What are the differences between GET and POST methods in PHP?

GET and POST are two common methods used to send data from a form to a server in PHP. The main differences between them are:

• Security: POST is more secure than GET as the data is sent in the HTTP request body rather than the URL, which can be seen by users.
• Data Length: GET has a limitation on the amount of data that can be sent, whereas POST has no such limitation.
• Caching: GET requests can be cached by browsers, which may lead to security issues, while POST requests are not cached.
• Visibility: Data sent using GET is visible in the URL, while POST data is not visible to users.

Understanding these differences can help developers choose the appropriate method based on the requirements of their application.
