php数据库连接

前言

最近在学习php，刚好学习到了php连接数据库记录一下

总结

 //1、与mysql建立连接$conn = mysql_connect("127.0.0.1","root","root");//设置编码mysql_set_charset('utf8');//2、选择要操作的数据库mysql_select_db("xuesheng");//3、进行增删改查$sql = "SELECT * FROM emp t1, bumen t2 where t1.b_id = t2.b_id";$result = mysql_query($sql);//var_dump($result);print_r(mysql_fetch_assoc($result));$list = array();while($row=mysql_fetch_assoc($result)){$list[] = $row;}echo "<pre>";print_r($list);echo "</pre>";//4、关闭连接mysql_close($conn);
