如何从数组中删除此＆＃34; 0＆＃34;：{

Question

$test = array('hola'=>'mundo','salami'=>'frito');
$data = array(
    'gift_promoted' => '',
    'questions' => array(
        0 => array(
            'extra' => array()
        )
    ),
    'quiz' => array(
        'extra' => array(),
        $test
    )
);

print json_encode($data);

实际结果：

{"gift_promoted":"","questions":[{"extra":[]}],"quiz":{"extra":[],"0":{"hola":"mundo","salami":"frito"}}}

我需要这个：

{"gift_promoted":"","questions":[{"extra":[]}],"quiz":{"extra":[],"hola":"mundo","salami":"frito"}}

Answer 1

有点脏：

$test = array('hola'=>'mundo','salami'=>'frito'); $data = array(
     'gift_promoted' => '',
     'questions' => array(
         0 => array(
             'extra' => array()
         )
     ),
     'quiz' => array(
         'extra' => array(),
         //$test --> remove this.
     ) );

 foreach($test as $key => $value) {     $data['quiz'][$key]=$value; }

 print json_encode($data);
