"id":9037,"isp":"2","issuerId":7,"name":"网通6-13区"，中提取出来的id为:9037，isp为:2， name为:网通6-13区

$s = '{"result":"1","realms":[{"activeMode":"0","chargeType":"0","closeDate":null,"createDate":{"date":6,"day":4,"hours":0,"minutes":0,"month":7,"nanos":0,"seconds":0,"time":1249488000000,"timezoneOffset":-480,"year":109},"emigrateLimit":"1","gameId":9,"id":9037,"isp":"2","issuerId":7,"name":"网通6-13区","state":"1","subdbId":24},{"activeMode":"0","chargeType":"0","closeDate":null,"createDate":{"date":10,"day":2,"hours":0,"minutes":0,"month":7,"nanos":0,"seconds":0,"time":1281369600000,"timezoneOffset":-480,"year":110},"emigrateLimit":"1","gameId":9,"id":7090026,"isp":"2","issuerId":7,"name":"网通53区[魔幻圣域]","state":"1","subdbId":26}]}';$pat = '`,"id":(\d+),"isp":"(\d+)","issuerId":(\d+),"name":"([^"]+)"`';
preg_match_all($pat, $s, $arr);
print_r($arr); 

Answer 3

$pattern = '/"id":\d+,"isp":"\d+","name":"[^,.]+"/';preg_match_all($pattern, $string, $match);print_r($match[0]);//过滤掉你不要的内容

Answer 4

这个就是json格式，不必要再写正则的

Answer 5

php对于json的编码格式还是很复杂的，用正则解析json恐怕是得不偿失。
建议楼主仔细研究一下json的格式说明。
