Question

When I save this string in PHP:

John: "Yes you can".

In my database is saved as:

John: \

How can I save these strings with ” ( without deleting ” obviously ).
This is my php code:

$titlepost= mysql_real_escape_string($_POST['title']);
$query = "INSERT INTO `titles` (`title`) VALUES ( '".$titlepost."')";
$res = mysql_query($query) or die("Failed".mysql_error() );

echo $titlepost;

output: 
John: \\

FORM:

$title = mysql_real_escape_string($_GET['title']);

<form method="post" action="title.php?done=yes" enctype="multipart/form-data">
<input type="text" size="25" name="title" <?php echo "value=\"".$title."\""; ?> > 
<input id="starit" name="submit" value="titleit" type="submit" />
</form>

Your problem has nothing to do with PHP or MysQL.

It is as silly as very simple HTML syntax rule.
It is quite obviously that the code

<input value="John: "YES you can>

will show only quoted “John: ” part.
To make it correct, one have to encode special symbols in the value

$titlepost = htmlspecialchars($titlepost,ENT_QUOTES);
?>
<input type="text" name="title" value="<?=$titlepost?>">

As for the slashes – it is silly excessive quoting issue. just quote your strings only once and make sure you have magic_quotes_gpc turned off
