本文实例讲述了PHP常用函数之格式化时间操作。分享给大家供大家参考,具体如下:
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | /** * 格式化时间 * @param $time 时间戳 * @return bool|string */ function formatTimeToNow( $time ){ //获取现在的时间戳 $nowtime = time(); if ( $time > $nowtime ){ return '' ; } else { $tc = $nowtime - $time ; if ( $tc >= 864000 ){ $str = date ( 'Y-m-d H:i' , $time ); //如果大于10天,则直接显示日期 } else if ( $tc >= 86400){ $str = floor ( $tc /86400) . "天前" ; //如果大于1天 } else if ( $tc >= 3600) { $str = floor ( $tc / 3600) . "小时前" ; //如果大于1小时 } else if ( $tc >= 60) { $str = floor ( $tc / 60) . "分钟前" ; //如果大于1分钟 } else { $str = "刚刚" ; } return $str ; } } |
1 2 3 4 5 6 7 8 9 10 11 12 13 | /** * 将中文的日期格式化为正常的日期 * @param $date * @return mixed */ function formatCnDateToDate( $date ){ //把年月替换为-,日替换为空 $date = str_replace ( '年' , '-' , $date ); $date = str_replace ( '月' , '-' , $date ); $date = str_replace ( '日' , '' , $date ); //避免提交的格式不统一,例如2018-3-2等,标准化 return date ( 'Y-m-d' , strtotime ( $date )); } |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 | /** * 计算自然周期的开始时间戳和结束时间戳(周一到周日,月初到月末) * @param int $time_type 1表示自然天,2表示自然周,3表示自然月 * @param int $prev_num 距离现在的值(前一周传-1,前两周传-2...) * @return array|bool */ function naturalFormatTime( $time_type =1, $prev_num =0){ $today_start_time = strtotime ( date ( 'Y-m-d 00:00:00' ,time())); //今天0点的时间戳 if ( $time_type == 1){ if ( $prev_num == 0){ return array ( 'start_time' => $today_start_time , 'end_time' =>time(), 'show_date' => date ( 'Y年m月d日' ,time())); } else if ( $prev_num < 0){ $start_time = $today_start_time - 86400* abs ( $prev_num ); $end_time = $start_time + 86399; $show_date = date ( 'Y年m月d日' , $start_time ); return array ( 'start_time' => $start_time , 'end_time' => $end_time , 'show_date' => $show_date ); } else { return false; } } else if ( $time_type == 2){ $today_week = date ( 'w' , $today_start_time ); if ( $today_week == 0){ $today_week_start_time = $today_start_time - 86400*6; } else { $today_week_start_time = $today_start_time - 86400*( $today_week -1); } if ( $prev_num == 0){ $show_date = date ( 'Y年m月d日' , $today_week_start_time ); $show_date .= '至' . date ( 'd日' ,time()); return array ( 'start_time' => $today_week_start_time , 'end_time' =>time(), 'show_date' => $show_date ); } else if ( $prev_num < 0){ $start_time = $today_week_start_time - 86400*7 * abs ( $prev_num ); $end_time = $start_time + (86400*7-1); $show_date = date ( 'Y年m月d日' , $start_time ); $show_date .= '至' . date ( 'd日' , $end_time ); return array ( 'start_time' => $start_time , 'end_time' => $end_time , 'show_date' => $show_date ); } else { return false; } } else if ( $time_type == 3){ if ( $prev_num == 0){ $today_day = ltrim( date ( 'd' , $today_start_time ),0); $today_month_start_time = $today_start_time - 86400*( $today_day -1); $show_date = date ( 'Y年m月d日' , $today_month_start_time ); $show_date .= '至' . date ( 'd日' ,time()); return array ( 'start_time' => $today_month_start_time , 'end_time' =>time(), 'show_date' => $show_date ); } else if ( $prev_num < 0){ $start_time = strtotime ( date ( 'Y-m-01' , strtotime ( "$prev_num month" ))); $days = date ( 't' , $start_time ); $end_time = $start_time + 86400 * $days -1; $show_date = date ( 'Y年m月d日' , $start_time ); $show_date .= '至' . date ( 'd日' , $end_time ); return array ( 'start_time' => $start_time , 'end_time' => $end_time , 'show_date' => $show_date ); } else { return false; } } else { return false; } } |

希望本文所述对大家PHP程序设计有所帮助。
