PHP 从表行中检索数据并将其存储到变量

我想这些问题已经说明了一切。我的查询结果会生成与条件匹配的行。我想从每个表列中获取每个数据并将其放入一个变量中。

$getinfo = "select 
                   user_firstname, 
                   user_middlename, 
                   user_lastname 
              from tempuserinfo 
             where user_email ='$ead' 
               and activation_code='$eac'";

$query = mysql_query($getinfo, $db);
if(!$query) {
    echo'something went wrong.';
} else {
    //put them into variables
    $firstname = mysql_fetch_object($query, 'user_firstname');
    $middlename = mysql_fetch_object($query, 'user_middlename');
    $lastname = mysql_fetch_object($query, 'user_lastname');
}

如果你得到多个结果，你可以像这样循环它们：

$getinfo = "select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email ='$ead' and activation_code='$eac'";
$query = mysql_query($getinfo, $db);

while ($row = mysql_fetch_array($query)) {
    $firstname = $row['user_firstname'];
    $lastname = $row['user_lastname'];
}

如果您只返回一行（请确保在 SQL 语句中添加 LIMIT），那么您可以使用如下内容：

$getinfo = "select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email ='$ead' and activation_code='$eac'";
$query = mysql_query($getinfo, $db);

$row = mysql_fetch_array($query);

$firstname = $row['user_firstname'];
$lastname = $row['user_lastname'];
