Sessions

[AxisC]

Hi everyone,

I have just started using PHP and MySQL for a project, and whilst i have plenty of coding and web design experience in HTML, javascript, actionscript and lingo, this is my first jump into dynamic content using a database and server side scripting language, so bear with me please!! 🙂 thanks guys!!

I am having a few problems getting sessions to persist at present but am clueless as to why. I am using PHP4 with MySQL, and refering to the book - PHP and MYSQL web dev by Luke Welling, which seems to be revised for 4.3.

It tells me to use the commands :

session_start();
$HTTP_SESSION_VARS['lang'] = "ENG";

but this renders the error :

Warning: session_start(): Cannot send session cookie - headers already sent

What i am trying to do is make a site multilanguage, pulling articles in the relevant language off the DB. For this though i need the $lang variable to remain reachable throughout the session. I have double / triple checked the documentation and i cant get anything to work. Any ideas??

Thanks in advance!!

Make those the first two lines of the script. The "headers already sent" error means you have output already, and your trying to use a header-type function(which all need to be called before any output).

Code Etiquette:

Use the superglobal $SESSION instead of the deprecated $HTTP_SESSION_VARS. Plus $SESSION is an auto global.

Cheers guys. I have been reading more into it and i now understand why $_SESSION is a better way to reference global variables, i hadnt realised this was a replacement for the method i was using. Have moved the session_start() function so that it fires before any output is rendered and it works great. Always the little things eh?? 🙂

Thanks for your help, i'm liking php already, i'm sure i'll be back for help all too often!! Cheers!!!
