$_SESSION

[arm207]

suppose I need the variable 'loginUsername' to be global to a sesssion.

so first thing i do,
session_register("loginUsername");


I have a showUserStatus() in another script that I want to print out the value in loginUsername. How do I use the $_SESSION variable to acutally get the value of loginUsername?

You might find this of interest.

Second session_register is now deprectaed, meaning is going out of use, and it is strongly suggested you use the $_SESSION variable instead.

like:

session_start();
$_SESSION['loginUsername']="Some_user";

...


The to get the value out, its just a matter of doing:

$myvar=$_SESSION['loginUsername'];

This will put the value of the loginUsername session var into $myvar.

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

thank you,

i see, and suppose when the user logs out, how shall I clear the $_SESSION['loginUsername'] value?

To unset a Variable you just issue the unset command.

session_start();
unset($_SESSION['loginUsername']);

or to clear the entire session
$_SESSION = array();

Don't forget you do need session_start(); on the top of every page which uses sessions, and also consider wheither or not you're concerned about non-cookie using users.
