foreach循环导致无效的json [英] invalid json resulted by foreach loop

问题描述

说我想获取某物的值并将其存储在arr中以生成json:

says I want to get a value of something and store in into an arr to produce json :

foreach($item as $items){
   $items = $someting->name;

$arr = array(
   'itemName'=>$items
);

    echo json_encode($arr);

};

结果

{'itemName':'shoe}{'itemName':'toy}{'itemName':'ball}

它在后面缺少分号.

推荐答案

在大多数情况下，json_encode仅应调用一次.继续在php数组中添加所有要转换为JSON的内容，然后调用json_encode

In most cases json_encode should be called once only. Keep adding all you want to convert to JSON in a php array, then call json_encode

$json = array('items' => array());
foreach ($items as $item) {
    $json['items'][] = array(
       'itemName' => $item->name
    );
};

echo json_encode($json);

您还可以为所有$ items数组调用json_encode，而无需执行循环

You could also call json_encode for all your $items array without doing a loop

json_encode($items)
