PHP實現(xiàn)兩種排課方式

第PHP實現(xiàn)兩種排課方式兩種排課方式：

固定每周的固定時間上課（例：共上20節(jié)，每周六、周日早上8點-10點上課。假如今天周六凌晨1點，那么排課也需要從今天開始）總共上幾個周，每周上課時間比較個性化（例：共上三周，第一周周一周二早上8點-10點上課；第二周周三周四下午8點-10點上課；第三周周日中午11點-12點上課。）

第一種排課比較好實現(xiàn)，簡要代碼如下：

*生成日期列表

*@paramint$startDate開始日期時間戳格式

*@paramarray$timeList課時計劃列表

"start_at":"09:09",//開課時間

"end_at":"10:09",//結(jié)束時間

"week_at":1//周幾

"start_at":"12:09",//開課時間

"end_at":"13:09",//結(jié)束時間

"week_at":1//周幾

"start_at":"09:09",

"end_at":"10:09",

"week_at":5

*@paramint$amount課時計劃數(shù)量

*@paramint$skipHoliday跳過節(jié)假日

*@returnarray

publicfunctiongenerateDateList($startDate,$timeList,$amount,$skipHoliday=0)

//計算開始日期是周幾

$startDateWeek=intval(date('N',$startDate));

//規(guī)范化課時數(shù)據(jù)week_at做key的三維數(shù)組

foreach($timeListas$item){

$weekAt=$item['week_at'];

array_splice($item,0,0,$weekAt);

$key=array_shift($item);

$weeksTime[$key][]=$item;

$item=null;

unset($timeList);

if(empty($weeksTime)){

$this-addError('課時計劃數(shù)據(jù)為空');

returnfalse;

//設置跳過假期,獲取開始日期之后的節(jié)假日

if($skipHoliday){

$holiday=newHoliday();

$holidayData=$holiday-getHolidayList($startDate);

$holiday=null;

unset($holiday);

$nowTime=time();

$list=array();

for($weekStartTime=$startDate,$count=0;$count$amount;$weekStartTime+=86400*7){

//$currentWeek:周幾

foreach($weeksTimeas$currentWeek=$weekTime){

foreach($weekTimeas$time){

//算出對應的日期時間戳

$currentDateTime=$weekStartTime+(($startDateWeek=$currentWeek($currentWeek-$startDateWeek):(7-$startDateWeek+$currentWeek))*86400);

//對應的日期=開始時間+((開始時間對應周=數(shù)據(jù)對應的周幾？(數(shù)據(jù)對應的周幾-開始時間對應周)：（7-開始時間對應周+數(shù)據(jù)對應的周幾）)*86400)

//假期跳過排課

if($skipHoliday!empty($holidayData)){

$startUnix=$currentDateTime+$time['start_at']*3600;//開始時間

$endUnix=$currentDateTime+$time['end_at']*3600;//結(jié)束時間

$skip=false;

//選擇跳過節(jié)假日，且節(jié)假日與當前課程時間有重疊跳過

foreach($holidayDataas$item){

if(($item['start_at']$endUnix$item['end_at']$startUnix)||($item['start_at']===$startUnix$item['end_at']===$endUnix)){

$skip=true;

continue;

if($skip){

continue;

$currentDate=date('Y/m/d',$currentDateTime);

$startAt=strtotime($currentDate.$time['start_at'].':00');

$endAt=strtotime($currentDate.$time['end_at'].':00');

if($startAt$nowTime||$endAt$nowTime){

$this-addError('上課時間不能小于當前時間');

returnfalse;

$list[]=[

'date_at'=$currentDateTime,//日期

'week_at'=$currentWeek,//周幾

'start_at'=$startAt,

'end_at'=$endAt

$count++;

if($count=$amount){

break3;

$weeksTime=null;

unset($weeksTime);

return$list;

}

（例子，只用來展示數(shù)據(jù)結(jié)構(gòu)）假如總共5節(jié)課時，從6-25日開始排課，每周一、周六上課：

（例子，只用來展示數(shù)據(jù)結(jié)構(gòu)）排課結(jié)果為：

第二種排課方式稍微麻煩一點，簡要代碼如下：

*生成日期列表

*@paramint$startDate開始日期時間戳格式

*@paramarray$taskList任務列表

"start_at":"09:09",//開始上課時間

"end_at":"10:09",//結(jié)束時間

"week_at":1,//周幾

"week_number":1//第幾周

"start_at":"09:09",

"end_at":"10:09",

"week_at":2,

"week_number":1

"start_at":"09:09",

"end_at":"10:09",

"week_at":1,

"week_number":3

*@returnarray

publicfunctiongenerateDateList($startDate,$taskList)

//計算開始日期是周幾

$startDateWeek=intval(date('N',$startDate));

$list=[];

$nowTime=time();

$weekSign=$week=0;

foreach($taskListas$key=$task){

if($task['week_number']$weekSign$task['week_number']!=$week){

$weekSign=$task['week_number']-$week;

//計算每條數(shù)據(jù)對應的日期$key==0：確定第一周第一節(jié)課是在本周還是下一周

if($key==0||$task['week_number']==$week){

if($task['week']=$startDateWeek){

$task['date_at']=$startDate+

(($weekSign-1)*7+($task['week']-$startDateWeek))*86400;

}else{

$task['date_at']=$startDate+

(($weekSign)*7-($startDateWeek-$task['week']))*86400;

}else{

if($task['week']$startDateWeek){

$task['date_at']=$startDate+

(($weekSign)*7+($task['week']-$startDateWeek))*86400;

}else{

$task['date_at']=$startDate+

(($weekSign)*7-($startDateWeek-$task['week']))*86400;

$startDateWeek=intval(date('N',$task['date_at']));

$week=$task['week_number'];

$startDate=$task['date_at'];

$dateAt=date('Y/m/d',$task['date_at']);

$startAt=strtotime($dateAt.'00:00:00');

if($task['start_at']){

$startAt=strtotime($dateAt.$task['start_at'].':00');

$endAt=strtotime($dateAt.'23:59:59');

if($task['end_at']){

$endAt=strtotime($dateAt.$task['end_at'].':00');

if($startAt$nowTime||$endAt$nowTime){
