php 二维数组遍历赋值

$arr = array('one'=>array('name'=>'张三','age'=>'23','sex'=>'男'),
'two'=>array('name'=>'李四','age'=>'43','sex'=>'女'),
'three'=>array('name'=>'王五','age'=>'32','sex'=>'男'),
'four'=>array('name'=>'赵六','age'=>'12','sex'=>'女'));

foreach($arr as $key=>$value){
foreach($value as $key2=>$value2){
$arr[$ey][$value][$key2]['age']= 55;

}
}

print_r($arr);

怎么给age赋一个新值？

Answer 1

foreach($arr as $key=>$value){
$arr[$key]['age']=55
}
看你的需求 这就行了

追问

Array( [total] => 2
[data] => Array ( [0] => Array( [trans_addtime] => 1400570630
[trans_alt1] => 0 ) ))
怎么给trans_addtime时间转赋值？
