PHP制作圖型計數器的例子

以前在奧索看見過很多這樣的例子,各各方法復雜,請看如下例子實現圖形計數器。在網頁中使用請用
<?
//存放計數的文本文件
$count="count.txt";
//計數器的位數,如果不填則默認為6位
$wei="";
//圖像的URL路徑
$tu="http://127.0.0.1/tcount/images";
?>
<?
if ($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);
$i=0;
echo "document.write("
");
";
while($i<$www) {
$ym=substr($cou,$i,1);
echo "document.write("");
";
$i++;
}
?>
