PHP制作图型计数器的例子_php基础

以前在奥索看见过很多这样的例子，各各方法复杂，请看如下例子实现图形计数器。在网页中使用请用


//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 $cou="0".$cou;
$w++;
}
$www=strlen($cou);
$i=0;
echo "document.write(\"

\");\n";
while($i $ym=substr($cou,$i,1);
echo "document.write(\"\");\n";
$i++;
}
?>
