Nested quantifiers in regex

1st time i'm facing this error...

there's few reason why this happen.

base on article at perlmonks,

if u use regex like this


and ur $match_string containing '???' it will return error like this.

to solve this, add Q...E at ur regex..


this will ignore other special chars that used by regex in ur string.

but, at my error.. i'm mistakenly put extra syntax when trimming my url..

my $urls =~ trimURL();

that produce this error..

so i just remove the '~' at it work fine now... hehehe.. silly mistake.. again
