include_once('db.php'); // database class
$dbase['host'] = 'asdf';
$dbase['user'] = 'asdf';
$dbase['pass'] = 'asdf';
$dbase['name'] = 'asdf';
$db = new DB($dbase);

// SELECT `meta_value` FROM `wp_usermeta` WHERE `meta_key`='password'

$result = $db->query("SELECT * FROM `wp_usermeta` WHERE `meta_key`='user_email'");
while ($row = $result->fetch_array()) {
    echo $row['meta_value'];
}
?>

推荐答案

试试这个查询。

SELECT 
wp1.meta_value AS first_name, 
wp2.meta_value AS last_name
FROM 
wp_usermeta wp1
INNER JOIN
wp_usermeta wp2
ON ( wp1.user_id = wp2.user_id )
WHERE 1
AND wp1.meta_key = "first_name"
AND wp2.meta_key = "last_name";
GROUP BY wp1.user_id;
