Check if timestamp is today

Question

I\'ve got a timestamp in the following format (Which can easily be changed thanks to the beauties of PHP!).

2011-02-12 14:44:00

Answer 1

I prefer to compare timestamps (rather then date strings), so I use this to check today.

$dayString = "2011-02-12 14:44:00";
$dayStringSub = substr($dayString, 0, 10);

$isToday = ( strtotime('now') >= strtotime($dayStringSub . " 00:00") 
          && strtotime('now') <  strtotime($dayStringSub . " 23:59") );
