You can use this function safely with your MySQL database queries if and only if you are sure that your database connection is using ASCII, UTF-8, or ISO-8859-* and that the backslash is your database's escape character. If you're not sure, then use mysqli_real_escape_string instead. This function is not safe to use on databases with multi-byte character sets.
The only benefit of this function is that it does not require a database connection.

Description
This function will escape the unescaped_string,
so that it is safe to place it in a mysql_query().
This function is deprecated.

The string that is to be escaped.
