这是一篇php入门教程,讲得就是关于php 连接数据库并显示所要的数据,也就是简单的php+mysql数据库在web网页上的应用实例了,代码如下:
- <?php
- $Host="localhost";
-
- $MySQL_UserName="root";
-
- $MySQL_UserPass="password";
-
- $MySQL_Database="db";
-
- $Query="SELECT * FROM domain";
-
- if (!mysql_connect ($Host, $MySQL_UserName, $MySQL_UserPass)){
-
- print "Cannot connect to MySQL: ".mysql_error();
-
- exit;
-
- }
-
- if (!mysql_select_db ($MySQL_Database)){
-
- print "Cannot select db<BR>";
-
- exit;
-
- }
-
- if (!$Result_ID=mysql_query ($Query)){
-
- print "Query Error: ".mysql_error();
-
- exit;
-
- }
-
- while ($Result=mysql_fetch_row($Result_ID)){
-
- print "------------------<BR>";
-
- print "$Result[0]<BR>";
-
- print "$Result[1]<BR>";
-
- print "$Result[2]<BR>";
-
- print "$Result[3]<BR>";
-
- print "-------------------<BR>";
-
- }?>
