下面几行简单的代码即可实现PHP图形数字计数器，当然用asp也可以去实现的哦：

<?php
header("Content-Type:text/html;charset=utf-8");
if(!@$txt=fopen("img\/num.txt","r")){
$num=0;
}else{
$num=fgets($txt,10);
fclose($txt);
}
$num++;
$wtxt=fopen("img\/num.txt","w");
fwrite($wtxt,$num);
fclose($wtxt);
$numarr=str_split($num);
echo "您是本站第";
foreach($numarr as $img){
echo "<img src=\"img/".$img.".gif\" border=\"0\">";
}
echo "位访问者。";
?>

另外准备几张图片放到img目录下即可实现。
