Hi people..

I'm populating an array, which I then use in a foreach statement to print into an html table.

The issue I have is that I'm getting duplicates in the array, so basically I want to check if the item exists in the array and then only add the new record if it doesn't exist.

I've tried turning the array into a hash, which works, but it seems to be a waste of time to drop the array into a hash every single time I need to check it. 

        if ($server eq 'lsrch1') {
            my %params = map { $_ => 1 } @lsrch1;
            if(! exists($params{$string})) {
                push (@lsrch1, $string);
            }
        }

Is there a quicker, more efficient way to do it? I suspect using grep would be even slower.

Thanks all
