Embarrassed to ask this REGEX question, but...

[Jerred121]

So just when I think i'm getting the hang of REGEX, I realize that I suck still and I can't get this simple extraction to work... 

 

I want to extract the temp and the method separately:

 

Array
(
    [0] => Array
        (
            [0] => temp: 35.20c / 95.36f - axillary
            [1] => temp: 35.20c / 95.36f
            [2] => temp: 35.20c / 95.36f - oral
        )

    [1] => Array
        (
            [0] => 35.20c / 95.36f
            [1] => 35.20c / 95.36f
            [2] => 35.20c / 95.36f
        )

    [2] => Array
        (
            [0] => axillary
            [1] => 
            [2] => oral
        )

 

I'm even embarrassed to post my sorry pattern, but I'm sure you guys can figure it out.  As always, thank you!

Sorry, looks like I forgot to include a sample of the data:

 

temp: 35.20c / 95.36f - axillary

temp: 35.20c / 95.36f

temp: 35.20c / 95.36f - oral

 

As you can see the " - method" is optional.

Might be an easier way, but here is one:

 

preg_match_all('#^temp: ([^ ]*) / ([^- ]*)(?: - (.*))?$#m', $s, $m);
