post获取的json数据 [{name:pm,value:224},{name:wd,value:25},{name:sd,value:34},]
如何截取 name＝wd 的value？
求代码。
------解决方案--------------------
$json = '[{name:pm,value:224},{name:wd,value:25},{name:sd,value:34}]';
$jsonarr = json_decode($json) ;
foreach ($jsonarr as $value) {
if($value->name == 'wd'){
echo $value->value.
;
}
}
