我从 DB 获得了三个数组，一个是健康机构名称数组，另一个是交货数据，最后一个是交货数据中日期的日期数组。例如：

Array ( 
[0] => stdClass Object ( [health_inst_code] => 32HI083 [health_inst_name] => DHM)
[1] => stdClass Object ( [health_inst_code] => 32HI084 [health_inst_name] => THQHSB) 
[2] => stdClass Object ( [health_inst_code] => 32HI085 [health_inst_name] => CHCM) 
[3] => stdClass Object ( [health_inst_code] => 32HI086 [health_inst_name] => THQHV) 
[4] => stdClass Object ( [health_inst_code] => 32HI087 [health_inst_name] => GHK) 
)



Array (

 )



Array ( 
[0] => stdClass Object ( [delivery_date] => 2021-05-28 ) 
[1] => stdClass Object ( [delivery_date] => 2021-05-27 ) 
[2] => stdClass Object ( [delivery_date] => 2021-05-26 )
[3] => stdClass Object ( [delivery_date] => 2021-05-25 ) 
[4] => stdClass Object ( [delivery_date] => 2021-05-24 ) 
[5] => stdClass Object ( [delivery_date] => 2021-05-23 ) 
[6] => stdClass Object ( [delivery_date] => 2021-05-22 ) 
)

我想在 PHP 中将数组显示为二维数组，如下所示：

             | 2021-05-28 |  2021-05-27 |  2021-05-26|  2021-05-25 |  2021-05-24 |2021-05-23|2021-05-22 |
|            |            |             |            |             |             |          |           |
---------------------------------------------------------------------------------------------------------
|    DHM     |    8       |      -      |     7      |      7      |      6      |    4      |    10
|   THQHSB   |    -       |      0      |     4      |      2      |      3      |    4      |     2
|   CHCM     |    -       |      0      |     1      |      0      |      0      |    0      |     1
|   THQHV    |    -       |      1      |     0      |      1      |      0      |    1      |     0
|   GHK      |    -       |      3      |     1      |      2      |      5      |    0      |     1

我该怎么做？

要获得您想要的两个暗淡数组，我们只需要第二个数组。

<?php
// example code

$array2 = array ( 
"0" => (object) array ( "dd_id" => 620, "delivery_date" => "2021-05-28", "health_inst_name" => "DHM", "delivery_institution" => "32HI083", "total_delivery" => 8 ) ,

}

print_r($twodim);

这将为您提供以下输出，您可以轻松地将其操作到您在问题中说明的表格中：

【讨论】：

第一个!isset() 是不必要的。在 php.ini 中，父级别不需要在子级别之前声明。如果这项工作是如何获得数据的运行计数，我们已经在 Stack Overflow 上有重复的工作。
