我正在使用php和数组,我有如下多个数组
Array
(
[0] => Array
(
[wallet_address] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
)
[1] => Array
(
[wallet_address] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
[2] => Array
(
[wallet_address] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
等等
我想用逗号将它们放在一个数组中,如下所示
$set = array("0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx","0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx","0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
我怎么能这么做?这是我目前的代码,但不工作,显示我相同的结果(0,1,2键),我错在哪里?
$GetUserFollower; //contaning multiple array value
$set=array();
foreach($GetUserFollower as $arr)
{
$set[]=$arr;
}
echo "<pre>";print_R($set);
原始数组是一个Assoc数组,因此钱包地址需要在循环中专门寻址。或者您可以使用array\u column()
内置函数来实现同样的功能。
$GetUserFollower; //contaning multiple array value
$set=array();
foreach($GetUserFollower as $arr)
{
$set[] = $arr['wallet_address'];
}
echo "<pre>";print_r($set);
或
$new = array_column($GetUserFollower, 'wallet_address');
print_r($new);
后果
Array
(
[0] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
[1] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
[2] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
你的评论让我觉得你想要一个没有键的数组,这是不可能的。如果您使用您在评论中显示的示例执行此操作
$set = array("0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx","0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx","0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
print_r($set);
你会看到的
Array
(
[0] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
[1] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
[2] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
在Foreach循环中,添加[0]
$set[]=$arr[0];
请试一试
