数组到字符串连接

Question

我得到了下一个数组：

    Array ( 

[0] => Array ( [email] => xasxxxxxx@yahoo.com [btc] => 0.00287896 [tn] => 6.615 [address] => 2BY4HM [status] => pending ) 

[1] => Array ( [email] => xxxxx@yahoo.com [btc] => 0.04000 [tokens_given] => 5 [address] => xxXXxxxxxaaaxxXs [status] => pending ) 

[2] => Array ( [email] => xsxxxx@yahoo.com [btc] => 0.04000 [tokens_given] => 5 [address] => xxXXxxxxxaaaxxXs [status] => pending ) 

[3] => Array ( [email] => xssasas5@yahoo.com [btc] => 0.04000 [tokens_given] => 5 [address] => xxXXxxxxxaaaxxXs [status] => pending ) 

[4] => Array ( [email] => xxxxxx@yahoo.com [btc] => 0.04000 [tokens_given] => 5 [address] => xxXXxxxxxaaaxxXs [status] => pending )

)

我如何将变量中的所有'地址'作为以逗号分隔的字符串？

类似这样的事情

$ string =“1stadress，2ndaddress，3ndadress”等

我试过了：

$comma_separated = implode(",", $row['address']); // where $ row is the array above

它失败了。

Answer 1

您可以使用array_column和implode

echo implode(',',array_column($myarray,'address'));

Answer 2

循环通过数组并收集相关成员，我可以使用不明确的数组，这样可以在以后需要时重复使用

$buffer = [];
foreach($myArray as $id=>$data){
  $buffer[] = $data['address'];
}
$output = implode(',',$buffer);
