[ohdang888]

what is wrong with this function?

 

function dbclean($string)

{

$string= mysql_real_escape_string(trim($string));

}

 

i'm not getting any errors, but its not wokring

[BlueSkyIS]

function dbclean($string)
{
     $string= mysql_real_escape_string(trim($string));
     return $string;
}

/// in use
$a_string = dbclean($a_string);

[ohdang888]

would it work if i just used this:

 

function dbclean($string)

{

    mysql_real_escape_string(trim($string));

    return $string;

}

 

no = sign

and then do:

 

$id = dbclean($raw)
