在实际教学应用中

<?php
function Connect_db($db_address,$db_port,$db_name,$db_owner,$db_pwd){
	$db_course = @mysql_pconnect("$db_address:$db_port",$db_owner,$db_pwd)
  		or die("错误报告：连接数据库失败!<br>" . mysql_error());
    if (!mysql_select_db($db_name,$db_course))
    	die("错误报告：不能打开数据库!<br>" . mysql_error());
	return ($db_course);
}
?>
