Php 从数组中合并json，然后重新创建数组

php arrays json

Php 从数组中合并json，然后重新创建数组,php,arrays,json,Php,Arrays,Json,我有一个数组，如下所示 Array ( [photo] => Array ( [0] => {"file_name":"Penguins.jpg", "content_type": "image/jpeg", "tmp_path": "/var/www/servergreek.com/public_html/www/imgscript/tmp/0048699176"} [1] => {"file_name"

我有一个数组，如下所示

    [photo] => Array
        (

这里有一个解决方案，它使用解码的JSON对象构建一个映射，通过其文件名值进行键控，然后应用于将该映射中的对象转换回JSON字符串
中间层将关联数组转换为索引数组：
$data['photo'] = array_map('json_encode', array_values(array_reduce($data['photo'], 
    function($dict, $json) {
        $obj = json_decode($json, true);
        $key = $obj['file_name'];
        if (!isset($dict[$key])) $dict[$key] = [];
        $dict[$key] += $obj; // merging arrays with plus operator
        return $dict;
    }, []))
);

此解决方案不需要两个相关的JSON字符串是连续的。如果数组的顺序是任意的，它就可以工作。如果有两个以上的JSON字符串具有相同的文件名
属性，并将这些额外的JSON字符串中的任何其他属性连接起来，那么它也可以工作
查看它的运行情况。
