#11470 — glob patterns

   I don't understand when to use {},[] or () in php glob matching

I want to match one or more numbers, either an a,w or h, a dash and then 
a string.

120a-some_string or 1400w-some_string or 7h-some_string...

Is it:

glob('+{0-9}@{a,h,w}-some_string,GLOB_BRACE);

or is it?:

glob('+[0-9]@[ahw]-some_string');

or something else?

i would go for:
 > php -r " print_r(glob('[0-9]*[awh]-some_string')); "
Array
(
     [0] => 120a-some_string
     [1] => 1400w-some_string
     [2] => 7h-some_string
)
