PHP URL label
有两张页面。index.html 和 index_do.php
index.html:
<form name="userlogin" action="/member/index_do.php" method="POST"> <label>帐 号</label><input type="text" name="userid"/> <label>密 码</label><input type="password" name="pwd"/> <input type="submit" value="立即登录" /></form>
PHP:怎样获取来自页面的提交地址?
因为index.html是被N张页面调用的。
比如以下页面调用了index.html提交了登录数据:
①、http://localhost/
②、http://localhost/works/
③、http://localhost/works/end/index.html
想要的结果:
index_do.php
//页面③中提交了登录数据
echo "你是从以下地址中登录的:"."http://localhost/works/end/index.html";
?>
求大神
回复讨论(解决方案)
$_SERVSR['HTTP_REFERER']
$_SERVSR['HTTP_REFERER']
取不出,空白。。。
再加一个隐藏的input,其值为action
建议你去看看PHP的$_SERVSR用法
直接在页面上把$_SERVSR打印出来看看也许会有更深刻的认识

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

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),
