Question

我有一个想要合并（合并）的关联数组。实际代码是：

Array
(
    [0] => Array
        (
            [Id_Usager] => 291
            [etat_lundi] => livree
            [Date_lundi] => 2011-12-26
            [etat_mardi] => livree
            [Date_mardi] => 2011-12-27
            [etat_mercredi] => livree
            [Date_mercredi] => 2011-12-28
            [etat_jeudi] => livree
            [Date_jeudi] => 2011-12-29
            [etat_vendredi] => livree
            [Date_vendredi] => 2011-12-30
            [etat_samedi] => livree
            [Date_samedi] => 2011-12-31
            [etat_dimanche] => livree
            [Date_dimanche] => 2012-01-01
        )

    [1] => Array
        (
            [Id_Usager] => 291
            [etat_lundi] => livree
            [Date_lundi] => 2012-01-02
            [etat_mardi] => livree
            [Date_mardi] => 2012-01-03
            [etat_mercredi] => en_cours
            [Date_mercredi] => 2012-01-04
            [etat_jeudi] => en_cours
            [Date_jeudi] => 2012-01-05
            [etat_vendredi] => en_cours
            [Date_vendredi] => 2012-01-06
            [etat_samedi] => en_cours
            [Date_samedi] => 2012-01-07
            [etat_dimanche] => en_cours
            [Date_dimanche] => 2012-01-08
        )

)

我最终想要的是：

取消设置第一个元素（Id_Usager）
将子阵列合并为一个
通过将etat值（[etat_lundi] => livree）移动为Date键（[Date_lundi] => 2012-01-02）

我想要的结果是：

Array(
    [0] => Array(
        [livree] => 2011-12-26
        [livree] => 2011-12-27
        [livree] => 2011-12-28
        [livree] => 2011-12-29
        [livree] => 2011-12-30
        [livree] => 2011-12-31
        [livree] => 2012-01-01
        [livree] => 2012-01-02
        [livree] => 2012-01-03
        [en_cours] => 2012-01-04
        [en_cours] => 2012-01-05
        [en_cours] => 2012-01-06
        [en_cours] => 2012-01-07
        [en_cours] => 2012-01-08
    )
)

我该怎么做？

Answer 1

array_merge()

在你的情况下：

$new_data = array_merge($data[0], $data[1]);

请注意，根据文档：

如果输入数组具有相同的字符串键，则后面的值该密钥将覆盖前一个密钥。

从您的示例数据中可以看出，您有重复的键名称（ Ben D 指出这是不可能的）。但是，它们包含相同的值。所以你应该没问题。
