I know this isn't the best way to parse it, but I need to check the
$ENV{'QUERY_STRING} for some values.
I originally had =~ /^limit=([0-9]{1,3})$/ which worked. But I
tried to replace the ^ with [&^] and the $ with [&$] to allow the
string to be part of a longer string attached with an & on either
side.
The point is, the [&^] doesn't seem match either ^ or &, like I want to.
Why is this? How do I match ^ or &?
(I really should just split on & and grep or whatever, but...)
[ and ] define a character class and ^ means something different inside a
character class. You need to use alternation instead.
=~ /(?:^|&)limit=([0-9]{1,3})(?:&|$)/
