Question

I’m trying to find a way to break a string at the second last comma, for example:

piece 1, piece 2, piece 3, piece 4, piece 5, piece 6, piece 7 should be 2 parts:

piece 1, piece 2, piece 3, piece 4, piece 5 and

piece 6, piece 7

and

piece 1, piece 2, piece 3, piece 4, piece 5 should be:

piece 1, piece 2, piece 3 and

piece 4, piece 5

Is there a string manipulation to search the string for a character and identify the position of the second last instance of that character?

I thought about exploding the string by , then gluing the last 2 to make part 2, and gluing however many first ones (varies) to make part 1, but I think that might be overkill. Any string manipulations for this?

Answer 1

Use strrpos to find the position of the last comma.

Use strrpos with the last position as the offset to find the 2nd last comma.

Break the string with substr.
