Question

Between GET and POST method in PHP which is more secure and why

Answer 1

(WIKIPEDIA)

GET requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause.

and

POST submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both.

Answer 2

POST is more secure than GET.

www.yourpage.com/index.html?id=35&customdata=something
