Unable to show specific field data form MySQL db - php

Question

please ignore that it is old code im am testing
Having an issue where by I am unable to show specific user data from my db yet I can show the row of data. I can show the username using <?php echo htmlentities($_SESSION['username']); ?>but if I try and throw out email for example it dosnt like it. but if I do this....
<?php
$con = mysql_connect("localhost","***","***");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dmh", $con);
$result = mysql_query("SELECT * FROM members");
while($_SESSION = mysql_fetch_array($result))
{
echo $_SESSION['email'];
}
mysql_close($con);
?>
Like I say it chucks up the row - in regards to the above mention of pulling data from the DB via <?php echo htmlentities($_SESSION['username']); ?> this is handled by pulling in by db_connect.php file and also my functions file.

Try the following, unsure if that's the result you wish to get.
Using mysqli_* functions instead of mysql_*.
<?php
DEFINE ('DB_USER', 'xxx');
DEFINE ('DB_PASSWORD', 'xxx');
DEFINE ('DB_HOST', 'xxx');
DEFINE ('DB_NAME', 'xxx');
$mysqli = #mysqli_connect (DB_HOST, DB_USER, DB_PASSWORD, DB_NAME)
OR die("could not connect");
$result = mysqli_query($mysqli,"SELECT * FROM members ");
session_start();
while($row = mysqli_fetch_array($result))
{
$_SESSION['email']=$row['email'];
}
echo $_SESSION['email'];
echo "<hr>";
echo "TEST";
echo "<hr>";
var_dump($_SESSION['email']);
mysqli_close($mysqli);
?>

I wouldn't access the $_SESSION like that. You could try:
$result = mysql_query("SELECT * FROM members");
while($meh = mysql_fetch_array($result))
{
$_SESSION['email']=$meh['email'];
echo $meh['email'];
}
That way your other session variables don't get overridden when you go to this page. The only other thing that I can suggest is trying print_r($meh); to see what data is actually getting put in the array. If it's attaching to numbers, there's a high chance you need to access it like echo $meh[0].
