Looping through an array

[Mrclean78]

I need to write a loop that parses form data against an array. The form data is in the scalar, $search. The array contains keywords that should be matched, and is called @Keywords. What type of loop should I do? I'm thinking a foreach because I need all values of the array checked. But I'm not sure how to get the program to search for each variable. Any thoughts? Thanks.

You could use a for loop, but this is more of a situation for grep.

my @matches = grep { /$search/ } @Keywords;

[Mrclean78]

the new array, @matches will then take all of the keywords that match and store them. Now, I need to say something like this:

if (@matches "equals one or more words" in @Keywords)
{
Save to external file A; #I have this
}
else
{
Save to external file B;
}

What can I use for "equals one or more words"?

Thank you.

If you mean by words that it matches one of more elements in @Keywords then it is as simple as:

if (@matches > 1) {}
