permissions

Hello, I'm trying to figure out a way to check for a user's database permissions (read, write). I've got my sql result as a single array - R W - (it's one column in the db). I want to check each array char , but I can't seem to get at the array contents. I'm very stuck. Hope the following is senseful... Thanks, Magnus Lawrie if (isset($sess_usr[2])) // if true then get permissions { $sql="SELECT rule FROM usr_tbl_ruls WHERE cftab_id=$fid AND usrgrp_id=$sess_usr[1]"; echo "$sql<br>"; $result=pg_exec($conn, $sql) or die ("failed to execute sql rules query"); $num = pg_numrows($result); for ($i=0; $i<$num; $i++) { $r = pg_fetch_row($result, $i); for ($j=0; $j<count($r); $j++) { echo "$r[$j]&nbsp;"; if ($r[$j] = R) { $read = true; echo $read; } else { $read = false; echo $read; } if ($r[$j] = W) { $write = true; echo $write; } else { $write = false; echo $write; } }
