Re: Basic Array Question

Perl calls "associative arrays" hashes. It makes sense and it saves you a bunch of syllables to use at a later date. Anyway, you set a key-value pair in a hash this way: $hash{$key} = $value; Therefore, if your array, @row, has two elements, and you want the first field to be the key and the second field to be the value, you would do: $frequency{$row[0]} = $row[1];

In fact, you might want to use more descriptive names in your while statement:

my %freq;

while (my ($page, $hits) = $cursor->fetchrow_array) {
  $freq{$page} = $hits;
}

Perl calls "associative arrays" hashes. It makes sense and it saves you a bunch of syllables to use at a later date. Yes to the latter, maybe to the former. The fact that associative arrays in perl are implemented using a hashing mechanism, is just an implementation detail that has no influence on how people use them. So I'm more or less unhappy with that name. I'd prefer "string-indexed arrays" any day, but of course, people with find that name too long, too.	[reply]

I wouldn't mind "map" (except that's overloaded) or "mapping", and Python calls them (or at least used to call them) "dictionaries", which also makes sense (except you tend to think of a dictionary as being sorted alphabetically).

This is one way: `while (@_ = $cursor->fetchrow) { $freq{$_[0]}=$_[1]; }` [download] What happens is you are associating the result to an anonymous array (@_)	[reply] [d/l]
