In addition to get post, which of the following is an effective method for transferring values between multiple pages? the variable is placed in a container during submission and can be accessed between pages, I used the session. I wrote it like this. on page A, we can print $ _ SESSION ["URL"] as abc, but the SESSION value cannot be accessed on page B:
