PHPExcel导出动态合并单元格-CI

先上效果图

代码有点蠢 大神勿喷

这样的数据结构拿到后来计算合成单元格的跨度 比如: A1:A30 B1:E1 这种

$arr = [
    ['year'=>'2018','month'=>'08','day'=>'10'],
    ['year'=>'2018','month'=>'08','day'=>'11'],
    ['year'=>'2018','month'=>'09','day'=>'12'],
    ['year'=>'2018','month'=>'09','day'=>'13']
];

//通过上面的代码拿到 

$a = ['A2:A5']; $b = ['B2:B3','B4:B5'];

//数组排序一定是以上这样有序的,不是下面这种无须的

$arr = [
    ['year'=>'2018','month'=>'08','day'=>'10'], //08
    ['year'=>'2018','month'=>'09','day'=>'11'], //09
    ['year'=>'2018','month'=>'08','day'=>'12'], //08
    ['year'=>'2018','month'=>'09','day'=>'13'] //09
];

附上全部代码 CI框架写的

 1         $arr = [
 2             ['year'=>'2018','month'=>'08','day'=>'10'],
 3             ['year'=>'2018','month'=>'08','day'=>'11'],
 4             ['year'=>'2018','month'=>'09','day'=>'12'],
 5             ['year'=>'2018','month'=>'09','day'=>'13']
 6         ];
 7         $A = [];
 8         $year= $arr[0]['year'];
 9         $s = 2;
10         $e = 1;
11         $B = [];
12         $month= $arr[0]['month'];
13         $s1 = 2;
14         $e1 = 1;
15         foreach ($arr  as $k=> $v){
16             if($v['year'] !=$year){
17                 $A[]="A".$s.":A".$e."";
18                 $e++;
19                 $year= $v['year'];
20                 $s = $e;
21             }else{
22                 $e++;
23                 if(count($arr)==($k+1)){
24                     $A[]="A".$s.":A".$e."";
25                 }
26             }
27             if($v['month'] !=$month){
28                 $B[]="B".$s1.":B".$e1."";
29                 $e1++;
30                 $month = $v['month'];
31                 $s1 = $e1;
32             }else{
33                 $e1++;
