A=[[0] =>[[time] => 2015-11-01,
[draw] => 900],
[1] =>[[time] => 2015-11-02,
[draw] => 1512],
[2] =>[[time] => 2015-11-05,
[draw] => 1600]];
B=[[0] =>[[time] => 2015-11-01,
[data] => 90],
[1] =>[[time] => 2015-11-03,
[data] => 152],
[2] =>[[time] => 2015-11-05,
[data] => 100]];
我要把AB数组合并成一个数组,按照[time]相同的合并在一起,达到这样一个效果:
C=[[0] =>[[time] => 2015-11-01,
[draw] => 900, [data] => 90],
[1] =>[[time] => 2015-11-02,
[draw] => 1512],
[2] =>[[time] => 2015-11-03,
[data] => 152],
[3] =>[[time] => 2015-11-05,
[draw] => 1300, [data] => 100]];
类似数据库的"full join", , 这个有办法实现吗?
如这样两个数组:
A=[[0] =>[[time] => 2015-11-01,
[draw] => 900],
[1] =>[[time] => 2015-11-02,
[draw] => 1512],
[2] =>[[time] => 2015-11-05,
[draw] => 1600]];
B=[[0] =>[[time] => 2015-11-01,
[data] => 90],
[1] =>[[time] => 2015-11-03,
[data] => 152],
[2] =>[[time] => 2015-11-05,
[data] => 100]];

function setKeyByTime($arr) {
$res = array();
foreach($arr as $item) {
$res[$item['time']] = $item;
}
return $res;
}
$C = array_merge_recursive( setKeyByTime($A), setKeyByTime($B) );
