Question

我在reg方面没有什么问题。我想澄清一点。

目前有一米,使用以下标准:

preg_replace("/[^a-zA-Z0-9 _-]/", "", "Example1:2@32");

给我“Example1232”

但是,殖民地也应被取代。我已经尝试过:

preg_replace("/[^a-zA-Z0-9 _-:]/", "", "Example1:2@32");

但这只是工作。有些人能否帮助我?

Answer 1

页: 1

preg_replace("/[^a-zA-Z0-9 _-:]/", "", "Example1:2@32"));

Answer 2

两种方法应当发挥作用:

escape the dash - or
put the dash - at the end of your regex, since inbetween two other characters it has a certain meaning (namely a range, as in a-z).
