preg_match? Or something else?

I have an array that's created as follows:



$string = "73G 146C 311- 309.1C";

$arr = preg_split("/[\s]+/", $string);



Now I need to take each element in that array, and break them up even
further so that I get:



73G => "73" and "G"

146C => "146" and "C"

311- => "311" and "-"

309.1C => "309", "1", and "C" (notice 3 elements here)



I'm having a hard time trying to figure out what the proper regex would be
for this, or whether that's the right thing to do. So far I've gotten this:



preg_match("/^(?P\d+)(?P[A-Z-])/", $item, $matches);

print_r($matches);



Which gives me:



Array

(

[0] => 73G

[location] => 73

[1] => 73

[letter] => G

[2] => G

)

Array

(

[0] => 146C

[location] => 146

[1] => 146

[letter] => C

[2] => C

)

Array

(

[0] => 311-

[location] => 311

[1] => 311

[letter] => -

[2] => -

)

Array

(

)





However that's as far as it goes. For the other number it returns an empty
array and I know why, the decimal point. Now I can evaluate each $item
every time, see if they contain a decimal point, and pass it to a different
regex string, but that seems rather inefficient to me. So how can I do this
all in one fell swoop?



Anyone want to take a stab at it?

Conditionals are your friend!
