在php中如何显示mysql结果？

Question

我有一个MySQL表，其中我保留电子邮件地址。结构如下：

id || email 

但是，如何实际输出这些电子邮件地址，用逗号分隔，在PHP中？

在此先感谢您的帮助！

Answer 1

用途：

<?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); 
?>

三打在谷歌为“PHP的MySQL”：http://www.freewebmasterhelp.com/tutorials/phpmysql

你可能需要在基础读了，它并不复杂，只需要几分钟的时间浏览一下它，让你开始。

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，这样你就可以与所有的电子邮件做多等一会：

$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) { 
    // ... 
}

做这样的事情：

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