关于PHP循环读取json数据的方法

推荐：《PHP视频教程》

现有json数据如下：

[{"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;
