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

$offset = date('Z'); //timezone offset in seconds

if (floor(($UNIX_TIMESTAMP + $offset) / 86400) == floor((mktime(0,0,0) + $offset) / 86400)){
    echo "today";
}
