checking for null values

[Anon]

Hi,
I'm retrieving field values from a table.
How can I check whether a particluar filed value is null or not null?.
I tried using
if(isset($myrow[7)),
if($myrow[7)== "")
if($myrow[7)==null)

Nothing is working.
Can anyone help me out.Thanks in advance.

AS a start, you must use

$myrow[7], not $myrow[7)

and then, you can use the following:

if(!isset($myrow[7])) //Not very good one
if(empty($myrow[7])) //Better
if($myrow[7] == "") //Use == not =
if(isnull($myrow[7])) //Works sometimes

Hope it helps.

If you use
if($myrow[7)===null) (yes, three === !)
that will distinguish between 0, null and empty

let me know if it works!
