Php 将mySQL结果构造为多维数组

下面的代码从mySQL连接中获取一个包含一系列行的数组，并将它们重新构造为多维数组

 foreach($content as $cont){

    if(!$pagecontent){
        $pagecontent = $cont;
        $pagecontent['theme'] = array();
    }
    $themearray = array(
        'themeID' => $cont['themeID'],
        'theme_type' => $cont['theme_type'],
        'theme_file' => $cont['theme_file'],
        'theme_default' => $cont['theme_default'],
        'theme_title' => $cont['theme_title'],
        $cont['meta_field'] => $cont['meta_value']
    );

    array_push($pagecontent['theme'], $themearray);

}

下面是打印的输出阵列

Array
(
    [contentID] => 9
    [type] => operations
    [title] => CTK Partners
    [parent] => 8
    [theme] => Array
    (
        [0] => Array
            (
                [themeID] => 2
                [theme_type] => general
                [theme_file] => logo
                [theme_default] => 1
                [theme_title] => CTT Group
                [src] => uploads/img/clogo.png
            )

        [1] => Array
            (
                [themeID] => 2
                [theme_type] => general
                [theme_file] => logo
                [theme_default] => 1
                [theme_title] => CTT Group
                [title] => CTT Industries
            )

        [2] => Array
            (
                [themeID] => 5
                [theme_type] => general
                [theme_file] => logo
                [theme_default] => 0
                [theme_title] => CTT Logo 2
                [src] => uploads/img/cttlogo2.png
            )

        [3] => Array
            (
                [themeID] => 5
                [theme_type] => general
                [theme_file] => logo
                [theme_default] => 0
                [theme_title] => CTT Logo 2
                [title] => CTF Associates
            )

    )

)

问题是，我想按ID号列出主题数组，以便重复写入的字段只插入尚未定义的字段

我期待的结果是：

Array
    (
        [contentID] => 9
        [type] => operations
        [title] => CTK Partners
        [parent] => 8
        [theme] => Array
        (
            [themeID2] => Array
                (
                    [themeID] => 2
                    [theme_type] => general
                    [theme_file] => logo
                    [theme_default] => 1
                    [theme_title] => CTT Group
                    [src] => uploads/img/clogo.png
                    [title] => CTT Industries
                )

            [themeID5] => Array
                (
                    [themeID] => 5
                    [theme_type] => general
                    [theme_file] => logo
                    [theme_default] => 0
                    [theme_title] => CTT Logo 2
                    [src] => uploads/img/cttlogo2.png
                    [title] => CTF Associates
                )

        )

)

如何实现这一点？

为

$pagecontent['theme']

中的每一行指定一个键，如中所示

 $pagecontent['theme']["themeID{$cont['themeID']}"] = $themearray;

代替

数组\u push

行。

Dan的回答是正确的，但没有考虑到循环可能需要添加到主题数组而不覆盖它。他的代码的这种改编考虑到了这一点

if(!$pagecontent['theme']["themeID{$cont['themeID']}"]){
        $pagecontent['theme']["themeID{$cont['themeID']}"] = $themearray;
    }
    else {
        $pagecontent['theme']["themeID{$cont['themeID']}"][$cont['meta_field']] = $cont['meta_value'];
    }

很好。但它没有考虑到可能需要添加一个额外的字段。我修改了您的代码，因此它也可以用于此目的，因此获得1票。我的答案是下面使用您的代码。这很正常，但如果你发现问题，一定要告诉我。谢谢
