How to replace occurrences of “-” with an empty string?

Question

I have this string: \"123-456-7\"

I need to get this string: \"1234567\"

How I can replace occurrences of \"-\" with an empty string?

Answer 1

To be clear, you want to replace each hyphen (-) with blank/nothing. If you replaced it with backspace, it would erase the character before it!

That would lead to: 123-456-7 ==> 12457
