实现原理很简单就是根据用户提交的数据到mysql数据表中查询是否有相同的,有就输出没有就不操作了,这是一款简单的记录搜索代码.

首先我们来创建搜索数据表:

create table if not exists `search` ( 
  `id` int(4) not null auto_increment, 
  `keyword` varchar(500) not null, 
  primary key  (`id`) 
) engine=myisam default charset=utf8 auto_increment=1 ;

保存数据,代码如下:

insert into `acc`.`search` ( 
`id` , 
`keyword`  
) 
values ( 
null , '内容搜索' 
), ( 
null , 'php站内搜索' 
);

数据连接,代码如下:

$conn = mysql_connect('localhost','ac','1');//这里的ac用户名,1是密码,修改成你自己的mysql便可 
$res = mysql_db_query('abc',"select * from search where keyword='内容搜索' ") or die(mysql_error()); 
if(mysql_num_rows($res) == 1) { 
   while($row = mysql_fetch_assoc($res)) { 
  foreach($row as $key => $val) { 
 echo $row[&#39;keyword&#39;],&#39;<br >&#39;; 
  }//开源代码phprm.com 
   } 
}
