我有一個(gè)數(shù)組，但我不知道如何將其更改為我需要的結(jié)構(gòu)：我的數(shù)組：array ( "1536" => "12", "1695" => "Korea", "1904" => "10/7", "1905" => "", "1906" => null, "1907" => "1.1", "1906.1" => "H1", "1906.2" => "H35", "1905.1" => "15")我需要將此數(shù)組轉(zhuǎn)換為這種形式（刪除十分之一的數(shù)字，并將相同數(shù)字的值粘貼到數(shù)組中）：array ( "1536" => "12", "1695" => "Korea", "1904" => "10/7", "1905" => array("", "15"), "1906" => array(null, "H1", "H35"), "1907" => "1.1")

使用array_walk()對(duì)數(shù)組進(jìn)行迭代。在迭代檢查天氣的每個(gè)循環(huán)中，鍵已經(jīng)存在于$res數(shù)組中。如果存在，則創(chuàng)建與舊值合并的數(shù)組并分配給相同的鍵。如果不存在鍵，則將 分配$val給$res數(shù)組。
$data = array("1536" => "12","1695" => "Korea","1904" => "10/7","1905" => "", "1906" => null,"1907" => "1.1","1906.1" => "H1","1906.2" => "H35","1905.1" => "15");
$res = array();
array_walk($data, function($val, $key) use(&$res) {
$key = intval($key);
if (array_key_exists($key, $res)) {
$res[$key] = is_array($res[$key]) ? array_merge($res[$key], [$val]) : array_merge([$res[$key]], [$val]);
} else {
$res[$key] = $val;
}
});
print_r($res);
