调用方式如下:其中DebugStr这个函数就是类似一个echo。
复制代码 代码如下:
DebugStr('$Adv->getContentById($id); $id为广告编号, 仅调用一条,返回内容为字符串');
echo Adv::getContentById(35);
DebugStr('$Adv->getContentByIdJS($id); $id为广告编号, 仅调用一条,返回内容为JS字符串');
echo Adv::getContentByIdJS(35);
DebugStr('$Adv->getContentByOrder($id); $id为广告编号, 仅调用ID倒序一条,返回内容为字符串');
echo Adv::getContentByOrder(4);
DebugStr('$Adv->getContentByOrderJS($id); $id为广告编号, 仅调用ID倒序一条,返回内容为JS字符串');
echo Adv::getContentByOrderJS(4);
echo '
';
类如下:
复制代码 代码如下:

$ReturnContent.= ' | ';

//如果为调用JS方式

The above introduces the PHP advertising calling code that supports Flash calling, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

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.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
