Article Introduction：To prevent PHP file upload vulnerabilities, you must first strictly control the uploaded content. 1. Always verify file types on the server side, use finfo_file() or mime_content_type() to check the real MIME type, and establish a whitelisting mechanism; 2. Do not trust user input and refuse to rely solely on front-end verification; 3. Rename the file after uploading, and use randomly generated file names to avoid execution risks; 4.
