Translation Rules Query

Member Posts: 309
Been looking at an article and have a query on the following...
rule 2 /^123/ /456/
rule 3 /^123$/ /456/
It says
rule 2 replaces any number starting with 123 with a 456
rule 3 replaces only the number 123 as the source number with 456
Aren't these both the same thing? I'm not sure on the difference between Rule 1 and Rule 2. Could someone provide an example of these rules being utilized, hopefully seeing it will make it clearer?
Thanks

So for example the string '123' would match both, but '1234' would only match the first.An expert is a man who has made all the mistakes which can be made. -
