向内部数组添加键值对

adding a key-value pair to inner array

本文关键字：键值对添加数组内部 | 更新日期: 2023-09-27

 $a = array (
     [2011-07-09] => array(['new'] => 12),
     [2011-07-10] => array(['new'] => 15)
 );

现在我想在内部数组中添加另一个键值对，这样输出就像

 $a = array (
     [2011-07-09] => array(['new'] => 12, ['recurring'] => 52),
     [2011-07-10] => array(['new'] => 15, ['recurring'] => 80)
 );

$a['2011-07-09']['recurring'] = 52;
$a['2011-07-10']['recurring'] = 80;

根据您计划如何实现recurring键，可以这样做:

$a['2011-07-09']['recurring'] = 52;
$a['2011-07-10']['recurring'] = 80;
