Re: Find the word in Array, Hash, Scalar

Hello

Everything in foreach

@array_1 = ("cat", "rat", "lion");
@array_2 =("dog", "tiger");
$variable="horse";
%hash=("1" => 'peacock', "2" => 'duck')    ;

foreach (@array_1, @array_2, $variable, @hash{keys %hash})
{
    if ($_ eq "tiger")
    {
        print "\nfound $_";
    }
}

`@hash{keys %hash}` really is a bad idea... What will this do? it will create a list of all the keys in the hash, use that list in a hash slice and return all values. If you want to get all values of a hash then there is the values function... it is shorter, cleaner and more efficient. (Another possibilty would ofcourse be to use kapproach's approach, which is probably better)	[reply] [d/l]

Or, to expand on the parent poster's suggestion, stuff it all in a big array and then grep on it. Remember rule one...	[reply]
