die 提示的消息都去哪了?
小弟新手:
$fp=fopen("./readme.txt","r") or die("不能打开该文件");
想问下,如果打开失败,那么die 的这条消息输出到哪了啊?貌似打开失败界面也没有直接弹出这条消息?请问使用die这条消息自动会从服务器发到终端,然后在界面中弹出?
------解决方案--------------------
直接输出到浏览器
------解决方案--------------------
直接运行下面的code看看能不能输出123,如果可以,你就是fopen那个是正常的。
<br /><?php<br />die('123');<br />?><br />
die等于 echo xxx 然后 停止页面。
<br /><?php<br />$fp=fopen('','r') or die('123'); // 没有文件名,不可能打开,回转到die执行<br />?><br />
------解决方案--------------------
先不用ajax,直接用php看看能否輸出。如果可以,那問題就可以定位在js部分了。

错误显示功能没有打开不影响这个显示,反而打开了错误显示,会先显示PHP的出错信息,然后才是这个die出来的不能打开文件的提示。

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
