Implement advertising click rate statistics php code

Let’s create the database first.

CREATE TABLE IF NOT EXISTS `ad_count` (
`ad_id` int(8) NOT NULL auto_increment,
`ad_hit` int(8) NOT NULL default '0',
`ad_name` varchar(200) character set gb2312 default NULL,
`ad_datetime` datetime default NULL,
`ad_qq` varchar(15) character set gb2312 default NULL,
`ad_url` varchar(900) character set gb2312 NOT NULL,
`ad_price` int(8) NOT NULL,
PRIMARY KEY (`ad_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;

After the data is created, we start writing the program. I will not write the data connection,

<?php
 require_once("......省了");
 $ad_id =get_value(&#39;ad_id&#39;,&#39;&#39;);这里下面有讲
 if(is_numeric( $ad_id ) ){
 
  $ad_select="select ad_id,ad_url from ad_count where ad_id=&#39;$ad_id&#39; limit 1";  
  $ad_update="Update ad_count set ad_hit=ad_hit+1 where ad_id=&#39;$ad_id&#39; limit 1";
  
  $ad_result=mysql_query($ad_select) or die(&#39;id error&#39;);
  
   if( mysql_num_rows( $ad_result) ){   
    mysql_query($ad_update);    
    $ad_rs=mysql_fetch_array($ad_result);    
    header("location:".$ad_rs[&#39;ad_url&#39;]);    
    mysql_free_result($ad_rs);       
   }
 }

function htmltohtml($Str){
 $temp =str_replace(chr(13),&#39;<br/>&#39;,$Str);
 $temp =str_replace(&#39;<&#39;,&#39;<&#39;,$Str);
 $temp =str_replace(&#39;>&#39;,&#39;>&#39;,$Str);
 $temp =addslashes($Str);
 return $temp;
 }
 function get_value($value,$para){ 
 return htmltohtml(empty($para)?(isset($_GET[$value])?$_GET[$value]:&#39;&#39;):(isset($_POST[$value])?$_POST[$value]:&#39;&#39;));
 }

Then we write as follows where we want to display ads.

< ;img src=/ad_a/ad2.gif border=0 />

That’s it
