php数组增加新的键值对

加一个取地址符&

$result = array(

​ [detail] => Array
​ (
​ [0] => Array
​ (
​ [name] => php
​ [weight] => 10
​ [region] => sz
​ )
​ )

)

$Res = Array

(

​ [detail] => Array

​ (

​ [0] => Array

​ (

​ [vbcId] => 3

​ [vpcId] => 688

​ [vbcInstanceId] => 10

​ )））

foreach ($Res['detail'] as &$data){    
	foreach ($result['detail'] as $row){        
		if ($data['regionId'] == $row['regionId']){            
			$data['vbcgwId'] = $row['vbcgwId'];            
			$data['uniqVbcgwId'] = $row['uniqVbcgwId'];            
			$data['gwIp'] = $row['instance'][0]['gwIp'];        
			}    
	foreach ($resultInstanceNum['detail'] as $num){        
		if ($data['vbcId'] == $num['vbcId']){            
			$data['vbcInstanceNum'] = $num['vbcInstanceNum'];            
			$data['lastUpdateStateTime'] = $num['lastUpdateStateTime'];        
			}    
		}    
	}
}

在$data 前加一个取地址符&
