调用方法：

<script language = "javascript" src = "count.php"></script>

count.php源码：

复制代码 代码如下:

<?php

$file_name = "count.txt";

$fp = fopen($file_name,"r"); //打开文件读入当前计数

$count = fread($fp, filesize($file_name));

fclose($fp);

$count++; //计数加1

$fp = fopen($file_name, "w"); //再次打开文件写入更新后的计数

fwrite($fp, $count);

fclose($fp);

echo "document.write('".$count."')"; //输出JavaScript代码，返回计数

?>
