXPLODE

After you finish and put that split into an array. You can reverse it back using looping or perhaps you want to reverse using THIS

  • This is the only acceptable answer here as it actually tried to teach the OP something as opposed to just giving the answer. – Lix Oct 03 '13 at 09:06

At first, requirement is: reverse the order of words not alphabets.

So, need to split the string by spaces(as words are separated by spaces).

This way, an array is generated like:

array('World', 'Hello');

Change the sequence of array using array_reverse()

The resulting array would be:

array('Hello', 'World');

Now, again join the above array by space:

The resulting string would be:

Hello World

Try this:

<?php
$name = 'World Hello';
$temp = explode(' ', $name);

echo '<pre>';
print_r($temp);
echo '</pre>';

$arr = array_reverse($temp);


echo '<pre>';
print_r($arr);
echo '</pre>';

$str = implode(' ', $arr);

echo $str;
?>
