$result = [ ['month'=>08,'price'=>218], ['month'=>12,'price'=>140],];
//先构造类似 ['01'=>0,'02'=>0 .... '12'=>0] 这种格式的数组 $fullMonth = []; for($i=1;$i<=12;$i++){ $fullMonth[str_pad($i,2,'0',STR_PAD_LEFT)] = 0; } // 遍历数组 对应月份有值就放到新建的数组里 $i = 0; foreach($fullMonth as $month=>$value){ foreach($result as $record){ if($month == $record['month']){ $fullMonth[$month] = $record['price']; } } $i++; } return '[' . implode(',',$fullMonth) . ']';
为什么不用json格式?
$result = [ ['month'=>08,'price'=>218], ['month'=>12,'price'=>140],];echo json_encode($result); // [{"month":0,"price":218},{"month":12,"price":140}]
New Document 08,'price'=>218], ['month'=>12,'price'=>140], ]; ?>
$r = array_fill(0, 12, null);$result = [ ['month'=> '08', 'price'=> 218], ['month'=> '12', 'price'=> 140],];foreach($result as $v) { $r[$v['month'] - 1] = $v['price'];}echo json_encode($r);
[null,null,null,null,null,null,null,218,null,null,null,140]
进一步询问
已知
$res = [[y=>'2014-12-03','item'=>263],[y=>'2014-12-04','item'=>168]];
[ {y: '2014-12-01', item: null}, {y: '2014-12-02', item: null}, {y: '2014-12-03', item: 263}, {y: '2014-12-04', item: 168}, {y: '2014-12-05', item: null}, ..... {y: '2014-12-31', item1:null},]
y加上引?,??才不?有notice
'2014-12-03','item'=>263],['y'=>'2014-12-04','item'=>168]];echo json_encode($res, JSON_PRETTY_PRINT);?>
