Article Introduction：There are three common ways to get file extensions in PHP: use the pathinfo() function, the combination of exploit() and end(), and regular expressions. 1.pathinfo() is the most recommended method, with clear logic and strong compatibility, and can correctly handle multipoint file names, such as 'example.tar.gz' returns 'gz'; 2. Explode() and end() are suitable for simple scenarios, but cannot accurately handle multipoint file names, such as 'example.tar.gz', will return 'gz' incorrectly; 3. Regular expressions are suitable for scenarios where extension format needs to be verified. Illegal characters can be filtered to ensure that the extension only contains legal characters. When selecting a method, you should pay attention to it according to the specific needs.

Article Introduction：The file extension is a suffix at the end of the file name and is used to indicate the file type. It is usually located after a point after a file name, such as .docx or .jpg, which helps computers and users identify how to process files.
