? means "maybe" in some other place in PCRE. Or maybe that's POSIX.

? directly after an expression is equivalent to {0,1} (maybe) but after a
quantifier (*, +, {}) means ungreedy
I kind of talked about this in the reply to richard the .*? is exactly
the same as doing .*(?U)
an inline modifier to the previous expression.
That makes me wonder.. according to the docs U inverts greediness, if
you have...
/foo.*?bar/U
does that make .*? a greedy .*
