In php, how can I obtain the form value from the next page after being submitted using submit?

In php, after the form value is submitted using submit, how can I obtain the value of the checkbox on the next page? & nbsp; my php file contains the value of the check box, select "submit" of form to submit the value. after the data is submitted, send the value together with the data on the next page using socket. However, the value of the submit data cannot be obtained when it is sent using a socket. Currently, how can I obtain the form value in session php after it is submitted using submit on the next page?
My php file contains the checkbox value of the check box. I chose to use form submit to submit the value. I want to use socket to send the data together with the data on the next page after the data is submitted. However, the value of the submit data cannot be obtained when it is sent using a socket. Currently, both session and cookie are unavailable. I am a newbie. I hope some experts can help me solve this problem.

Print_r ($ _ POST );

I don't know if I understand it wrong. The data selected on the left and displayed on the right of the landlord should be in a table, or the data table on the right must have a selection device on the left, in addition, there should be a correspondence between the left and right sides, and submit a form directly on the right.
------ Solution --------------------
I don't quite understand what the landlord meant. if it's just a checkbox value
Assume that the checkbox is like this.

After submitting the request to another page
$ Zixun1 = $ _ POST ['zixun1'];
For ($ I = 0; $ I Echo $ zixun1 [$ I]."
