Install php_curl extension support under window
1. Find php.ini
Modify extension=php_curl.dll and remove the semicolon in front;
Pay attention to the path of php.ini in the phpinfo() information
php_curl extension support under ubuntu linux
1. Create a new test.php file in the web server directory (usually /var/www under Ubuntu)
2. Edit the file and type the following line of code: phpinfo();
3. Save the file
4. Open the browser, Browse this page. (For example: http://localhost/test.php) 5. Search for "curl" to see if curl has been installed. If you don't find it, it must have not been installed. Please see below to install it.
The installation method is very simple and only requires one command. (I choose direct apt-get installation here, because it is much simpler than compiling by yourself, and you don’t need to configure anything yourself)
# sudo apt-get install curl libcurl3 libcurl3-dev php5-curl
Congratulations, PHP5 cURL is installed. Remember to restart the Apache server
# sudo /etc/init.d/apache2 restart
If you still have problems, try editing your php.ini file (mine is /etc/php5/apache2/php.ini) and add at the end One line: extension=curl.so Save the file and restart the Apache server.

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.
