I am trying to match words or complete phrase (excluding special characters)

Do you have a list of these special characters or do you mean all
non-alphanumeric and non-whitespace:
#!/usr/bin/perl
use strict;
use warnings;
while( <> ){
if( /[^[:space:][:alnum:]]/ ){
print "invalid: $_";
}
}
__END__
I need to ensure users cannot feed my program with special characters so I
tried this below, but it doesn't match correctly.
You can escape Perl's meta-characters with quotemeta()or using \Q and \E
in the regualr expression.
See:
perldoc -f quotemeta http://perldoc.perl.org/functions/quotemeta.html
perldoc perlretut http://perldoc.perl.org/perlretut.html
perldoc perlre http://perldoc.perl.org/perlre.html

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
Eliminate software piracy: use only FLOSS.
