To find out the current year is leap year or not which
date() function we've to use.Give the syntax also

Answer

to check the current year code is :

date("L");
output will be 1 coz 2008 is a leap year.

better way to check is :

$year=2008;
echo date("L",mktime(1,1,1,1,1,$year));
now you can check any year by just changing the value of
variable $year, this is called dynamic programming.
