SYNOPSIS
       Warning

	      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:

		     omysqli_character_set_name(3)

       string mysql_client_encoding ([resource	$link_identifier = NULL])

DESCRIPTION
	Retrieves the character_set variable from MySQL.

	      o $
		link_identifier -The MySQL connection. If the link identifier is not specified,  the  last  link  opened  by  mysql_connect(3)	is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	      mysql_client_encoding(3) example

	      <?php
	      $link    = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      $charset = mysql_client_encoding($link);

	      echo "The current character set is: $charset
";
	      ?>
