我需要像这样创建数组：

Array('firstkey' => Array('secondkey' => Array('nkey' => ...)))

从这里：

firstkey.secondkey.nkey.(...) 推荐答案$yourString = 'firstkey.secondkey.nkey'; // split the string into pieces $pieces = explode('.', $yourString); $result = array(); // $current is a reference to the array in which new elements should be added $current = &$result; foreach($pieces as $key){ // add an empty array to the current array $current[ $key ] = array(); // descend into the new array $current = &$current[ $key ]; } //$result contains the array you want
