Re: Still trying to understand sessions?

Still confused. In my example below, formsave is an array which can contain multiple variables and can be access like $formsave['name'] for example, but from my understanding - $_SESSION['name'] only contains one variable - name. So in order to do the same thing as session_register using $_SESSION, would I have to use multiple instances? i.e.$_SESSION['name'] = "$POST['name'], $_SESSION['email'] = "$POST['email'], etc. I just don't understand the use of each of these. From what I see session_register seems to be the better option. Any thing else you can add to un-confuse me is appreciated. if (!session_is_registered("formsave")) { // Form Array session_register("formsave"); } TIA ----- Original Message ----- From: "Greg Beaver" <greg@chiaraquartet.net> To: "Matthew Walden" <mwalden@ukonline.co.uk> Cc: <php-general@lists.php.net>; "C.R." <odcs@rogers.com> Sent: Wednesday, April 23, 2003 8:38 PM Subject: Re: Still trying to understand sessions? > Hi, > > For PHP version 4.2.3+, use $_POST instead of $HTTP_POST_VARS, > $HTTP_POST_VARS is deprecated. > > register_session_variable() is only intended to extract $_SESSION array > contents into global variables. > > so, > > $_SESSION['myvar'] = 'hello'; > > is the same as: > > register_session_variable('myvar'); > $myvar = 'hello'; > > or even: > > extract($_SESSION); > $myvar = hello; > > Greg > -- > phpDocumentor > http://www.phpdoc.org > > Matthew Walden wrote: > > OK I'm no expert, but I've used sessions a few times so I'll try and > > share what I (think I) know. > > > > Firstly, you set session variables like this : > > > > session_start(); > > _SESSION['variable_one'] = $variable_one; > > _SESSION['variable_two'] = $variable_two; > > etc. > > > > Then, you can refer to these variables in any page which calls the > > session_start() function.
