解析JSON的有关问题

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 />}
