我有一個來自表示表單的 json 的數組。我必須將所有 [components] 收集到一個新數組中我解決了對 foreach 的認真處理，并在每個循環中使用了邏輯：如果不存在數組“組件”-> 檢查是否是類型列如果是，檢查是否存在“組件”并保存在新數組中如果不保存在新數組中如果再次存在，則對 3 或 4 個子級別應用與第 1 點相同的條件。這是我需要的最后一個數組Array ( [0] => Array ( [key] => number1 [type] => number [input] => 1 [label] => Test Number Field ) [1] => Array ( [key] => testRadioFiled [type] => radio [label] => Test Radio Filed [values] => Array ( [0] => Array ( [label] => First [value] => first [shortcut] => ) ) ) ...... [2] => Array ( [key] => testSelectMultipleField [data] => Array ( [values] => Array ( [0] => Array ( [label] => First [value] => first ) [1] => Array ( [label] => Second [value] => second )

如果我理解你正確遞歸可以幫助：
function extractComponents($arrayWithComponents)
{
$components = [];
if (!isset($arrayWithComponents['components']) || !is_array($arrayWithComponents['components'])) {
return $components;
}
foreach ($arrayWithComponents['components'] as $component) {
if (isset($component['columns'])) {
foreach ($component['columns'] as $column) {
$components = array_merge($components, extractComponents($column));
}
} else {
$components = array_merge($components, extractComponents($component));
unset($component['components']);
$components[] = $component;
}
}
return $components;
}
var_dump(extractComponents($data));
