Reverse string without strrev

Question

Some time ago during a job interview I got the task to reverse a string in PHP without using strrev.

My first solution was something like this:

Answer 1

you can try this..

$string = "NASEEM";
$total_word = strlen($string);      
for($i=0; $i<=$total_word; $i++)
{
   echo substr($string,$total_word-$i,1);
}
