php处理json数据的问题

Question

phpjson

Answer 1

你返回的json有问题，少了两个{{"status":0,"total":4,"data":"[{\"Gid\":\"123\",\"CardID\":\"15301\",\"Title\":\"标题一\"},\"Gid\":\"456\",\"CardID\":\"15333\",\"Title\":\"标题二\"},\"Gid\":\"789\",\"CardID\":\"15405\",\"Title\":\"标题三\"}]"}
修改为：
{"status":0,"total":4,"data":"[{\"Gid\":\"123\",\"CardID\":\"15301\",\"Title\":\"标题一\"},{\"Gid\":\"456\",\"CardID\":\"15333\",\"Title\":\"标题二\"},{\"Gid\":\"789\",\"CardID\":\"15405\",\"Title\":\"标题三\"}]"}循环输出：echo '<meta http-equiv="content-type" content="text/html; charset=utf-8">';
$response = '{"status":0,"total":4,"data":"[{\"Gid\":\"123\",\"CardID\":\"15301\",\"Title\":\"标题一\"},{\"Gid\":\"456\",\"CardID\":\"15333\",\"Title\":\"标题二\"},{\"Gid\":\"789\",\"CardID\":\"15405\",\"Title\":\"标题三\"}]"}';
$ret = json_decode($response, true);
$data = json_decode($ret['data'], true);foreach($data as $val){
    echo 'Gid:'.$val['Gid'].'<br>';
    echo 'CardID:'.$val['CardID'].'<br>';
    echo 'Title:'.$val['Title'].'<br><br>';
}
Gid:123
CardID:15301
Title:标题一Gid:456
CardID:15333
Title:标题二Gid:789
CardID:15405
Title:标题三
