What is the Difference Between `GET` and `POST` in PHP Forms?
Article Introduction：The choice of GET or POST depends on the data delivery method, security and operation type. 1. GET transmits data through URLs, which is visible and easy to be tampered with, and is suitable for scenarios where there is no sensitive information; POST places the data in the request body, which is more hidden and suitable for submitting sensitive information. 2.GET supports bookmarks and caching, which is suitable for search, filtering and other operations that do not change the server status; POST is not cached or bookmarked by default, which is suitable for logging in, uploading files, creating or modifying data. 3. GET is limited by the URL length, usually no more than 2048 characters, and is not suitable for large amounts of data or binary content; POST sends data through the request body, and there is no such restriction. 4. POST is more secure than GET, but both require HTTPS encryption to truly ensure security
