Article Introduction：Use PHP online compiler to be convenient and fast, suitable for testing code snippets or learning stages. The process includes: 1. Select a platform that supports new PHP version, has input and output windows, and can save code such as OnlineGDB, JDoodle or Replit; 2. Create a new PHP file in the editing area and write the code; 3. Click the Run button to view the execution results, such as outputting "Hello, world!". However, restrictions should be paid attention to: 1. Lack of a complete server environment and cannot configure Apache or Nginx; 2. File read and write permissions are limited; 3. Execution time may be limited, and scripts will be interrupted for a long time. For complete project development, it is recommended to build a local environment or use a cloud server.
