variable in a table name? 1

[altctrldel]

been fiddling with this for the past 2 hrs;

while($row = mysql_fetch_array($sql)){

$userid = $row['ws_id'];
$username = $row['ws_username'];
$password = $row['ws_password'];
$ipaddress = $row['ws_ipaddress'];
}

how do I insert a variable in the field names of the tables I want to get data from.

for example:

change 'ws_id' to '$level_id' <-- obsiously doesn't work

with the red text as the variable name. thank you again. ^^

$userid = $row[$level.'_id'];
