工作的過程中經常會遇到各種時間類的操作，因此封裝了一個幫助工具類，提高代碼的復用率

主要功能

根據相差的天數獲取連續的時間段

/** * 根據相差的天數獲取所有連續的時間段 * @param $diffDay * @param string $dateFormat * @return array html' target='_blank'>public static function getContinuesDayDiffDay($diffDay, $dateFormat = Y-m-d ) { $today = date( Y-m-d  $timeLabel = []; for ($i=1;$i =$diffDay;$i++){ $diff = $diffDay - $i; $mday = date($dateFormat,strtotime( $today -$diff day )); array_push($timeLabel,$mday); //轉化查詢條件 $year = date( Y  $startDay = str_replace( . , - ,$timeLabel[0]); $endDay = str_replace( . , - ,$timeLabel[$diffDay-1]); $startTime = strtotime($startDay. 00:00:00  $endTime = strtotime($endDay. 23:59:59  return [ start_time = $startTime, end_time = $endTime, time_label = $timeLabel, }

根據兩個日期獲取連續的時間段

/** * 根據開始和結束時間獲取所有連續的時間段 * @param string $startDay 開始日期 格式：Y-m-d * @param string $endDay 開始日期 格式：Y-m-d * @param string $dateFormat * @return array public static function getContinuesDayByRange($startDay, $endDay, $dateFormat = Y-m-d ) { $timeLabel = []; if(strtotime($startDay) strtotime($endDay)){ $tmp = $startDay; $endDay = $tmp; $startDay = $endDay; if($startDay == $endDay){ array_push($timeLabel,$startDay); $startTime = strtotime($startDay. 00:00:00  $endTime = strtotime($endDay. 23:59:59  $timeLabel = [ start_time = $startTime, end_time = $endTime, time_label = $timeLabel, return $timeLabel; $targetDay = $startDay; while ($targetDay != $endDay){ array_push($timeLabel,$targetDay); $targetDay = date($dateFormat,strtotime( $targetDay +1 day )); array_push($timeLabel,$endDay); //增加 $startTime = strtotime($startDay. 00:00:00  $endTime = strtotime($endDay. 23:59:59  $timeLabel = [ start_time = $startTime, end_time = $endTime, time_label = $timeLabel, return $timeLabel; }

根據日期獲取當月的開始時間和結束時間

 /** * 根據日期獲取本月的開始時間和結束時間 * @param $date Y-m 2017-10 * @return array public static function getMonthDaysByDate($date) { $data = []; $timestamp = strtotime( $date ); $data[ start_time ] = date( Y-m-01 00:00:00 , $timestamp ); $mdays = date( t , $timestamp ); $data[ end_time ] = date( Y-m- . $mdays . 23:59:59 , $timestamp ); return $data; }

時間友好格式化風格

/** * 時間友好型提示風格化（即微博中的XXX小時前、昨天等等） * 即微博中的 XXX 小時前、昨天等等, 時間超過 $time_limit 后返回按 out_format 的設定風格化時間戳 * @param int * @param int * @param string * @param array * @param int * @return string public static function getFriendlyTime($timestamp, $timeLimit = 604800, $out_format = Y/m/d , $formats = null, $now = null){ /*if (get_setting( time_style ) == N ) return date($out_format, $timestamp); if (!$timestamp) return false; if ($formats == null) $formats = [ YEAR = %s 年前 , MONTH = %s 月前 , DAY = %s 天前 , HOUR = %s 小時前 , MINUTE = %s 分鐘前 , SECOND = %s 秒前  $now = $now == null ? time() : $now; $seconds = $now - $timestamp; if ($seconds == 0) $seconds = 1; if (!$timeLimit OR $seconds $timeLimit) return date($out_format, $timestamp); $minutes = floor($seconds / 60); $hours = floor($minutes / 60); $days = floor($hours / 24); $months = floor($days / 30); $years = floor($months / 12); if ($years 0) $diffFormat = YEAR  else if ($months 0) $diffFormat = MONTH  else if ($days 0) $diffFormat = DAY  else if ($hours 0) $diffFormat = HOUR  else $diffFormat = ($minutes 0) ? MINUTE : SECOND  $dateDiff = null; switch ($diffFormat) case YEAR : $dateDiff = sprintf($formats[$diffFormat], $years); break; case MONTH : $dateDiff = sprintf($formats[$diffFormat], $months); break; case DAY : $dateDiff = sprintf($formats[$diffFormat], $days); break; case HOUR : $dateDiff = sprintf($formats[$diffFormat], $hours); break; case MINUTE : $dateDiff = sprintf($formats[$diffFormat], $minutes); break; case SECOND : $dateDiff = sprintf($formats[$diffFormat], $seconds); break; return $dateDiff; }

