php 网页输出信息不全
我的php通过socket 接收服务端传过来的数据, 我看长度和server端传过来的字节数是相等的, 但是就是输出不全, 我通过htmlentities 输出的, 难道网页字节数还有限制么? 每次提交查询返回结果, 输出的信息总是少一些, 还不一定少多少, 比如第一次少1000多个字节, 下次有可能少2000个这样 该怎么解决呢?
我在php+apache环境下试验就正常, 用的xampp. 在linux环境, nginx+php+php-fpm就不行, 输出不全,是什么地方设置有问题么?
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.

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),
