为什么 AJAX 里写入的 cookie 无法显示出来?
我在一个 send.php 里通过 ajax 的方式 写了这句 setcookie("ip",$ips,time()+3600,'/');
然后从另外一个页面 print_r($_COOKIE);
却看不到 cookie 数组里 的 ip 这个项目
何解?
------解决方案--------------------
检查下在对 cookie 进行赋值前还有没有其他输出?
------解决方案--------------------
贴出你的测试代码
------解决方案--------------------
测试打印 cookie 的 php
是在同一浏览器的不同选项卡中运行的吗?
如果不是,没有结果是正确的
一直到ajax运行的窗口关闭后,再刷新才会有结果(但也要在1小时以内)
------解决方案--------------------
道理很简单,
1、php能取到 cookie 是因为浏览器向php发送了cookie
2、php设置的cookie被浏览器保存在内存中
3、当浏览器退出,或转向其他网站时,尚未过期的cookie会保存到文件
4、浏览器进程间是不能通讯的,而cookie文件也未生成,当然也就看不到cookie了
希望我说明白了
------解决方案--------------------
session 只是将 sessionid 存放在 cookie 里,并且失效期为 0,即离开了就没有了
你自己想一下,该不该有
------解决方案--------------------
只要你的其他页面是从这个ajax页面跳转出去的,那么session都会存在
------解决方案--------------------
require dirname(__FILE__) . 'ipfun.php';
------解决方案--------------------
------解决方案--------------------
应该不是require的问题吧,方便的话把ipfun.php贴出来看看。还有就是用firefox或是chrome看一下cookie(sessionID)是否存在浏览器里了

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
