un altro esmpio

se io una file

codice:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body bgcolor="#FFFFFF" text="#000000">



testo1</p>
bnbnbnm


testo2</p>
</body>
</html>

e faccio:
ergi("

(.+)</p>", $file_string, $rges);
quello che ottengo:

array
(
[0] =>

testo1</p>
bnbnbnm

testo2</p>
[1] => testo1</p>
bnbnbnm

testo2
)

non mi riconosce le due occorrenze in maniera distinta ma fa una somma delle due

e giusto?
ciao
