ma il linguaggio do php4 è diverso da php5 ?

[prinzart]

questo invece è il form di login:

<table width="530" border="0" cellspacing="0" cellpadding="0">
<form action="<?=$PHP_SELF?>" method="post" name="form_login">






<?php if ($msg_login){?>
<tr>
<td width="530" colspan="9">
<span class="testo_rosso_bold"><?=$msg_login?></span>
</td>
</tr>
<?php }
else {?>

<?php }?>


<?php
$msgout = $_GET['msgout'];


if ($msgout){?>
<tr>
<td width="530" colspan="9">
<span class="testo_rosso_bold"><?=$msgout?></span>
</td>
</tr>
<?php }
else {?>

<?php }?>






<tr>
<td width="115"> </td>
<td width="20"></td>
<td width="72">
<a href="index.php" target="_top"><img src="images/pulsante_piccolo_home_72x22.gif" width="72" height="22" border="0" /></a>
</td>
<td width="20"></td>
<td width="72"><input name="image" type="image" value="SubmitForm" src="images/pulsante_piccolo_entra_72x22.gif" width="72" height="22"></td>
<td width="20"></td>
<td width="96"><input type="text" name="username" value="<?=$_POST['username']?>" size="15" maxlength="30" height="10"></td>
<td width="20"></td>
<td width="95"><input type="password" name="password" value="<?=$_POST['password']?>" size="15" maxlength="30" height="10"></td>

</form>
