HTML中不需要围绕属性值的引号，但在某些情况下它们是必需的，例如当你必须在属性值中放置一个空格。
Quotes around an attribute value are not required in HTML, but they are necessary in some cases such as when you have to put a space inside your attribute value.
不带引号的属性值也必须不包含以下任何字符：
，'，=，>，<或`。当然，你可以有％，或者＃或£，但是没有反引号！
Unquoted attribute values must also not contain any of these characters:
", ', =, >, <, or `. Sure, you can have %, or # or £, but no backticks please!
如果你想从PHP设置属性值，你必须 []（使用 \）：
If you want to do set the attribute value from PHP, you have to escape the quote[^] (using \"):
echo"<option value=\"".
