PHP show records from mysql - php

Question

Im blocked at following part of code...
i have config.php page, with following code inside:
<?php
// Start the session (pretty important!)
session_start();
// Establish a link to the database
$dbLink = mysql_connect('localhost', 'USER', 'PASS');
if (!$dbLink) die('Can\'t establish a connection to the database: ' . mysql_error());
$dbSelected = mysql_select_db('DATABASE', $dbLink);
if (!$dbSelected) die ('We\'re connected, but can\'t use the table: ' . mysql_error());
$isUserLoggedIn = false;
$query = 'SELECT * FROM users WHERE session_id = "' . session_id() . '" LIMIT 1';
$userResult = mysql_query($query);
if(mysql_num_rows($userResult) == 1){
$_SESSION['user'] = mysql_fetch_assoc($userResult);
$isUserLoggedIn = true;
}else{
if(basename($_SERVER['PHP_SELF']) != 'index.php'){
header('Location: index.php');
exit;
}
}
?>
Now i have another page, with following code inside:
<?php include_once('config.php'); ?>
<?php foreach($_SESSION['user'] as $key => $value){ ?>
<li><?php echo $key; ?> <strong><?php echo $value; ?></strong></li>
<?php } ?>
That code show me all informations stored in database, one by one..
I want to show informations, individualy in my page, something like:
<?php echo $email; ?>
etcetera..
Can someone explain me how to do that?
Thank you

Answer 1

You should output it like
<?php echo $_SESSION['user']['email'] ?>
assuming that 'email' is the column name in the users table.

Answer 2

Just address the relevant field in the associative array:
<?php echo $value['email';?>

Answer 3

Use this in the config file:
$_SESSION['user']['email'] = mysql_fetch_assoc($userResult);
instead of this
$_SESSION['user'] = mysql_fetch_assoc($userResult);
in your code. You can pass as many columns you want to pass from your table.
And in another page use
foreach($_SESSION['user']['email'] as $key => $value)
instead of
foreach($_SESSION['user'] as $key => $value)
in your code.
Remember number of columns you pass in config file, all those columns should be called in this page.
