php正则匹配字符串中JSON的问题

[池大大]

$html = 'id=007&enc=Hg27sDS7&data=ISJsf2UF{"bind_card_list":[{"type":"1","code":"CCB","name":"建设银行","id":"54321","card_last":"8301","card_top":"621424","phone":"13298363188"},{"type":"0","code":"CCB","name":"建设银行","id":"12345","phone":"13224422188"}],"member_id":"12345","merchant_id":"0"}';

我想取出里面的json，请教一下改如何操作，如果正则的话该如何写匹配，谢谢各位了！！！

<?php

preg_match("/{.+}/", $a,$b);
$c = json_decode($b[0],1);
print_r($c);

parse_str($html,$arr);
echo substr($arr['data'],strpos($arr['data'],'{'));

这个是很简单的正则匹配，也可以使用一些php函数来完成，

$data = json_decode(strstr($html, '{'), true);

或者用explode和substr分割

    [member_id] => 12345
    [merchant_id] => 0

我自己运行了一下，我服务器的$a是动态获取的，我想把array前面的都丢掉，如何才能丢掉啊,用您这个方法能把示例中的前面部分丢掉，但是将字符串$a替换成我服务器上的数据就丢不掉前面的了，请问该如何操作，谢谢了！

不用正则

$html = 'id=007&enc=Hg27sDS7&data=ISJsf2UF{"bind_card_list":[{"type":"1","code":"CCB","name":"建设银行","id":"54321","card_last":"8301","card_top":"621424","phone":"13298363188"},{"type":"0","code":"CCB","name":"建设银行","id":"12345","phone":"13224422188"}],"member_id":"12345","merchant_id":"0"}';

parse_str($html, $a);
echo strstr($a['data'], '{');

用正则

$html = 'id=007&enc=Hg27sDS7&data=ISJsf2UF{"bind_card_list":[{"type":"1","code":"CCB","name":"建设银行","id":"54321","card_last":"8301","card_top":"621424","phone":"13298363188"},{"type":"0","code":"CCB","name":"建设银行","id":"12345","phone":"13224422188"}],"member_id":"12345","merchant_id":"0"}';

preg_match('/\{.+\}/s', $html, $m);
echo $m[0];

均可得到：{"bind_card_list":[{"type":"1","code":"CCB","name":"建设银行","id":"54321","card_last":"8301","card_top":"621424","phone":"13298363188"},{"type":"0","code":"CCB","name":"建设银行","id":"12345","phone":"13224422188"}],"member_id":"12345","merchant_id":"0"}

你是要拿data吧

$html = 'id=007&enc=Hg27sDS7&data=ISJsf2UF{"bind_card_list":[{"type":"1","code":"CCB","name":"建设银行","id":"54321","card_last":"8301","card_top":"621424","phone":"13298363188"},{"type":"0","code":"CCB","name":"建设银行","id":"12345","phone":"13224422188"}],"member_id":"12345","merchant_id":"0"}';

preg_match('/\{(.*)\}/s', $html, $matches);
$data = json_decode($matches[0], true);
print_r($data);
