How would you change this:
a-10-b-19-c
into something like this:
a-10-b-20-c
using regular expressions in PHP?
The only solution I've found so far is:
- reverse the original string -> "c-91-b-01-a"
- find the first number -> "91"
- reverse it -> "19"
- turn in into a number (parseInt) -> 19
- add 1 to it (+1) -> 20
- turn it into a string again (toString) -> "20"
- reverse it again -> "02"
- replace the original match with this new number -> "c-02-b-01-a"
- reverse the string -> "a-10-b-20-c"
I was hoping someone on SO would have a simpler way to do this... Anyone?
