You can try it by yourself:
#!/usr/bin/perl -w
use strict;
use CGI qw(:cgi);
foreach my $key ( param() ) {
my $value = param($key); # Fetch the parameter value
$value =~ s/^\s*|\d*\s*$//g; # Strip whitespaces and trailing digits
param( $key, $value ); # Reassigning the value in the parameter
}
# We verify the parameters to see if the values were changed
foreach ( param() ) {
print "$_ => '", param($_), "'\n";
}
__END__
