在PHP中使用Json解码数据

我需要用PHP解码这个Json，但我不知道如何解码。我看到了这个函数php.net/json，但它不知道如何解码这种类型的数据

{"c":[{"v":"0","e":"","n":"45","cc":"PSDB - PTB \/ PPS \/ DEM \/ PMN \/ PSDB \/ PT do B","nm":"JOSÉ SERRA","nv":"VICE: ÃNDIO DA COSTA"},{"v":"0","e":"","n":"13","cc":"PT - PRB \/ PDT \/ PT \/ PMDB \/ PTN \/ PSC \/ PR \/ PTC \/ PSB \/ PC do B","nm":"DILMA","nv":"VICE: MICHEL TEMER"}],"r":[{"f":"Oficial","dt":"30\/10\/2010","v":"1","t":"2","ht":"22:00:09","tf":"false","m":"N"}],"t":[{"vl":"0","vv":"0","e":"135804433","vnom":"0","s":"400001","c":"0","tv":"0","a":"0","vb":"0","st":"0","ea":"0","vn":"0"}]}

如何

json_解码（$your_字符串）？这不管用吗？
正确的链接就在您访问的页面上…@Chacha relaxy。如果是重复的行为，我支持你。但是这是一个没有找到正确链接的新用户，好吗？可能是Well的重复，例如：
$obj->{'c'}
将为您提供c的内容。请看这里的解释：我认为它实际上是
$array->c[0]->v
或其他东西。Json_decode在对象模式下解压它非常奇怪。
$before='{"c":[{"v":"0","e":"","n":"45","cc":"PSDB - PTB \/ PPS \/ DEM \/ PMN \/ PSDB \/ PT do B","nm":"JOSÉ SERRA","nv":"VICE: ÃNDIO DA COSTA"},{"v":"0","e":"","n":"13","cc":"PT - PRB \/ PDT \/ PT \/ PMDB \/ PTN \/ PSC \/ PR \/ PTC \/ PSB \/ PC do B","nm":"DILMA","nv":"VICE: MICHEL TEMER"}],"r":[{"f":"Oficial","dt":"30\/10\/2010","v":"1","t":"2","ht":"22:00:09","tf":"false","m":"N"}],"t":[{"vl":"0","vv":"0","e":"135804433","vnom":"0","s":"400001","c":"0","tv":"0","a":"0","vb":"0","st":"0","ea":"0","vn":"0"}]}';

print_r(json_decode($before));
