php – 在HTML表单下拉菜单中从DB连接的两个字符串之间添加空格很困难

我从同一个表中的2个DB列中提取数据,以 HTML格式填充下拉菜单.虽然我确实获得了两个数据,但我似乎无法用空格分隔它们.下面的代码是我这样做的一般尝试,但我尝试更改和省略空格的引号以及用单引号和双引号括起firstname和lastname.但似乎没有任何效果.到目前为止我离开了：Firstnamelastname.

<?PHP
        //db connection
            MysqL_connect('localhost','root',"");
            MysqL_select_db('recy');

            $sql = "SELECT CONCAT(firstname,' ',lastname) FROM technicians";
            $result = MysqL_query($sql);

            echo "<select name='firstname','lastname'>";
            while ($row = MysqL_fetch_array($result)) {
                echo "<option value'" . $row['CONCAT(firstname,lastname)'] . "'>" . ucwords($row['CONCAT(firstname,lastname)']) . "</option>";
            }
            echo "</select>";
        ?>

任何建议或建议表示赞赏.

CONCAT_WS,是包含分隔符的MysqL函数所以..

$sql = "SELECT CONCAT_WS(' ',firstname,lastname) as name FROM technicians";

然后使用$row [‘name’]

我添加了别名作为名称,使生活更轻松

CONCAT_WS() stands for Concatenate With Separator and is a special form of CONCAT(). The first argument is the separator for the rest of the arguments. The separator is added between the strings to be concatenated. The separator can be a string,as can the rest of the arguments. If the separator is NULL,the result is NULL.
