不能使用“ - ”变量名？ [英] Cannot use "-" in variable names?

问题描述

以下是错误：


<？php

$ super-man = 100;

？> ;


解析错误：解析错误，第2行/test.php中出现意外''=''


我明白了; - "标志被视为运营商。

有没有办法解决这个问题？我需要 - 变量名。


谢谢，

罗斯

The following gives an error:

<?php
$super-man=100;
?>

Parse error: parse error, unexpected ''='' in /test.php on line 2

I understand that the "-" sign is seen as an operator.
is there a way to get around this? I need to have "-" in variable names.

Thanks,
Ross

推荐答案

super- man = 100;

不，你不能使用 - 登录变量。您可以使用_。

No, you cannot use the "-" sign in variables. You can use "_".
