本文实例讲述了CI(CodeIgniter)简单统计访问人数实现方法。分享给大家供大家参考,具体如下:
废话不说,先上代码:
控制器文件:
/application/controllers/hello.php 如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19

<?php if ( ! defined( 'BASEPATH' )) exit ( 'No direct script access allowed' );
class Hello extends CI_Controller {
public function index()
{
echo "Hello CodeIgniter!" ;
}
public function showval( $name ){
//访问路径:http://localhost/ci/index.php/hello/showval/Tom
$this ->name= $name ;
@ $num = file_get_contents ( './num.txt' ); //加上@屏蔽警告提示(第一次运行没有TXT文件会有警告提示)
$num = $num ? $num :0;
$num ++;
$arr = array ( 'v_name' => $name , 'v_num' => $num );
$re = fopen ( './num.txt' , 'w' );
fwrite( $re , $num );
fclose( $re );
$this ->load->view( 'test_views' , $arr );
}
}

视图文件:
/application/views/test_views.php 如下:
1
2
3
4
5
6
7
8
9
|
<html>
<head>
<meta http-equiv= "Content-Type" content= "text/html; charset=gb2312" />
<title>访问统计</title>
</head>
<body>
<?php echo $v_name ;?>是第 <?php echo $v_num ;?> 位访问者
</body>
</html>
|
运行结果如下图所示:
希望本文所述对大家基于CodeIgniter框架的PHP程序设计有所帮助。
