mysql_escape_string — Escapes a string for use in a mysql_query
This function was deprecated in PHP 4.3.0, and it and the entire original MySQL extension was removed in PHP 7.0.0. Instead, use either the actively developed MySQLi or PDO_MySQL extensions. See also the MySQL: choosing an API guide. Alternatives to this function include:
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.
unescaped_stringThe string that is to be escaped.
Returns the escaped string.

mysql_escape_string() does not escape
%and_.
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.
