try to insert data...

hi,

i try to insert data in a database

$mem_nomembre = $_SESSION["mem_nomembre"];
$sec_nosection = $_POST['sec_nosection'];
$str = $_POST["message"];
$str = preg_replace_callback('`\[(code|url|img)\](.+?)\[/\1\]`si',
'bbcode', $str);
$str = mysql_real_escape_string($str);

mysql_query("insert into message (sec_nosection, mem_nomembre,
mes_titre, mes_message) values ('".$_POST['sec_nosection']."',
'".$mem_nomembre."', '".$_POST["titre"]."', '".$str."')");

if i try to insert: j'ai l'impression en parcourant le web

when i display the message i get: j\'ai l\'impression en parcourant le
web

if i put: stripslashes after mysql_real_escape_string, there are some:
rn in the sentence...

how to correct that?

when i insert a message, if i write

today is hot.
i like swimming.


i would like to get the same result...

now that display me:

today is hot. i like swimming.

if i do:

$str = preg_replace_callback('`\[(code|url|img)\](.+?)\[/\1\]`si',
'bbcode', $str);
$str = nl2br($str);
$str = mysql_real_escape_string($str);

i get:

today is hot.

i like swimming.

how to get this result?

thanks
