UNIX timestamp function strtotime in php

echo strtotime ("now"), "n";
echo strtotime ("10 September 2000"), "n";
echo strtotime ("+1 day"), "n" ";
echo strtotime ("+1 week"), "n";
echo strtotime ("+1 week 2 days 4 hours 2 seconds"), "n";
echo strtotime ("next Thursday"), "n" ";
echo strtotime ("last Monday"), "n";
?>

Example 2,

$str = 'Not Good';
if (($timestamp = strtotime($str)) === -1) {
echo "The string ($str) is bogus ";
} else {
echo "$str == ".date('l dS of F Y h:i:s A',$timestamp);
}
?>

this The effect is the same as using mktime().
