implode（）;不分离阵列

Question

结果就是电子邮件根本不分离。

$query = "SELECT email FROM wp_newsman_lst_wp_users"; 
$result = mysql_query($query); 

while($row = mysql_fetch_array($result)) 
{ 
    $new_array[$row['email']]['email'] = $row['email']; 
} 

foreach($new_array as $array) 
{  
    $to = $array['email']; 

    $mail_list = implode(", ", (array)$to); 
} 

echo $mail_list; 

结果只是电子邮件根本没有分开。

Answer 1

你必须采取foreach循环之外implode()调用，因此使用这样的：

foreach($new_array as $array) {  
    $to[] = $array['email']; 
    //^^ So you actually have a array 
} 

$mail_list = implode(", ", $to); 
      //^^^^^^^ Outside of the foreach loop
