這篇文章帶給大家的內容是關於PHP實現的時間幫助類別 (程式碼範例),有一定的參考價值,有需要的朋友可以參考一下,希望對你有幫助。
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,提高程式碼的複用率
主要功能
根據相差的天數取得連續的時間段
/** * 根据相差的天数获取所有连续的时间段 * @param $diffDay * @param string $dateFormat * @return array */ public static function getContinuesDayDiffDay($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); } //转化查询条件 $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, ]; }
根據兩個日期取得連續的時間段
/** * 根据开始和结束时间获取所有连续的时间段 * @param string $startDay 开始日期 格式:Y-m-d * @param string $endDay 开始日期 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; }
##根據日期取得當月的開始時間和結束時間
/** * 根据日期获取本月的开始时间和结束时间 * @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; }
時間友善格式化風格
/** * 时间友好型提示风格化(即微博中的XXX小时前、昨天等等) * 即微博中的 XXX 小时前、昨天等等, 时间超过 $time_limit 后返回按 out_format 的设定风格化时间戳 * @param int * @param int * @param string * @param array * @param int * @return string */ public static function getFriendlyTime($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 小时前', 'MINUTE' => '%s 分钟前', '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; }
根據日期取得是星期幾
/** * 获取星期几 * @param $date * @return */ public static function getWeekDay($date) { //强制转换日期格式 $dateStr=date('Y-m-d',strtotime($date)); //封装成数组 $arr=explode("-", $dateStr); //参数赋值 //年 $year=$arr[0]; //月,输出2位整型,不够2位右对齐 $month=sprintf('%02d',$arr[1]); //日,输出2位整型,不够2位右对齐 $day=sprintf('%02d',$arr[2]); //时分秒默认赋值为0; $hour = $minute = $second = 0; //转换成时间戳 $strap = mktime($hour,$minute,$second,$month,$day,$year); //获取数字型星期几 $numberWk=date("w",$strap); //自定义星期数组 $weekArr=array(7,1,2,3,4,5,6); //获取数字对应的星期 return $weekArr[$numberWk]; }取得指定日期前後相同時間天數的時間範圍
/** * 获取指定日期前后相同时间天数的范围时间 * @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; }
#取得兩個日期之間相差的天數
/** * 获取两个日期之间相差的天数 * @param string $day1 第一个日期,格式为Y-m-d * @param string $day2 第二个日期,格式为Y-m-d * @return integer */ public static function getDiffBetweenTwoDays($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,取得結束的日期
/** * 根据日期和相差的天数获取结束的天数 * @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
/** * 判断两个时间是否同一天 * @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
/** * 转换秒钟为分钟 * @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 $time; }
取得毫秒數
/** * 获取时间的毫秒数 * @return float */ public static function millisecond() { list($msec, $sec) = explode(' ', microtime()); return (float)sprintf('%.0f', (floatval($msec) + floatval($sec)) * 1000); }
