复制程式
<?
echo "===================完整无误的连接=================<br>";
mysql_connect("localhost","bbb","ccc");
echo "===================连接server位置错误=================<br>";
mysql_connect("111.111.111.111","bbb","ccc");
echo "===================server与user正确，但passwd错误=================<br>";
mysql_connect("localhost","bbb","xxx");
