使用curl获取地址的时候，显示Bad Request.但是这个地址在浏览器里有可以打开
使用curl获取地址的时候，显示Bad Request.但是这个地址在浏览器里有可以打开，程序也没有问题。采集别的网址是可以的
------解决方案--------------------
几种情况
1.远端有检测客户端过滤行为
2.远端有redir行为
3.请求中间层
4.近端有过滤行为
5.某个过程有缓存机制
6.未知
几种情况大致都是你并非直达“真实内容”
无终极解决方案，有的话，可以拿出来取笑一下某校长
------解决方案--------------------
我遇到过这种情况，就是没有获取到真是的地址！
可以试试firefox的插件httpfox，看看能否获取到真实地址，如果不行
你可以下载一个获取真实地址的软件试试。
PHP's Current Status: A Look at Web Development TrendsApr 13, 2025 am 12:20 AMPHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.
PHP vs. Other Languages: A ComparisonApr 13, 2025 am 12:19 AMPHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
PHP vs. Python: Core Features and FunctionalityApr 13, 2025 am 12:16 AMPHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.
PHP: A Key Language for Web DevelopmentApr 13, 2025 am 12:08 AMPHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
PHP: The Foundation of Many WebsitesApr 13, 2025 am 12:07 AMThe reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.
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.

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),
