@mmtuts
I am having trouble when I open this code. It works fine and reverses everything typed in as expected but I get the error:
Notice: Undefined index: text in C:xampphtdocsamberNewexp.php on line 9.
It goes away after first input. How to get rid of this error.



< ?php $val=$_GET['text']; echo strrev($val); ?>
