group similar data in a string?

[ktsirig]

Hello all
I didn't know a good way of naming my question, so I am getting straight to the point:
I have a string like the following:

Code: Select all

-----MMMMM------IIIII----MMM---OOOO---I---MMMM-----

Is there any way I can gather and group my information and get, for example:

Code: Select all

6-10:M
17-21:I
26-28:M
32-35:O
39:I
43-46:M

Thank you in advance.

PHP has a ton of string manipulation functions.

I would grab what I need from the string and build an array. Maybe look at substr() or substr_count().

Good Luck,
