PHP在递归数组中移动重复项

Question

I building a translation form that is build using a array filled with the translation keys, to keys are however often duplicated. As the form is builded in group i want to move the duplicates to the $translatables['global'] Note that what you're seeing in the image below is already placed in $translatables['modules']['Module_{{ModuleName}}']

As you can see in the image below, some fields are duplicates. those needs to be moved. The duplicates can be placed accross multiple elements.

I edit for the duplicate message: It ain't, its a question to move those values not to filter them (and keep 1 remaining), they need to be placed under a global section.

Answer 1

I solved it myself

class Tools_Array
{
    public static function find_duplicates_recursive(&$array, $remove = false)
    {
        $duplicates = array();

        $valueCounts = array_count_values(self::array_values_recursive($array));
        foreach ($valueCounts as $key => $value) {
            if ($value > 1)
            {
                $duplicates[] = $key;
            }
        }

        if ($remove) {
            foreach ($duplicates as $duplicate)
            {
                $array = self::remove_values_recursive($array, $duplicate);
            }
        }

        return $duplicates;
    }

    public static function array_values_recursive($array)
    {
        $arr2 = array();
        foreach ($array as $key => $value)
        {
            if(is_array($value))
            {
                $arr2 = array_merge(array_values_recursive($value), $arr2);
            }else{
                $arr2[] = $value;
            }
        }

        return $arr2;
    }

    public static function remove_values_recursive($array, $needle)
    {
        foreach ($array as $key => $value)
        {
            if(is_array($value))
            {
                $array[$key] = self::remove_values_recursive($value, $needle);
            }else{
                if ($value == $needle)
                {
                    unset($array[$key]);
                }
            }
        }

        return $array;
    }
}

Then i can filter it with:

$duplicates = Tools_Array::find_duplicates_recursive($translatables, true);
$translatables['globaal'] = array_merge($translatables['globaal'], $duplicates);
