Here is one way to do it... 
#!/usr/bin/perl

my $string = 'It was an intelligent stori';
my $matches = 0;

my (@chr) = split(//, $string);
foreach (@chr) {
$matches++ if ($_ =~ m/[iI]/); # match it & count
}


print "Content-type: text/html\n\n";
print "<html>String: $string<hr>Matches: $matches</html>\n";
