修改数组合并

Question

希望我能解释一下，以便于理解。我很挣扎，所以我来这里希望能得到一些帮助:)

我正在组合/合并几个表。它似乎工作得很好，但您会注意到下面的代码行。

$records = array_merge($records, $records3);

我需要对其进行修改，使其包含“来源”。

例如：

{
    "tags": [
        {
            "id": "1",
            "name": "video",
            "cssanimate": "flipInY",
             source:{
                "mp4": "1.mp4",
                "ogg": ""
            }
        }
    ]
},

这就是它现在的显示方式。这是错误的！

{
    "tags": [
        {
            "id": "1",
            "name": "video",
            "cssanimate": "flipInY",
            "mp4": "1.mp4",
            "ogg": ""
        }
    ]
},

这是我的代码：

$result = $mysqli->query("SELECT id, username, volume, name, content, image, cssanimate, group_name FROM table_1 ORDER BY id ");
$result2 = $mysqli->query("SELECT id, username, volume, name, content, image, cssanimate, group_name FROM table_2 ORDER BY position");
$result3 = $mysqli->query("SELECT id, name, cssanimate, mp4, ogg FROM table_3 ORDER BY id ");


$records2 = array();
while ($row2 = $result2->fetch_assoc()) {
    $records2[] = array('tags' => array($row2));
}

$records3 = array();
while ($row3 = $result3->fetch_assoc()) {
    $records3[] = array('tags' => array($row3));
}

// Place "table_2" and "table_3" in every 10th position
$counter = 0;
while ($row = $result->fetch_assoc()) {

    $counter++;
    if(($counter % 10 == 0) || $counter==1 ) {
        $records = array_merge($records, $records2);
        $records = array_merge($records, $records3);
    }
    $records[] = array('tags' => array($row));
}


// Make is pretty
$json = json_encode($records, JSON_PRETTY_PRINT);


......

感谢任何帮助！

尝试为此使用内置函数会发疯。让它完全按照你的意愿去做太复杂了；我建议手动构建该数组：

$result3 = $mysqli->query("SELECT id, name, cssanimate FROM table_3 ORDER BY id ");
$result4 = $mysqli->query("SELECT mp4, ogg FROM table_3 ORDER BY id ");

...

$records4 = array();
while ($row4 = $result4->fetch_assoc()) {
    $records4[] = array('tags' => array('source' => array($row4)));
}

$merged = array_merge_recursive($records3, $records4);
