我什至不知道該用什么詞:)我有一個數(shù)組：array( 0 => array( 'protein' => 'proteiny', 'total_fat' => 'total faty', 'carbohydrates' => 'carbohydrates', 'food_energy' => 'food energy',...另一個數(shù)組：1 => array( 'protein' => 'grams', 'total_fat' => 'grams', 'carbohydrates' => 'grams', 'food_energy' => 'kcals',...我想在這個結(jié)構(gòu)中將它們組合成一個新數(shù)組：$newone = array( array('slug' => 'protein', 'name' => 'proteiny', 'format' => 'grams'), array('slug' => 'total_fat', 'name' => 'total faty', 'format' => 'grams'), array('slug' => 'carbohydrates', 'name' => 'carbohydrates', 'format' => 'grams'), array('slug' => 'food_energy', 'name' => 'food energy', 'format' => 'kcals'), ...有沒有辦法做到這一點？

您可以在具有范圍use($b)的數(shù)組上使用array_map( )來制作. 例子：$a$newone
$a = array('protein' => 'proteiny', 'total_fat' => 'total faty', 'carbohydrates' => 'carbohydrates', 'food_energy' => 'food energy');
$b = array('protein' => 'grams', 'total_fat' => 'grams', 'carbohydrates' => 'grams', 'food_energy' => 'kcals');
$newone = array_map(function($val, $slug) use ($b) {
return array('slug' => $slug, 'name' => $val, 'format' => $b[$slug]);
}, $a, array_keys($a));
print_r($newone);

foreach當$a第一個數(shù)組$b是第二個數(shù)組時，簡單循環(huán)如何：
foreach($a as $k => $e) {
$res[] = array('slug' => $k, 'name' => $e, 'format' => $b[$k]);
}
