将多维数组与另一个具有条件的数组组合

以下解决方案以获得您想要的结果：

$languages = Array(
    'english' => Array(),
    'germany' => Array(),
    'russia' => Array()
);
$data = Array(
    'line0' => 'Some test',
    'english0' => 'English test',
    'germany0' => 'Dutch test',
    'russia0' => 'Russian test',
    'line1' => 'Some more test',
    'english1' => 'English some more test',
    'germany1' => 'Dutch some more test',
    'russia1' => 'Russian some more test',
);
$new_array = array();
foreach ($languages as $k => $v) {
    foreach ($data as $key => $value) {
        if (strpos($key, 'line') !== false || strpos($key, $k) !== false)
            $new_array[$k][$key] = $value;
    }
}
print_r($new_array);

输出：

Array
(
    [english] => Array
        (
            [line0] => Some test
            [english0] => English test
            [line1] => Some more test
            [english1] => English some more test
        )
    [germany] => Array
        (
            [line0] => Some test
            [germany0] => Dutch test
            [line1] => Some more test
            [germany1] => Dutch some more test
        )
    [russia] => Array
        (
            [line0] => Some test
            [russia0] => Russian test
            [line1] => Some more test
            [russia1] => Russian some more test
        )
)

但正如评论中所建议的，您应该创建更好的格式。例如，请参阅以下示例：

$new_array = array();
foreach ($languages as $k => $v) {
    foreach ($data as $key => $value) {
        $textarr = str_split($key, strlen($key) - 1);
//        print_r($textarr);
        if (strpos($key, 'line') !== false || strpos($key, $k) !== false)
        $new_array[$k][$textarr[0]][$textarr[1]] = $value;
    }
}
print_r($new_array);

输出：

Array
(
    [english] => Array
        (
            [line] => Array
                (
                    [0] => Some test
                    [1] => Some more test
                )
            [english] => Array
                (
                    [0] => English test
                    [1] => English some more test
                )
        )
    [germany] => Array
        (
            [line] => Array
                (
                    [0] => Some test
                    [1] => Some more test
                )
            [germany] => Array
                (
                    [0] => Dutch test
                    [1] => Dutch some more test
                )
        )
    [russia] => Array
        (
            [line] => Array
                (
                    [0] => Some test
                    [1] => Some more test
                )
            [russia] => Array
                (
                    [0] => Russian test
                    [1] => Russian some more test
                )
        )
)

希望这对你有帮助。

只是为了尝试。有关正确方法，请参阅契丹的答案

$newArray = array();
$finalArray = array();
$thirdArray = array('line','english','germany','russia'); // for formatting 2nd array
//$data is secondArray
$countData = count($data);
for($i=0;$i<$countData/4;$i++)
{
    foreach ($thirdArray as $key => $value) {
        $newArray[$i][$value.$i] =$data[$value.$i]; //formatting array
        }
}
foreach($newArray as $key=>$val)
{
    foreach($languages as $k=>$v){
            $finalArray[$k][line.$key] = $newArray[$key][line.$key];
            $finalArray[$k][$k.$key] = $newArray[$key][$k.$key];
    }
}

print_r($finalArray); // outputs desired results

假设：（键的增量为 1）来自$data数组。如果不是，此代码将给出未定义索引的错误。

$languageReference ：用作$languages参考，因为我不想将结果保存在同一个数组中，但如果需要，可以。

$reference ：将$data数组的引用保存为end()函数会将内部指针移动到数组的末尾，因此不想处理原始数组。

$languageReference = $languages;
$reference = $data;
end($reference);
$lastKey = key($reference);
$count = (int) $lastKey[strlen($lastKey) - 1];
foreach ($languageReference as $lang => $langData) {
    for ($index = 0; $index <= $count; $index++) {
        $languageReference[$lang]['line' . $index] = $data['line' . $count];
        $languageReference[$lang][$lang . $index] = $data[$lang . $count];
    }
}
echo "<pre>";
var_dump($languageReference);

输出：

array(3) {
  ["english"]=>
  array(4) {
    ["line0"]=>
    string(14) "Some more text"
    ["english0"]=>
    string(22) "English some more text"
    ["line1"]=>
    string(14) "Some more text"
    ["english1"]=>
    string(22) "English some more text"
  }

    ["line0"]=>
    string(14) "Some more text"
    ["germany0"]=>

    ["line1"]=>
    string(14) "Some more text"
    ["germany1"]=>
    string(20) "Dutch some more text"
  }
  ["russia"]=>
  array(4) {
    ["line0"]=>
    string(14) "Some more text"
    ["russia0"]=>
    string(22) "Russian some more text"
    ["line1"]=>
    string(14) "Some more text"
    ["russia1"]=>
    string(22) "Russian some more text"
  }
}
