Is there an equivalent to PHP's strlen method in Ruby?
在Ruby中有相当于PHP的strlen方法吗?
I know about Ruby's String#count method, but it requires that I define a set of characters to count. In my situation, I want to count ALL characters, not just certain characters.
我知道Ruby的String#count方法,但它要求我定义一组字符来计算。在我的情况下,我想要计算所有字符,而不仅仅是某些字符。
