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：
<?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：
<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：

Break or return from Java 8 stream forEach?
Feb 07, 2025 pm 12:09 PM
Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Java Program to Find the Volume of Capsule
Feb 07, 2025 am 11:37 AM
Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
