原先的数据结构是12个库 每个库里有100张表 以QQ群的聚簇方式存储
我做成新的结构，生成新关系表，预计是14亿数据（估计达不到也差不多），我想以QQ号大小来判断分别插入不同的库和表，有15个库，每个库100张表，总共1500张表，每张表存100万条数据，表已经生成了（图3），现在是插入数据，我昨天用PHP处理了下，一张表跑了将近15分钟，这样太慢，有没有更好的办法
这个是昨天做的程序，哪位大侠给点意见优化下，大神们帮帮忙，刚入职给的这个活儿，第三天了，做不出来要走人了

Beyond the Hype: Assessing PHP's Role TodayApr 12, 2025 am 12:17 AMPHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.
What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AMIn PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.
Explain the __invoke magic method in PHP.Apr 12, 2025 am 12:07 AMThe \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
Explain Fibers in PHP 8.1 for concurrency.Apr 12, 2025 am 12:05 AMFibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.
The PHP Community: Resources, Support, and DevelopmentApr 12, 2025 am 12:04 AMThe PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.
PHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AMPHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2.

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),
