Hello I am looking to get a day format of YYDDD i think it is a julian day.  

when i do

echo date("yz");
 
it gives me 04216, but with leap year the actual date is 04217.

Does anyone know how I can get the actual julian day?

z gives the day of the year starting with 0.  If you want it starting with 1, just add one.
echo date("yz") + 1;

try

$var = date("y");
$var2 = date("z");
$var2 = str_pad($input, 3, "0", STR_PAD_LEFT);
$out = $var.$var2;

echo $out;

sorry, should be

$var = date("y");
$var2 = date("z");
$var2 = str_pad($var2, 3, "0", STR_PAD_LEFT);
$out = $var.$var2;

echo $out;

There, what Diablo84 said, but you'll still need to increment it, otherwise the first day of the year will come out as 04000.

true, so...

$var = date("y");
$var2 = date("z") +1;
$var2 = str_pad($var2, 3, "0", STR_PAD_LEFT);
$out = $var.$var2;

echo $out;
