解析JSON的问题

<br />
{<br />
	"code":"A0001",<br />
	"serverTime":12345,<br />
	"data":[<br />
		{"epgId":"1103226854","endTime":"12000"},<br />
		{"epgId":"1103226855","endTime":"12300"},<br />
		{"epgId":"1103226857","endTime":"12350"},<br />
		{"epgId":"1103226858","endTime":"12356"}<br />
	]<br />
}<br />

假设有这一段JSON数据，需要获得其中 第一个endTime值大于serverTime值(12345)那一项中epgId的值(12350)


------解决方案--------------------

$s='{<br />
    "code":"A0001",<br />
    "serverTime":12345,<br />
    "data":[<br />
        {"epgId":"1103226854","endTime":"12000"},<br />
        {"epgId":"1103226855","endTime":"12300"},<br />
        {"epgId":"1103226857","endTime":"12350"},<br />
        {"epgId":"1103226858","endTime":"12356"}<br />
    ]<br />
}';<br />
$arr=json_decode($s,true);<br />
foreach($arr['data'] as $v){<br />
     if($v['endTime']>$arr['serverTime']){ <br />
	     echo $v['epgId'];<br />
		 break;<br />
	 }	   <br />
}
