Question: I found that when the transaction has no commit or rollback, it will automatically rollback after the http request ends
Code example:
<code>$this->db->begin(); // 这时候user表这条记录就已经被锁住了。。。 $user = \Users::findFirst($id); $user->name = '写锁啊!'; sleep(15); $user->save(); return ; </code>
But when this request ends, the record in the database can be edited again. . .
I want to ask whether it is nginx, fpm or phalcon that automatically calls PDO->rollback(); ??????

MySQL's AUTOCOMMIT automatic submission parameter is turned on by default. It will only be submitted when a commit command is encountered in the transaction.
If it is operated through a MySQL driver in other languages, the MySQL driver will automatically ROLLBACK has no processed transactions.

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.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.

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),
