Question

我有一个mysql表，我保留了电子邮件地址。结构如下：

id    ||    email

但是，我如何在php中实际输出用逗号分隔的电子邮件地址？

提前感谢您的帮助！

Answer 1

使用：

<?php
 $query = "SELECT GROUP_CONCAT(t.email) AS emails
             FROM YOUR_TABLE t"

 // Perform Query
 $result = mysql_query($query);

 while ($row = mysql_fetch_assoc($result)) {
    echo $row['emails'];
 }

 // Free the resources associated with the result set
 // This is done automatically at the end of the script
 mysql_free_result($result);
?>

选项1：

$sql = "SELECT GROUP_CONCAT(email ORDER BY email ASC SEPARATOR ', ') AS emails FROM emails";
$res = mysql_query($sql);
list($emails) = mysql_fetch_row($res);

echo $emails;

选项2，以便您稍后可以对所有电子邮件执行更多操作：

$emails = array();

$sql = "SELECT email FROM emails ORDER BY email ASC";
$res = mysql_query($sql);
while ($r = mysql_fetch_object($res)) {
  $emails[] = $r->email;
}

// as a list
echo implode(', ',$emails);

// or do something else
foreach ($emails as $email) {
  // ...
}

做类似的事情：

while ($output = mysql_fetch_array($query_results)) {
  echo $output['id'] . ", " . output['email'];
}
