Question

我有一个Mysql查询：

SELECT 
    `pcm`.`ContactMechanismId` AS `ContactMechanismId`,
    `tel`.`AreaCode` AS `AreaCode`,
    `tel`.`PhoneNbr` AS `PhoneNbr`,
    `tel`.`Extension` AS `Extension`,
    `cmt`.`ContactMechanismTypeName` AS `ContactMechanismTypeName`,
    `c`.`DialingCode` AS `DialingCode`,
    `rt`.`RoleTypeName` AS `RoleTypeName`,
    `cmpt`.`ContactMechanismPurposeTypeName` AS `ContactMechanismPurposeTypeName`
FROM
    `PartyContactMechanisms` AS `pcm`
        INNER JOIN
    `Telephones` AS `tel` ON `pcm`.`ContactMechanismId` = `tel`.`ContactMechanismId`
        INNER JOIN
    `ContactMechanisms` AS `cm` ON `cm`.`ContactMechanismId` = `pcm`.`ContactMechanismId`
        INNER JOIN
    `ContactMechanismTypes` AS `cmt` ON `cmt`.`ContactMechanismTypeId` = `cm`.`ContactMechanismTypeId`
        INNER JOIN
    `Countries` AS `c` ON `tel`.`GeoId` = `c`.`GeoId`
        INNER JOIN
    `PartyContactMechanismPurposes` AS `pcmp` ON `pcm`.`ContactMechanismId` = `pcmp`.`ContactMechanismId`
        INNER JOIN
    `RoleTypes` AS `rt` ON `rt`.`RoleTypeId` = `pcm`.`RoleTypeId`
        INNER JOIN
    `ContactMechanismPurposeTypes` AS `cmpt` ON `pcmp`.`PurposeTypeId` = `cmpt`.`PurposeTypeId`

我从Mysql获得的结果是

    +--------------------+----------+----------+-----------+--------------------------+-------------+---------------+---------------------------------+
| ContactMechanismId | AreaCode | PhoneNbr | Extension | ContactMechanismTypeName | DialingCode | RoleTypeName  | ContactMechanismPurposeTypeName |

我需要将上面的结果转换为以下数组：

[
    [ContactMechanismId, AreaCode, PhoneNbr, Extension, ContactMechanismTypeName, DialingCode, RoleTypeName[], ContactMechanismPurposeTypeName[]
]

在数组RoleTypeName[]和ContactMechanismPurposeTypeName[]中，从mysql结果的相应列中获取某个ContactMechanismId的所有可能值。

我该怎么做？

Answer 1

您可以使用GROUP_CONCAT()

更改下面的选择语句

SELECT 
`pcm`.`ContactMechanismId` AS `ContactMechanismId`,
`tel`.`AreaCode` AS `AreaCode`,
`tel`.`PhoneNbr` AS `PhoneNbr`,
`tel`.`Extension` AS `Extension`,
`cmt`.`ContactMechanismTypeName` AS `ContactMechanismTypeName`,
`c`.`DialingCode` AS `DialingCode`,GROUP_CONCAT(
`rt`.`RoleTypeName`) AS `RoleTypeName`,GROUP_CONCAT(
`cmpt`.`ContactMechanismPurposeTypeName`) AS `ContactMechanismPurposeTypeName`

然后使用GROUP BY对数据进行分组，您将获得RoleTypeName和ContactMechanismPurposeTypeName作为逗号分隔值。您可以使用php循环迭代并使用explode()函数来形成数组

将mysql查询的结果转换为嵌套的php数组
