解析JSON的问题

Question

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

Answer 1

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