In a later mail the OP has mentioned that her list may be of the form my @ops_list = ("a", "b=7", "c=8"); The first element does not have a "=" in it. I am assuming that the key that she uses for search here is "a". Your code snippet will return an undef when called with some_func (@ops_list, "a")

Will this be sufficient? my($array) = ['a=1', 'b=2', 'c=3', 'd=4']; my($str) = 'd=43'; my($index) = indexOf($array,$str); print ("Index of $str in the array is = $index"); sub indexOf{ my($arr) = shift; my($val) = shift; for(my $i=0; $i < @{$arr}; $i++){ return($i) if($arr->[$i] eq $val);

RE: index inside foreach{ ..}

I don't know if you can do it using a foreach but I would use a for loop. It may be just a tad slower but you'll get the results you're looking for. Using the loop below will start at the last index of the array @a and loop down to the first (assuming that the first index of the array is 0). @a
