下面是我自己写的一个简单易行的计数器程序。你可以略加修改，用于你的个人主页。（另需一文件"counter.txt"，初始内容为计数器初始值。
<HTML>
<HEAD>
<TITLE> counter </TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF">
<?
$counterFile = "counter.txt";
function displayCounter($counterFile) {
$fp = fopen($counterFile,"rw");
$num = fgets($fp,5);
$num += 1;
print "<BR><BR><BR><BR><BR><BR><center>您是第 "."$num"." 个访问的家伙。</center>";
exec( "rm -rf $counterFile");
exec( "echo $num > $counterFile");
}
if (!file_exists($counterFile)) {
exec( "echo 0 > $counterFile");
}
displayCounter($counterFile);
?>
</BODY>
</HTML>
