it's amzing when i send a null value in date() as a second parameter then it returns some time? how to remove this thing. i want that if a string is null or empty then doesn't do anything
$x=strtotime();
var_dump($x);
var_dump($x==NULL);
echo date('H:i',$x);
display
Warning: strtotime() expects at least 1 parameter, 0 given in
D:\xampp\htdocs\test\index.php on line 1
bool(false) bool(true) 05:30
It makes perfect sense. NULL equals 0 in this case. date() counts from 0, which was January 1st, 1970, 0:00:00 UTC.
You are based in Jaipur. Your timezone is UTC + 5:30 hours. Thus, date(0) on your server, in your time zone, will result in January 1st, 1970, 5:30.
Why not check the value of $x?
if($x != NULL)
echo date('H:i',$x);
insert into tbl_x(rank,open_time) in values('1',date('H:i',$x)),('2',date('H:i',$y)),('3',date('H:i',$z)); where open_time is time type field in mysql and $y and $z have some valueThe second parameter to the date() function is optional: if it's not provided, date() uses the current time. If you want to prevent this you have to check your variable before calling it, or write a wrapper function and use that instead of date().
