variables with mysql array

[viveleroi0]

I have the following database array:

				for($i = 0; $i < $InboxCount; $i++)
					{
						$Inbox_row = mysql_fetch_array($List_Inbox);

					echo"
					   <tr>
						 <td>
							 ".$Inbox_row['cust_order_date']."
						 </td>
						  <td>
							 ".$Inbox_row['cust_name']."
						 </td>
						  <td>
							 ".$Inbox_row['cust_email']."
						 </td>
						  <td>
							 ".$Inbox_row['cust_phone']."
						 </td>
					   </tr>";
				}
			}

but I want the field names to be variables that can be defined in another file (like a config file), for this:

".$Inbox_row['$cust_field']."

But that will not work - is there an easy way I can do that without all sorts of extra code?

That would work as long as $cust_field is defined and you don't use the single quotes.
