How do I remove backslash from users input

Question

I'm getting blur to this one :P

function escape($string)
{
    $string = stripslashes($string);

    if (function_exists('mysql_real_escape_string')) {
       return mysql_real_escape_string($string, $this->connection);
    } else {
        return mysql_escape_string($string);
    }
}

$content = '""""""test\'te%%%%st`test_huhu\'_';

echo '<br>output 1 = '.stripslashes($content);
echo '<br>output 2 = '.$db->escape($content);

The output

output 1 =  """"""test'te%%%%st`test_huhu'_
output 2 =  \"\"\"\"\"\"test\'te%%%%st`test_huhu\'_ 

How to make output 2 will be same like output 1 and why the output 2 to be like that?

Answer 1

mysql_real_escape_string escapes all " and ' that's why you get all those slashes. If you remove the slashes before putting the data in a database you're open for attacks which is very bad for security dont you think?
