I want to be able to generate an IF statement within a loop, and then execute it when the loop is finished.

I dont know how to do it.

For example, let's say I want to search for both the words cat and dog in a string. The code would look like this:


$str = "cat dog rat elephant giraffe";
$searchstr = "cat dog";

@array = split (/\s+/, $searchstr);

foreach $animal (@array)
{
  # Here I build my IF statement, which I will execute
  # when I have finished my loop!

  $execute .= "$str =~ /$animal/ && ";
}

#finish off the string...chop off hanging &&
$execute =~ s/ && //;

# HOW DO I DO THIS???
# THIS OBVIOUSLY DOESNT WORK !!!
if ($execute}
{
  print "Found a DOG and a CAT!\n\n";
}

I heard about the eval function, but I dont know how to use it! Any help will be most welcome! I feel that Perl has a way of evaluating expressions that are created on the fly.

Cheers!
