Urgh, regular expressions

Anyone fancy helping me with some regex?

I need to match "1d 1h 1m"
Where the user could just enter 1m or 1h or 1d or a combination of the three.

The numbers can change for example 2d 5h 24m.

I hate regex.

Code:

\d+d \d+h \d+m

cheers Spunkey - used this site before.

I should have said, it wasn't this part that was a struggle. It was the either or part.

I.E still matching:

1d
or
60m
or 1d 50m

etc. Is this possible?

Ah sorry, missed that bit.

To cover those you would need to include the 'or' operator, |

Code:

\d+d|\d+h|\d+m

I wish I'd known about this site a week ago, could have saved me several hours! Cheers for the link.
