我个人在项目中的写法:
//遍历二维数组
foreach($tmp_array as $key => $value){
//动态生成图片的URL
$attach_url = $this->qiniu_utils->get_download_url($tmp_array[$key][‘attach_save_name‘] , ‘7vih5p.com1.z0.glb.clouddn.com‘, ‘PRIVATE‘);
//赋值URL
$tmp_array[$key][‘attach_save_url‘] = $attach_url;
}
$result[‘feed_img_ids‘] = $tmp_array;
--------------------------------------------------------------------------- 以下是网上的参考答案
Q:
$arr = array(‘one‘=>array(‘name‘=>‘张三‘,‘age‘=>‘23‘,‘sex‘=>‘男‘),
‘two‘=>array(‘name‘=>‘李四‘,‘age‘=>‘43‘,‘sex‘=>‘女‘),
‘three‘=>array(‘name‘=>‘王五‘,‘age‘=>‘32‘,‘sex‘=>‘男‘),
‘four‘=>array(‘name‘=>‘赵六‘,‘age‘=>‘12‘,‘sex‘=>‘女‘));
foreach($arr as $key=>$value){
foreach($value as $key2=>$value2){
$arr[$ey][$value][$key2][‘age‘]= 55;
}
}
print_r($arr);
怎么给age赋一个新值?
A:
foreach($arr as $key=>$value){
$arr[$key][‘age‘]=55
}
看你的需求 这就行了
