#########随机广告显示##########
function myads(){
$dir="ads"; #设置存放记录的目录
//$dir="ads"; #设置存放记录的目录
$ads="$dir/ads.txt"; #设置广告代码文件
$log ="$dir/ads.log"; #设置ip记录文件

$ads_lines=file($ads);
$lines=count($ads_lines);#文件总行数

####读出广告总数$ads_count和显示次数到数组$display_array########
$ads_count=0;
$display_count=0;
for ($i=0;$i if((!strcmp(substr($ads_lines[$i],0,7),"display"))){
$ads_count =1;
$display_array[$ads_count]=substr($ads_lines[$i],8);
$display_count =$display_array[$ads_count];
}
}
####决定随机显示序号$display_rand#####
srand((double)microtime()*1000000);
$display_rand = rand(1,$display_count);

###决定广告序号$ads_num######
$pricount=0;
$ads_num=1;
for($i=1; $i $pricount = $display_array[$i];
if ($display_rand }

#####播放广告代码#########
$num=0;
$flag=0;

for($i=0;$i if((!strcmp(substr($ads_lines[$i],0,7),"display"))){$num ;}
if(($num==$ads_num)and($flag==0)){$flag=1;continue;}
if(($flag==1)and strcmp($ads_lines[$i][0],"#")){echo $ads_lines[$i];continue;}
if(($flag==1)and(!(strcmp($ads_lines[$i][0],"#")))){break;}
}
####纪录广告显示次数#########
$fp=fopen($log,"a");
fputs($fp,date( "Y-m-d H:i:s " ).getenv("REMOTE_ADDR")."==>".$ads_num."\n");
fclose($fp);
}
?>

广告代码文件ads.txt

########每个广告代码之间用'#'隔开,display为显示加权数,越大显示次数越多################