根據日期獲取是星期幾

/** * 獲取星期幾 * @param $date * @return public static function getWeekDay($date) { //強制轉換日期格式 $dateStr=date( Y-m-d ,strtotime($date)); //封裝成數組 $arr=explode( - , $dateStr); //參數賦值 $year=$arr[0]; //月，輸出2位整型，不夠2位右對齊 $month=sprintf( %02d ,$arr[1]); //日，輸出2位整型，不夠2位右對齊 $day=sprintf( %02d ,$arr[2]); //時分秒默認賦值為0； $hour = $minute = $second = 0; //轉換成時間戳 $strap = mktime($hour,$minute,$second,$month,$day,$year); //獲取數字型星期幾 $numberWk=date( w ,$strap); //自定義星期數組 $weekArr=array(7,1,2,3,4,5,6); //獲取數字對應的星期 return $weekArr[$numberWk]; }

/** * 獲取指定日期前后相同時間天數的范圍時間 * @param int $dayDiff * @param string $day * @param string $dateFormat * @return array public static function getPointDaySameRangeContinuesTime($dayDiff = 0,$day = , $dateFormat = Y-m-d ) { $day = $day?$day:date($dateFormat); $startTime = date($dateFormat,strtotime( $day -$dayDiff day )); $endTime = date($dateFormat,strtotime( $day +$dayDiff day )); $result = self::getContinuesDayByRange($startTime,$endTime,$dateFormat = Y-m-d  return $result; }

獲取兩個日期之間相差的天數

/** * 獲取兩個日期之間相差的天數 * @param string $day1 第一個日期，格式為Y-m-d * @param string $day2 第二個日期，格式為Y-m-d * @return integer public static function getDiffBetweenTwoDays($day1, $day2) { $second1 = strtotime($day1); $second2 = strtotime($day2); if ($second1 $second2) { $tmp = $second2; $second2 = $second1; $second1 = $tmp; return ($second1 - $second2) / 86400; }

根據指定日期和天數，獲取結束的日期

/** * 根據日期和相差的天數獲取結束的天數 * @param $day * @param $diffDay * @param bool $isBefore * @return false|string public static function getEndDayByDayAndDiff($day, $diffDay, $isBefore = false) { $operator = $isBefore ? - : +  $endDay = date( Y-m-d ,strtotime( $day $operator $diffDay day )); return $endDay; }

判斷兩個日期是否為同一天

/** * 判斷兩個時間是否同一天 * @param string $date1 Y-m-d * @param string $date2 Y-m-d * @return bool public static function isSameDay($date1, $date2) { $day1 = self::dateTime(strtotime($date1)) ; $day2 = self::dateTime(strtotime($date2)); return $day1 == $day2; }

轉換秒鐘為分鐘

/** * 轉換秒鐘為分鐘 * @param $seconds * @return string public static function convertSecondToTime($seconds) { $reminded = strval($seconds % 60); $minute = strval(($seconds - $reminded) / 60); if(strlen($minute) 2){ $minute = 0 .$minute; if(strlen($reminded) 2){ $reminded = 0 .$reminded; $time = $minute. : .$reminded; return $time; }

獲取毫秒數

/** * 獲取時間的毫秒數 * @return float public static function millisecond() { list($msec, $sec) = explode( , microtime()); return (float)sprintf( %.0f , (floatval($msec) + floatval($sec)) * 1000); }
