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.

The exact characters that are escaped by this function are the null byte (0), newline (\n), carriage return (\r), backslash (\), single quote ('), double quote (") and substiture (SUB, or \032).
