mysql_escape_string — Escapes a string for use in a mysql_query
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
Description
$unescaped_string
)
This function will escape the unescaped_string,
so that it is safe to place it in a mysql_query().
This function is deprecated.
This function is identical to mysql_real_escape_string() except that mysql_real_escape_string() takes a connection handler and escapes the string according to the current character set. mysql_escape_string() does not take a connection argument and does not respect the current charset setting.
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
Parameters
-
unescaped_string -
The string that is to be escaped.
Return Values
Returns the escaped string.

Коментарии
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.
