How can I replace only the last occurence of an number in a string with php?
- by Shawn
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?
