//要把每个 ["uptime"]=>string(19) "2014-11-08 17:25:22" 里面的日期换成‘xxxx-xx-xx’格式
使用foreach ($array as &$arr){
$arr['uptime'] = date('Y-m-d', strtotime($arr['uptime']));
}本回答被提问者采纳
$arr[$key]['uptime'] = '替换时间格式';
}
foreach($a as $v)//循环取出$a里面的数组
{
$v['uptime']=substr($v['uptime'],0,10);//截取日期前10位，就是xxxx-xx-xx
//$v['uptime']=date('Y-m-d');//如果是取当前日期就是这个
}
foreach ($robot as &$v){
$v['uptime'] = date("y-m-d",strtotime($v['uptime']));
}
