本文实例讲述了PHP实现数组根据某个字段进行水平合并,横向合并。分享给大家供大家参考,具体如下:
PHP数组水平合并,横向合并,两条数据合并成一行
需求
将两个素组中日期相同的合并成一行
数组a
Array
(
[0] = Array
(
[date] = 2019-04-02
[today_pay_money] = 168.00
[today_pay_num] = 1
[yesterday_pay_money] = 999.00
[yesterday_pay_num] = 1
)
[1] = Array
(
[date] = 2019-04-09
[today_pay_money] = 0.01
[today_pay_num] = 1
[yesterday_pay_money] = 0.00
[yesterday_pay_num] = 0
)
[2] = Array
(
[date] = 2019-05-05
[today_pay_money] = 0.01
[today_pay_num] = 1
[yesterday_pay_money] = 2.00
[yesterday_pay_num] = 1
)
[3] = Array
(
[date] = 2019-05-11
[today_pay_money] = 0.00
[today_pay_num] = 0
[yesterday_pay_money] =
[yesterday_pay_num] = 1
)
)
数组B
Array
(
[0] = Array
(
[date] = 2019-05-07
[today_pay_money1] = 0
[today_pay_num1] = 0
[yesterday_pay_money1] = 0
[yesterday_pay_num1] = 0
)
[1] = Array
(
[date] = 2019-05-11
[today_pay_money1] = 0
[today_pay_num1] = 0
[yesterday_pay_money1] = 1
[yesterday_pay_num1] = 1
)
)
需要格式
Array
(
[2019-04-02] = Array
(
[date] = 2019-04-02
[today_pay_money] = 168.00
[today_pay_num] = 1
[yesterday_pay_money] = 999.00
[yesterday_pay_num] = 1
)
[2019-04-09] = Array
(
[date] = 2019-04-09
[today_pay_money] = 0.01
[today_pay_num] = 1
[yesterday_pay_money] = 0.00
[yesterday_pay_num] = 0
)
[2019-05-05] = Array
(
[date] = 2019-05-05
[today_pay_money] = 0.01
[today_pay_num] = 1
[yesterday_pay_money] = 2.00
[yesterday_pay_num] = 1
)
[2019-05-11] = Array
(
[date] = 2019-05-11
[today_pay_money] = 0.00
[today_pay_num] = 0
[yesterday_pay_money] =
[yesterday_pay_num] = 1
[today_pay_money1] = 0
[today_pay_num1] = 0
[yesterday_pay_money1] = 1
[yesterday_pay_num1] = 1
)
[2019-05-07] = Array
(
[date] = 2019-05-07
[today_pay_money1] = 0
[today_pay_num1] = 0
[yesterday_pay_money1] = 0
[yesterday_pay_num1] = 0
)
)
代码实现
先将a,b数组合并,判断当前日期下是否空,空的话直接赋值,不空的话,将已有素组和当前数组合并
$total = array_merge($a,$b));
$res = array();
foreach ($total as $k = $v) {
if (empty($res[$v['date']]))
$res[$v['date']] = $v;
else
$res[$v['date']]= array_merge($res[$v['date']],$v);
}
