您需要修复所有正则表达式类。如果要在类中允许文本

-

，它必须是

[

之后的第一个字符。否则，它将被视为字符范围中的分隔符。例如

$Name_exp = "^[a-z .'-]=$";

应该是：

$Name_exp = "^[-a-z .']=$";

$Name_exp = "^[-a-z .']+$";

此外，此正则表达式只允许使用两个字符的名称，第二个名称必须是

=

。我怀疑这是

+

的打字错误，因此应该是：

$Name_exp = "^[-a-z .']=$";

$Name_exp = "^[-a-z .']+$";

您的所有其他regexp中都存在类似的问题，我不打算一一介绍并为您解决。

@nathan eregi是一个php函数（从php 5.3.0开始，此函数已被弃用。非常不鼓励依赖此功能。）
