You can do it a couple of ways (there's ALWAYS more than one way to do it
in Perl). Do you want to find the first element that meets the criteria,
or all of them (you might have duplicates).
The most generic way is to use a foreach loop:
foreach $i (@array) {
if($i eq $item_to_match) {
$match = $i;
$found = 1;
last;
}
}
if($found) {
#do stuff
} else {
#do other stuff
}
You can get fancier if you want to find a subset of elements that match
your search criteria:
my @matched = grep { /030/ } @array;
The test inside of the grep block can be as complex as you need it to be.
