  2. function getWeekName($data,$format = '星期')
  3. {
  4. $week = date( "D ",$data);
  5. switch($week)
  6. {
  7. case "Mon ":
  8. $current = $format."一";
  9. break;
  10. case "Tue ":
  11. $current = $format."二";
  12. break;
  13. case "Wed ":
  14. $current = $format."三";
  15. break;
  16. case "Thu ":
  17. $current = $format."四";
  18. break;
  19. case "Fri ":
  20. $current = $format."五";
  21. break;
  22. case "Sat ":
  23. $current = $format."六"; break;
  24. case "Sun ":
  25. $current = $format."日";
  26. break;
  27. }
  28. return $current;
  29. }
  31. echo '今天是：'.getWeekName(time(),'星期');
  32. echo '
    ';
  33. echo '今天是：'.getWeekName(time(),'礼拜');
  34. echo '
    ';
  35. echo '2010-12-12是：'.getWeekName(strtotime('2010-12-12'),'礼拜');
  36. ?>

4、获取类似文章发表的几小时前等效果的自定义函数

  2. function time2Units ($time)
  3. {
  4. $year = floor($time / 60 / 60 / 24 / 365);
  5. $time -= $year * 60 * 60 * 24 * 365;
  6. $month = floor($time / 60 / 60 / 24 / 30);
  7. $time -= $month * 60 * 60 * 24 * 30;
  8. $week = floor($time / 60 / 60 / 24 / 7);
  9. $time -= $week * 60 * 60 * 24 * 7;
  10. $day = floor($time / 60 / 60 / 24);
  11. $time -= $day * 60 * 60 * 24;
  12. $hour = floor($time / 60 / 60);
  13. $time -= $hour * 60 * 60;
  14. $minute = floor($time / 60);
  15. $time -= $minute * 60;
  16. $second = $time;
  17. $elapse = '';
  19. $unitArr = array('年' =>'year', '个月'=>'month', '周'=>'week', '天'=>'day',
  20. '小时'=>'hour', '分钟'=>'minute', '秒'=>'second'
  21. );
  23. foreach ( $unitArr as $cn => $u )
  24. {
  25. if ( $$u > 0 )
  26. {
  27. $elapse = $$u . $cn;
  28. break;
  29. }
  30. }
  32. return $elapse;
  33. }
  35. $past = 2052345678; // 发布日期
  36. $now = time(); // 当前日期
  37. $diff = $now - $past;//相差值
  39. echo '发表于' . time2Units($diff) . '前';
  40. ?>
复制代码

另一种，个人认为比较好的：

  2. function time_tran($the_time){
  3. $now_time = date("Y-m-d H:i:s",time()+8*60*60);
  4. $now_time = strtotime($now_time);
  5. $show_time = strtotime($the_time);
  6. $dur = $now_time - $show_time;
  7. if($dur < 0){
  8. return $the_time;
  9. }else{
  10. if($dur < 60){
  11. return $dur.'秒前';
  12. }else{
  13. if($dur < 3600){
  14. return floor($dur/60).'分钟前';
  15. }else{
  16. if($dur < 86400){
  17. return floor($dur/3600).'小时前';
  18. }else{
  19. if($dur < 259200){//3天内
  20. return floor($dur/86400).'天前';
  21. }else{
  22. return $the_time;
  23. }
  24. }
  25. }
  26. }
  27. }
  28. }
  29. ?>
复制代码

5. Calculate the time difference based on the difference between the two times.

  2. function getTime( $val ){
  3. if($val>0){
  4. $nTime['nDay'] = (int)($val/(3600*24));
  5. $nTime['nHour'] = (int)($val%(3600*24)/3600);
  6. $nTime['nMin'] = (int)($val%(3600*24)%3600/60 );
  7. $nTime['nSec'] = (int)($val%(3600*24)%3600%60);
  8. }
  9. return $nTime;
  10. }
  11. function getStrTime( $val ){
  12. $aTime = getTime($val);
  13. $dtoc = array('nDay'=>'day','nHour'=>'hour','nMin'=>'minute','nSec'=>'second ');
  14. if( $aTime ){
  15. foreach( $aTime as $k=>$v){
  16. if($v){
  17. $cTime .= $v.$dtoc[$k];
  18. }
  19. }
  20. }else{
  21. $cTime = 'Ended';
  22. }
  23. return $cTime;
  24. }
  25. ?>
