[{
"name": "北京",
"city": [{
"name": "北京",
"area": ["东城区", "西城区", "崇文区", "宣武区", "朝阳区", "丰台区", "石景山区", "海淀区", "门头沟区", "房山区", "通州区", "顺义区", "昌平区", "大兴区", "平谷区", "怀柔区", "密云县", "延庆县"]
}]
}, {
"name": "天津",
"city": [{
"name": "天津",
"area": ["和平区", "河东区", "河西区", "南开区", "河北区", "红桥区", "塘沽区", "汉沽区", "大港区", "东丽区", "西青区", "津南区", "北辰区", "武清区", "宝坻区", "宁河县", "静海县", "蓟 县"]
}]
}]使用PHP的foreach进行循环输出：
$str = '[{"name":"北京","city":[{"name":"北京","area":["东城区","西城区","崇文区","宣武区","朝阳区","丰台区","石景山区","海淀区","门头沟区","房山区","通州区","顺义区","昌平区","大兴区","平谷区","怀柔区","密云县","延庆县"]}]},{"name":"天津","city":[{"name":"天津","area":["和平区","河东区","河西区","南开区","河北区","红桥区","塘沽区","汉沽区","大港区","东丽区","西青区","津南区","北辰区","武清区","宝坻区","宁河县","静海县","蓟 县"]}]}]';
$provinces = json_decode($str, true);
foreach($provinces as $province){
echo $province['name'], '';
foreach($province['city'] as $city){
echo '：', $city['name'], '';
echo '
';
foreach($city['area'] as $area){
echo '----', $area, '';
echo '
';
}
}
}
exit;输出结果：
