Scuze, nu vazusem.

Deci treaba e asa:

1) La prima rulare a programului nu ai apasat inca pe butonul ala "Create MD5 Hash", deci nu ai POST-at (trimis) formularul, deci variabila globala $_POST este goala, deci variabila $_POST['md5me'] nu exista
2) Initial testezi daca aceasta variabila exista inainte sa o folosesti

if (isset($_POST['md5me']))

, dar apoi renunti la asta si o folosesti, evident trebuia sa testezi iar

3) afiseaza tot timpul variabila $_POST ca sa intelegi ce si cum, ea nu se populeaza cu valori decat cand trimiti formularul

4) Dupa ce trimiti formularul, eroarea dispare, asa cum e corect.

<?php
error_reporting(-1);
ini_set('display_errors', 1);

var_dump($_POST);

$to_display = "not available yet";

//check if the form has been submitted
if (isset($_POST['md5me'])) {
   //MD5 encode the submitted content
   $md5ed = md5($_POST['md5me']);
   $to_display = $md5ed;
}
?>

<p>MD5 Value: <strong>
	 <?php echo $to_display; ?>
</strong>
</p>
<form action="#" method="post">
<label for="md5me">MD5 Me:</label>
<input name="md5me" id="md5me" type="text" />
<input type="submit" value="Create MD5 Hash" />
</form>
