PHPStorm reported a 502 error when uploading files.
PhpStorm is a lightweight and convenient PHP IDE. It has an Apache-like compiler and can work without Apache. It can be run under PHPstrom, which is very suitable for friends who are new to PHPstrom.
But I discovered a problem, that is, when using PHPStrom for uploading, it will cause PHPStrom's own compiler to crash. When I first encountered this problem, I always thought it was an environmental problem, so I reinstalled the system. . Later, after repeated troubleshooting tests, it was found that environmental problems were not the cause.
Then how to solve this problem is to use the Apache compiler instead of the PHPstrom IDE compiler.
For example, the port number of PHPstrom is 63342, and the port number of Apache is 8080. Can you change the port number to the port number of Apache? Can this solve the problem?
No, it’s not possible yet, because Apache has a designated access path. There are two solutions. One is to move the file to the default path, or change the default path to the current file.
Modify the DocumentRoot C:/apache/htdocs in the path httpd.conf to the path of your current file, and that’s it.
Note: Let me say it again, because the program you start directly in phpstrom will use its own compiler. You can carefully check whether the port number of the browser has changed to 63342. Friends who have installed apache know that the port number of apache is definitely not this. So obviously, you are not accessing apache, so what should you do now? The first step is to install your development program in the apache running directory, which is the /apache/htdocs directory. The second step is to re-run the program and change the browser localhost: 63342 to your own apache port number. Then run it again. It should be able to run, and it's not a bad mistake to catch this error.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
