Use a some text to match against where there's many places for a match
to occur. When you use the PREG_PATTERN_ORDER, for the order argument with
preg_match_all, it's like a global match, collecting the matches and
subpatterns (obtained by using parenthesis, which will 'remember' the
subpatterns) in the 2dim array for your viewing pleasure.
Something like that. I usually have to wrestle with it a bit to get it straight
how the results from the subpattern matches (from the memorizing parens) are
ordered in the array to get the a loop to spit everything back out correctly.
If your nesting parens, I think it's you just start counting the opening paren
from the left, and they'll match sequentially as indexes in the associated array
for that particular match. Well, the 0 index is the entire match, and the subpat
matches pick up at index 1.
But, if the winds blowing from the east, and .....
