PHP 日期格式化示例代碼:
/** * 格式化時間 * $type:類型 * $strDate:需要處理的時間字符串 * * 年份 Y:四位年份 y:兩位年份 * 月份 m: 兩位數字月份 n: 一位數字月份 M:英文月 * 日期 d:兩位數字日期 j:一位數字日期 D:英文日期 * 時:H 、分:i 、秒:s **/ public function GetFormatDate($type = 1,$strDate=''){ $time = time(); if(isset($strDate) && !empty($strDate)){ $time = strtotime($strDate); } switch($type){ case 1: return date("H:i",$time); case 2: return date("m月d日 H:i",$time); case 3: return date("m/d H:i",$time); case 4: return date("Y年m月d日 H:i",$time); case 5: return date("Y/m/d H:i",$time); case 6: return date("Y年m月d日 H:i:s",$time); case 7: return date("Y-m-d H:i:s",$time); case 8: return date("Y/m/d H:i:s",$time); default: return $strDate; } }
日期計算示例代碼:
/** * 時間加減處理 * $strDate:需要處理的時間字符串 * $days: 加減天數 **/ public function ChangeDate($strDate,$days){ $time = time(); if(isset($strDate) && !empty($strDate)){ $time = strtotime($strDate); } return date('Y-m-d H:i:s',strtotime("$days day",$time)); }
獲取當前周、月頭尾日期示例代碼:
/** * 獲取當前周、月的頭尾日期 * * $dateArr['W1']:周一 * $dateArr['W7']:周末 * $dateArr['M1']:月頭 * $dateArr['M2']:月尾 **/ public function GetCurrentDateInfo(){ $dayTimes = 24*60*60; $dateArr = [];$temp = ''; $weekIndex = (int)date('w'); switch($weekIndex){ case 0: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('+1 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+7 day')); break; case 1: $dateArr['W1'] = date('Y-m-d 00:00:00'); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+6 day')); break; case 2: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('-1 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+5 day')); break; case 3: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('-2 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+4 day')); break; case 4: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('-3 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+3 day')); break; case 5: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('-4 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+2 day')); break; case 6: $dateArr['W1'] = date('Y-m-d 00:00:00',strtotime('-5 day')); $dateArr['W7'] = date('Y-m-d 23:59:59',strtotime('+1 day')); break; } //1-12:一月 至 十二月 $monthIndex = (int)date('m'); switch($monthIndex){ case 1: $temp = date('Y-02-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 2: $temp = date('Y-03-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 3: $temp = date('Y-04-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 4: $temp = date('Y-05-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 5: $temp = date('Y-06-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 6: $temp = date('Y-07-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 7: $temp = date('Y-08-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 8: $temp = date('Y-09-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 9: $temp = date('Y-10-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 10: $temp = date('Y-11-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 11: $temp = date('Y-12-01 00:00:00'); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; case 12: $temp = date((date('Y')+1)."-01-01 00:00:00"); $dateArr['M1'] = date('Y-m-01 00:00:00'); $dateArr['M2'] = date('Y-m-d 23:59:59',strtotime($temp)-$dayTimes); break; } return $dateArr; }
