Response to: Do it over again with Perl
Ultimately, you'll want to either look at or join the osx@perl.org list. You can see the archives here (there are some mentions of DBI). I've gone through a lot of Perl installations on my perl box, so, in my case, I just had to: sudo perl -MCPAN -eshell install Bundle::DBD::mysql Sat through a few errors, and when things were all finished, this script worked correctly (it assumes the database has been created as per the PHP script, and that some data has been entered). #!/usr/bin/perl use DBI; $dsn = "DBI:mysql:database=test;host=127.0.0.1;"; $dbh = DBI->connect($dsn, "root", ""); $sth = $dbh->prepare("SELECT * FROM wisdom"); $sth->execute; while (my $ref = $sth->fetchrow_hashref()) { print "$ref->{'id'}: $ref->{'author'} sez: $ref->{'wisdom'}\n"; } $sth->finish;

  what does the 2 lines below do?
  
  sudo perl -MCPAN -eshell
  install Bundle::DBD::mysql
  
  The 2nd one looks to install the mysql database driver for dbi, but the 1st one I'm clueless on. Is there something similar to instal the acutal DBI module? Thanks.

  "sudo" says to run the next command as the root user. "perl" starts the perl interpreter, and automatically loads in a module called "CPAN" ("-MCPAN" is equivalent to "use CPAN;"). Finally, "-e" is the "execute this perl code" command, and we're saying to execute the "shell" command of CPAN.
  
  The second command installs the actual module. If you know your module name, you can use it - so "install XML::Parser", "install LWP::Simple", "install DBI::mysql", and so on and so forth. If you do the "Bundle::DBD::mysql" as above, then you don't have to worry about installing the matching DBI module - it's contained within this "Bundle".
