Why won't PHP do a simple addition problem? (2+1=21)?

[Tony121076]

The following lines of code all produce 21 instead of 3, why? I understand whats it's doing, but how can you do addition problems?

-------------------------
$mo = intval(date("j"));
$mo = ++$mo;
returns 21
-------------------------
$mo = date("j") + 1;
returns 21
-------------------------
$mo = intval(date("j")) + 1;
returns 21

dude, it is the 20th of february...not the 2nd (so 20+1=21)

Were you confused on the date function? He could had thought that it would return the month and not the day of the month.

passing 'j' gives you the day of the month.

oops. Thank you. I thought j was the month. I can't believe something so simple cost me so much time.

yeah those things are a bitch ...it's always the small things that takes loads of time to make it right
