推荐答案

HTML 属性用空格分隔.要指定包含空格的值，您需要将其括在引号中，单 ' 或双 ".

The HTML attributes are separated by spaces. To specify a value, which contains spaces you need to enclose it in quotes, either single ' or double ".

<option value="some value" anotherAttribute=1></option>

因为在 PHP 中您已经使用了双引号，您现在可以使用单引号将 HTML 属性的值括起来.

Becuase in PHP you have already used double quotes you can use single quotes now to enclose the value of your HTML attribute.

echo "<option value='".$row['code']."' ></option>" ;

您也可以将标签之间的值作为内容，如果该值与显示的内容相同.

You could also put the value between the tags as the content, if the value and the displayed content is the same.

echo "<option>".$row['code']."</option>" ;
