  说明:
  实现原理是:利用PHP的功能函数去读取文本文件的数据,从而实现数据的统计。

  1. 新建一个文件取名为:counter.php。代码如下:

//选择 counter.txt文本文件
$counter_file = ("counter.txt");
//打开文本文件
$visits = file($counter_file);
//自动加1
$visits[ 0]++;
//这个点击自动记录
$fp = fopen($counter_file , "w");
//写入counter.txt文件中,从而记录了
fputs($fp , "$visits[ 0]");
//关闭文件
fclose($fp);
//显示次数
echo $visits[0];
?>

  2. 把下面的代码代码放到你想显示点击次数的地方,达到文件显示目的。

include ("counter.php");
?>

  3. 最后新建一个文件counter.txt.修改其权限为 777。

  简单的计数器就实现了。
