<body>
<?php if(empty($_POST['n'])){ ?>
<form action="<?php echo $PHP_SELF; ?>" method="post">
<input type="text" name="n" value="" size="100" /><br /><center><input type="submit" value="Crea" /></center>
</form>
<?php }else{
$n = $_POST['n'];
$e = explode(" ",$n);
foreach($e as $var){
echo("<b>Lettera >> ".$var."</b>");
}
} ?>
</body>
</html>
