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

Its Too Simple

//Reverse a String

$string = 'Basant Kumar';
$length = strlen($string);

for($i=$length-1;$i >=0;$i--){
    echo $string[$i];
}
