PHP RegEx：“任何一个时期的标志，或至少一个短跑”
[英]PHP RegEx: “Either One Period Sign, Or At Least One Dash”
问题描述
I'm having trouble formulating this simple thing via regex, and would appreciate a bit of advice. 
我很难通过正则表达式来制定这个简单的东西，并且会很感激一点建议。
This tiny pattern says, "either one period sign, or one dash": 这个微小的模式说，“要么是一个周期标志，要么是一个短划线”：
[.-]
What I'm looking for is the pattern that would say instead, "either one period sign, or one or more dashes". 我正在寻找的是相反的模式，“一个周期符号，或一个或多个破折号”。
How can that be expressed? 怎么能表达出来？
Thank you in advance! 先感谢您！
