What are the various methods to pass data from one web page to another web page?

Question

I have two sessions I a workflow like below

workflow1->session1->session2

I have a join_date column in a table in Mapping1 , in session1. I want to pick this join_date value and pass to mpping2/session2

If join date value changes in the table in session1 then the same value should pick and pass to session2. I will use this date value in a query in session2 .

Please suggest how to achieve this?

Different methods to pass data from one web page to another:

1. Store the data in a session variable. By storing the data, the data can be passed from one page to another.

2. Store data in a cookie: By storing data in a persistent cookie, data can be passed from one form to another.

3. Set the data in a hidden field and post the data using a submit button.

Short note on passing parameter by reference and returning parameter by reference with examples.

Passing parameter by reference: In PHP, variables can be passed by reference so as to modify them. Variables, statements which have new and references returned from function can be passed.
