PHP session and multiple mixed PHP/HTML sections in one page
If I have a page with multiple <?php ... ?>
sections interspresed with pure HTML sections. I notice that a $_SESSION
varible set in one <?php ... ?>
section is not available in another on开发者_如何学运维 the same page.
So, what's the best practise?
1) call session_start()
as the first line of each <?php ... ?>
section?
2) only have one <?php ... ?>
section which covers the whole page? If so, I have to wrap each HTML section in echo
, which is annoying of they are HTML form elements. Maybe heredoc
them?
It's my first time to try this sort of thing, but I am not the first one to do so - what's the accepted best practise?
Edit: Aplogies, my stupid fault. One of the sections PHP started with <?
and not <?php

The sections of php tags <?php ... ?>
have nothing to do with session. Make sure that you put:
session_start()
on top of your page.
As long as you set the header before doing any output, you shouldn't have any issues with the session (as the function session_start() also set the header).
There is really no problem having multiple PHP sections on a page. But I would highly recommend, to do all the logic (reading from database, processing form data) in a separate file OR in the first section.
