This function will escape the <parameter>unescaped_string</parameter>,

This function is deprecated.

<para>
This function is identical to <function>mysql_real_escape_string</function>
except that <function>mysql_real_escape_string</function> takes a
connection handler and escapes the string according to the current
character set. <function>mysql_escape_string</function> does not take a
connection argument and does not respect the current charset setting.
