php/mysql: get data from one table, convert and insert in another table

Ok I will try to explain, (I am Portuguese lol).

I have a Database where I have the fallowing MySQL:

Database: ad
Table: notebooks
Fields: ID, tag, so, lastlogon, lastlogh

My ldap query gets data from ldap server (active directory) and stores it in my MySQL database (ad/notebooks). I get tag which is tag number is unique. I get so which is the OS installed in the notebook. I get lastlogh which is the last logon time stamp, and it is unique too. ID field is auto increment and key but I can set the tag filed to be key.

I have a config_notebooks.php where I set all the variables to connect to ldap and MySQL servers.

<?php
/*------------------------------------------------------------------------*/
//setting your variables
/*------------------------------------------------------------------------*/
//ldap host
$host = "ldap://HEICPT1VIA01.HEIWAY.NET";
//ldap user
$user = "domainuser";
//ldap password
$pswd = "pssw";
//ldap base structure
$dn = "OU=NotebookM2,OU=WorkstationsM2,OU=PT1,DC=heiway,DC=net";;
//attributs to search and get
$attrs = array("cn","operatingsystem","lastlogon");
//sql host
$sqlhost="localhost"; 
//sql user
$sqluser="root";
//sql password
$sqlpswd="";
//sql database
$database="ad";
//sql table
$table="notebooks";
?>

Now the query script

<?php
/*------------------------------------------------------------------------*/
//Query script
/*------------------------------------------------------------------------*/
include 'config_notebooks.php';
$filter = $_POST['filter']."=".$_POST['keyword']."*";
//connect to db
$con = mysql_connect("$sqlhost","$sqluser",""); 
if (!$con) 
{ 
die('Could not connect: ' . mysql_error()); 
} 

//connect to active directory
$ad = ldap_connect($host)
  or die( "Could not connect!" );
  
  // Set version number
ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3)
 or die ("Could not set ldap protocol");
  
  // Binding to ldap server
$bd = ldap_bind($ad, $user, $pswd)
  or die ("Could not bind");

$search = ldap_search($ad, $dn, $filter, $attrs)
      or die ("ldap search failed");

$entries = ldap_get_entries($ad, $search);
$sel = mysql_select_db("ad", $con); 
if (!$sel) 
{ 
die('Could not select DB: ' . mysql_error()); 
} 

for ($i=0; $i<$entries["count"]; $i++) 
{ 

$tag = $entries[$i]["cn"][0]; 
$so = $entries[$i]["operatingsystem"][0]; 
$lastl = $entries[$i]["lastlogon"][0];

     
        mysql_query("
        INSERT INTO 
            $table (tag, so, lastlogh)
        VALUES 
            ('$tag', '$so', '$lastl')
            ON DUPLICATE KEY UPDATE         
        tag='$tag',
        so='$so',
        lastlogon='$lastl'
        ");

} 
mysql_close($con); 
ldap_unbind($ad);
if ($entries["count"] > 0)
header("Location: notebooks_list.php")
?>

In this query the last logon timestamp is coded like 130276262860634000

So I can export everything to excel and decode it, but I found a code that does that, so it saves time. I created a new field in the database (lastlogon) and I need to fetch the data from lastlogh field, decode with the new script and store it in the lastlogon field.

This is the script that I found:

<?php
function adConvert ($ad) {
  $seconds_ad = $ad / (10000000);
   //86400 -- seconds in 1 day
   $unix = ((1970-1601) * 365 - 3 + round((1970-1601)/4) ) * 86400;

   $timestamp = $seconds_ad - $unix; 
   $normalDate = date("F d, Y", $timestamp);

      return $normalDate;
}

//example: echo adConvert($ad);
?>

Answer

Using Mysql API

$res = mysql_query("SELECT * FROM $table");
while($row = mysql_fetch_assoc($res)) {
  $logon_ts = adConvert($row['lastlogh']);
  mysql_query("UPDATE $table SET lastlogon = '$logon_ts' WHERE tag='$row[tag]'");
}

I hope this solves your problem.

Note: Mysql API is deprecated as of PHP 5.5.0. So, It’s highly recommended to use Mysqli API for newer developments.
