PHP制作图型计数器的例子

//存放计数的文本文件

$count="count.txt";

//计数器的位数，如果不填则默认为6位

$wei="";

//图像的URL路径

$tu="http://127.0.0.1/tcount/images";

?>

if ($wei=="") { $wei=6; }

if (!file_exists($count)) { $fp=fopen($count,"w+"); fputs($fp,0,100); fclose($fp); }

if ($REMOTE_ADDR!=$ip){

$fp=fopen($count,"r+");

$cc=fgets($fp,100);

$cc=trim($cc);

if ($cc=="") { $cou=1; }

else { $cou=$cc+1; }

rewind($fp);

fputs($fp,$cou,100);

fclose($fp);

}

setcookie("ip",$REMOTE_ADDR,time()+86400);

$fp=fopen($count,"r+");

$cou=fgets($fp,100);

$cou=trim($cou);

fclose($fp);

$w=strlen($cou);

while($w<$wei) {

$cou="0".$cou;

$w++;

}

$www=strlen($cou);

$i=0;

echo "document.write("

");n";

while($i<$www) {

$ym=substr($cou,$i,1);

echo "document.write("");n";

$i++;

}

?>
