脚本宝典收集整理的这篇文章主要介绍了php – 内连接数组结果，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
Array
(
[0] => Array
(
[foo1] => Apple
[foo2] => Banana
[foo3] => Carrots
[foo4] => Deer
[foo5] => Feather
[foo6] => GraPEs
)
[1] => Array
(
[foo1] => Apple
[foo2] => Banana
[foo3] => Carrots
[foo4] => Deer
[foo5] => Feather
[foo6] => Heater
)
[2] => Array
(
[foo1] => Apple
[foo2] => Banana
[foo3] => Carrots
[foo4] => Deer
[foo5] => Feather
[foo6] => Quail Eggs
)
)
查询：
SELECT tpp.page_master_PRoperties_style AS foo1,tpp.page_master_properties_bg AS foo2,tpp.page_master_properties_data AS foo3,tpp.page_properties_style AS foo4,tpp.page_properties_bg AS foo5,tpp.page_properties_data AS foo6,tobj.objects_script AS foo6 From templates t INNER JOIN category tc ON t.category_id = tc.category_id INNER JOIN page_properties tpp ON t.templates_id = tpp.templates_id INNER JOIN objects tobj ON t.templates_id = tobj.templates_id WHERE t.templates_id = ?
哪里？ = 1
这可能是因为Table对象有多个templates_id条目：
+--------------+----------------+-----------------+ | objects_id | templates_id | objects_script | +--------------+----------------+-----------------+ | 1 | 1 | Grapes | | 2 | 1 | Heater | | 3 | 1 | Quail Eggs | | 4 | 2 | Milk | | 5 | 3 | Lemon | +--------------+----------------+-----------------+
我想知道是否有任何内置的MysqL函数可以将foo6组合成一个奇异的数组,例如实现这样的结果：
Array
(
[foo1] => Apple
[foo2] => Banana
[foo3] => Carrots
[foo4] => Deer
[foo5] => Feather
[foo6] => Array
(
[0] => Grapes
[1] => Heater
[2] => Quail Eggs
)
)
SELECT tpp.page_master_properties_style AS foo1,group_concat(tpp.page_properties_data) AS foo6,tobj.objects_script AS foo6 From templates t INNER JOIN category tc ON t.category_id = tc.category_id INNER JOIN page_properties tpp ON t.templates_id = tpp.templates_id INNER JOIN objects tobj ON t.templates_id = tobj.templates_id WHERE t.templates_id = ? group by tpp.page_master_properties_style AS foo1,tpp.page_properties_bg AS foo5
这会将tpp.page_properties_data中的所有行组合到唯一的数据行中并用逗号分隔 – 当您循环遍历数据集时,可以轻松地将explode分成数组.
以上是脚本宝典为你收集整理的php – 内连接数组结果全部内容，希望文章能够帮你解决php – 内连接数组结果所遇到的问题。
