如何处理这段字符串，为数组赋值
如何处理这段字符串：
"BronzeList":[],"GoldList":["ATM054000"],"SilverList":["ATW099000"],"nation":"GER","nationName":"德国","rank":1,"rankTotal":1,"sortRank":1,"sortRankTotal":1,"totalBronze":8,"totalGold":8,"totalMedal":22,"totalSilver":6
来为数组赋值$array($key=>$value)，使用逗号分割字符串，每项使冒号前面的内容为数组的$key,冒号后面的内容为数组的$value。
赋值的数组结果例如：$array = ("BronzeList"=>null,"GoldList"=>"ATM054000","SilverList"=>"ATW099000","nation"=>"GER",,,,)

求大侠帮忙。

他不是 json 吗？

PHP code

$json='{"BronzeList":[],"GoldList":["ATM054000"],"SilverList":["ATW099000"],"nation":"GER","nationName":"德国","rank":1,"rankTotal":1,"sortRank":1,"sortRankTotal":1,"totalBronze":8,"totalGold":8,"totalMedal":22}';
print_r(json_decode($json,true));
