Please how do i create a session variable that will be used to search a database and display the users profile.

$_SESSION['var_name']="seun"

so ur sql will look something like

select * from users_tbl where where username="$_SESSION['var_name']"

Not forgetting to start your page with session_start() and all that. . .i assume you have sorted it all out iight?

Remember not to leave any white spaces before session_start();

<?php session_start();

// whatever code

?>

Interesting. . .i never knew space will stop it. . .i mean, i have never tried it before, to put space before it. . .by habit.
Mr poster, i hope you are writing down all of these!!

<?php


session_start();

// whatever code

?>

@Nitty, are u saying this is wrong?

i guess u meant to say, no output before session usage, output includes white spaces; carriage returns and line feeds
and that EXcludes white spaces within ur php codes

wat if they value is unknown that is the session doesn't have a value yet. webdezzi already gave it a value

well, i wonder why you will need a session without a value
just like buying a safe with no plans about using it

maybe u mean something similar to javascript variable definition

var webdezzi;
//then use webdezzi later


if that is what u mean, then sorry, php does believe in that theory
you dont have to declare a variable before using, if you must, then you can initialize it by assigning it to a default value
e.g
$_SESSION['var_name']=""; //for strings

$_SESSION['var_name']=0; //for ints, though you can cast on the fly

you can always use isset() to check the existence of any variable including sessions

if(isset($_SESSION['var_name'])) {do something}
