Another example on just how *stuck* I was! You're right ofcourse and I were
wrong when typing my example.
It's really two strings: $string1 and $string2.
Let me re-phrase my question a bit:
I want to compare the two strings and I want to extract those chars that are
matching each other in the first and second string (in order from the
beginning), and put them in a new string (not array as I mistakenly said
earlier).
So, if I have $string1 = "C:\Program files\directory1\directory2\directory3" $string2 = "C:\Program files\directory1\dir2\dir3"
then I want the output to be $string3 = "C:\Program files\directory1\";
How about something like this?
my $string3 = '';
for (my $i = 0; $i < length($sting1) || $i < length($string2); $i++) {
if (substr($string1, $i, 1) eq substr($string2, $i, 1)) {
$string3 = substr $string1, 0, $i + 1;
}
else { last; }
}This just compares a character at a time, to see if they are the same. If they are, we store that much. If not, we're all done.
Hope that helps.
