php网站访问统计代码一例

1、统计页 count.php

<?php
/**
 * 网站访问统计
 * edit www.jb200.com
*/
function pageVisitCount(){
    $count= "count3.dat";
    $num= @file_get_contents($count);
    if ($fp= fopen($count,"w+")){
    flock($fp,LOCK_EX);
    $num++;
    fwrite($fp,$num);
    flock($fp,LOCK_UN);
    }
    return $num;
    }

    echo pageVisitCount();
?>

2、页面调用

<script type="text/javascript" src="http://localhost/count.php"></script>
