将字符串拆分为零件并加载到数据库

I am trying to write a php script which would take a string value, really long one, like:

host.canada.example.com ID: 1402944178480070 Unix hostname: ns1.example.com IP address: 232.99.185.193 MAC address: 02:10:00:2b:33:fb Description: Type: KVM Type code: kvm Status: Virtualmin Status code: virt Status changed: 15/Aug/2014 07:40 OS: CentOS Linux OS code: centos Webmin version: 1.690 Webmin OS type: exampleOS Linux Webmin OS version: 6.5 Virtualmin version: 4.09.gpl Webmin URL: https://host.canada.example.com:10000/ Created: 16/Jun/2014 14:42 Age: 65 days, 3 hours, 36:00 minutes Kernel version: Linux 2.6.32-431.17.1.el6.i686 CPU architecture: i686 Attempt SSH login: Yes SSH login: root SSH password: gxzPksT2 SSH version: 2 SSH port: 22 Webmin same as SSH: No Webmin login: root Webmin password: 5VXrAQPTw Webmin port: 10000 Webmin SSL: Yes Start at boot: Yes Boot device: c Hosted on: canada.example.com KVM process ID: 7026 KVM total disk size: 81.50 GB KVM disk driver: VirtIO KVM high resolution graphics?: No Block spoofed IPs and MACs?: No Memory limit: 2 GB Maximum CPU use: Unlimited Virtual CPUs: 6 Virtual cores: 6 Disk space used on host: 81.50 GB IO class: 0 Allowed IPs: Any Resource accounting period: One month Start of period: 01/Aug/2014 00:00 (1707538 seconds ago) End of period: 20/Aug/2014 18:15 (234 seconds ago) System uptime over period: 19 days, 18 hours, 15:04 minutes (1707304 seconds) Memory used over period: 948.50 GB hours (3666407422164992 byte seconds) Memory average over period: 2147483648 bytes Memory average while up: 2147483648 bytes CPU allocated over period: 47425.11 percent hours (170730400 percent seconds) CPU used over period: 13760.24 percent hours (49536856 percent seconds) CPU used average over period: 29 percent CPU used average while up: 29 percent Disk limit over period: 30686.78 GB hours (118618837351399424 byte seconds) Disk used over period: 30686.78 GB hours (118618837351399424 byte seconds) Disk average over period: 69477279588 bytes CPU load: 0.43 0.37 0.34 Real memory: 1.85 GB Real memory free: 712.57 MB Virtual memory: 1.50 GB Virtual memory free: 891.25 MB Disk space: 78.74 GB Disk space free: 62.39 GB Filesystem: / size 78.74 GB used 12.34 GB free 62.39 GB Filesystem: /dev/shm size 946.59 MB used 0 bytes free 946.59 MB Running services: Apache Webserver, BIND DNS Domain, Postfix Mail Domain, Dovecot IMAP / POP3 Domain, SSH Domain, MySQL Database Domain Down services:

split it into parts and load to a MySQL database. If I output similar string putting it between <pre> and </pre> tags then I can see it is split to lines like:

but it still is just a string. I guess I could turn this into array, but it is still confusing how do I do it and how to make the php string to correctly put everything into right MySQL database tables.

Edit: I have some progress. With the following piece of code:

$string = '<pre>'.$string.'</pre';
$string = split("
",$string);
$func = function($value) { return preg_split("/\s{2,}/",$value ); };
print_r(array_map($func, $string));

I've got this array:

Now, let's guess there is a MySQL database with "id", "unix hostname", "ip address", etc. tables. How can I get value parts like "1402945178280070", "ns1.domain.tld", "232.99.185.193" from the array and to put them into corresponding database tables?

Unfortunately, I can't rely to array item numbers as they constantly change. I mean this following array member:

[2] => Array
    (
        [0] => 
        [1] => Unix hostname: ns1.domain.tld

could easily become:

[3] => Array
(
    [0] => 
    [1] => Unix hostname: ns1.domain.tld

next time.

    Well, you could try something like this:

    $string   = [your original long string];
$lines    = explode("
", $string); // Create initial raw array from the string at newline characters.
$hostname = array_shift($lines); // Remove the first hostname from the first index.
$data     = array('hostname' => $hostname); // Start the data array with the hostname first.

foreach ($lines as $line)
{
    $line = explode(': ', $line);

    // You can probably simplify this a LOT, but I wanted to break out what is happening
    $key  = strtolower($line[0]); // Set to lower case.
    $key  = preg_replace('/[^a-z0-9]+/', '_', $key); // Replace anything that is not a letter or a digit with an underscore.
    $key  = trim($key, '_'); // Remove leading or trailing underscores.

    $data[$key] = $line[1];
}

    Then you at least have a $data array that looks like this:

    Array
