lua - Look for multiple characters using string.gsbu -

i use string.gsub search through phone number field , remove "-" or spaces.

is there way combine 2 statements have below one?

local phonenumber = string.gsub("123-123-1234", "-", "") phonenumber = string.gsub(phonenumber , " ", "") 

yes. square brackets used group multiple elements in lua patterns

local phonenumber = string.gsub("123-123 -1234", "[- ]", "")
