Re^2: Multiple file handles

If I were to use a file as opposed to a DB, I'd most definitely use JSON. Cross-platform, cross-language, and web API ready.

codes.json

{
    "91280": "CA",
    "61682": "NY",
    "23823": "WA"
}
[download]

Perl script:

use warnings;
use strict;

use JSON;

my $file = 'codes.json';

my $data;

{
    local $/;
    open my $fh, '<', $file or die $!;
    my $json = <$fh>;
    $data = decode_json $json;
}

print "$_: $data->{$_}\n" for sort keys %$data;
[download]

Output:

23823: WA
61682: NY
91280: CA

Thats actually a really good idea, We do use alot json stuff here, this might be a simpler way for me to do this, because I'd like to create 2 versions where I can run one on my machine, then use another to reference the database, but still not sure if I could reference mysql database on my local machine. i'll post more data once I get that connection working. This is what I have so far though. `my $database = "asterisk"; my $user = "root"; my $host = 192.168.8.50; my $password = 123; my $dbhA = DBI->connect("DBI:mysql:$database,$host","$password") o +r die "Couldn't connect to database: ".DBI->errstr;` [download] using DBI What would you recommed DBI vs DBD::mysql?

DBI is the plumbing; DBD::mysql is the fitting. You need both. From the doc for DBD::mysql (plus your error handling): `my $dsn = "DBI:mysql:database=$database;host=$hostname;port=$port"; my $dbh = DBI->connect($dsn, $user, $password) or die "Couldn't connec +t to database: ".DBI->errstr;` [download] Set up all those variables then use that exact code snippet and it should work for you. Hope this helps! The way forward always starts with a minimal test.	[reply] [d/l]

Yeah, that helped alot, I was trying to find an example where they use the dsn in the connect statement, wasn't sure I was doing it right since it kept failing, probably just need to make sure its got the right credentials since we have like 5 different servers for similar things.	[reply]
