Convert date to string

[IgnaceV]

Ik have a database table "abbonees" (MariaDB) where I have among some textfields, following fields
date (current_timestamp on time of registration), type date
time ((current_timestamp on time of registration) type time
end date (date + 7 days) type date 
end time ( time + 2 hours)  type time
When I use this code

if ($_SESSION['pasw'] == $row["paswoord"]){
		$_SESSION['ingelogd']="J";
		$_SESSION['Naam']= $row["Naam"];
		$_SESSION['VNaam']= $row["Vnaam"];
		$_SESSION['edat']= $row["einddatum"];

When I try to login, Then I get this error: Warning: Undefined array key "einddatum" in /customers/1/5/0/fv-vl-ardennen.be/httpd.www/koepel/inlog.php on line 30 Warning: Cannot modify header information - headers already sent by (output started at /customers/1/5/0/fv-vl-ardennen.be/httpd.www/koepel/inlog.php:30) in /customers/1/5/0/fv-vl-ardennen.be/httpd.www/koepel/inlog.php on line 32
The first 3 are OK.
What do I wrong?

Try

echo '<pre>' . print_r($row, true) . '</pre>';

to see what indexes $row does have. (Note - they are case-sensitive)

I think that I know what I am doing wrong.

Array ( [IDR] => 5 [Naam] => Tester [Vnaam] => twee [mail] => service@ipathome.be [paswoord] => 314cfc36688da0847e6cbf7fe2961c96 )

Warning: Cannot modify header information - headers already sent by (output started at /customers/1/5/0/fv-vl-ardennen.be/httpd.www/koepel/inlog.php:30) in /customers/1/5/0/fv-vl-ardennen.be/httpd.www/koepel/inlog.php on line 32

I must extend my query.

Stupid that i Not have seen that. I learned a thing.

Not sure what that "array" is that you posted.  It sure isn't a valid PHP array.  Missing a lot of quotes and commas

Now it is working. Thank you very much.

Don't you think it could be the output from print_r()?

[ginerjm]

Didn't think of that way.
