Use PHP's foreach for loop output:

$str = &#39;[{"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"]}]}]&#39;;
$provinces = json_decode($str, true);
foreach($provinces as $province){
    echo $province[&#39;name&#39;], &#39;&#39;;
    foreach($province[&#39;city&#39;] as $city){
        echo &#39;：&#39;, $city[&#39;name&#39;], &#39;&#39;;
		echo &#39;<br>&#39;;
        foreach($city[&#39;area&#39;] as $area){
            echo &#39;----&#39;, $area, &#39;&#39;;
			echo &#39;<br>&#39;;
