if ($day_diff < 0 || $month_diff < 0) $year_diff–; -
return $year_diff; - }
计算执行时间
//Create a variable for start time - $time_start = microtime(true);
- // Place your PHP/HTML/JavaScript/CSS/Etc. Here
- //Create a variable for end time
$time_end = microtime(true); - //Subtract the two times to get seconds
$time = $time_end - $time_start; -
- echo 'Script took '.$time.' seconds to execute';

else if( $last == 3 ) $ext = 'rd'; - else if( $last == 2 ) $ext = 'nd';
else $ext = 'st'; -
if( $last == 1 && $seclast == 1) $ext = 'th'; - if( $last == 2 && $seclast == 1) $ext = 'th';
if( $last == 3 && $seclast == 1) $ext = 'th'; -
