Search for data in a log

I'm having trouble seeing where my error is, and also understanding and fixing the delay of query .

I have a function in PHP that does the parser of a log generated by OpenVpn . Below I will leave some lines of this log for you to help me.

CLIENT_LIST cliente1    120.203.57.20:56256 120.203.57.20   172756  170025  Wed May 25 08:26:39 2016    1464175599  UNDEF

The function that parses each row of this log and stores it in a table in the database:

$log = "log.log";

ovpnParser($log, $con);

function ovpnParser($log, $con)
{
  echo '<script>console.log("testing...")</script>';
  $inclients = false;
  $handle = fopen($log, "r");

  $inclients = false;
  while (!feof($handle))
  {
    $line = fgets($handle, 4096);

    if (substr($line, 0, 11) == "CLIENT_LIST")
    {
      if (preg_match("/CLIENT_LIST\t{1,}UNDEF(.*)UNDEF/", $line))
      {
        $inclients = false;
        echo '<script>console.log("client is not on the list...")</script>';
      }
      else
      {
        $inclients = true;
        echo '<script>console.log("client is in the list...")</script>';
      }
    }

    if ($inclients)
    {
      preg_match("/CLIENT_LIST(.*)UNDEF/", $line, $conteudo);

      $partes = preg_split("/\t{1,}/", trim($conteudo[1]));

      $sql            = "SELECT comName FROM vpn
                        WHERE  comName = '{$partes[0]}'";
      $query          =  mysqli_query($con, $sql);
      $numeroDeLinhas =  mysqli_num_rows($query);

    if ($numeroDeLinhas == 0)
    {
      $sql = "INSERT INTO vpn (comName, realAddr, virtAddr, byR, byS, since, sinstamp, blockstatus)
            VALUES ('{$partes[0]}', '{$partes[1]}', '{$partes[2]}', '{$partes[3]}', '{$partes[4]}', '{$partes[5]}', '{$partes[6]}', 'true')";

      $query = mysqli_query($con, $sql);
      echo '<script>console.log("new client added to the list...")</script>';
    }
    elseif ($numeroDeLinhas > 0)
    {
      clientcmp($conexao, $partes[0]);
    }
  }
  $inclients = false;
}
echo '<script>console.log("the test is finished...")</script>';

}

Note: I put some echo so that I can track exactly where the code is currently running.

In addition to doing this parser to be able to insert into a table in the database, I need to know whether the client is connected or not.

The logic is this: when running parser , it will check in the database if there is any client with that name, if it does not exist, that client is inserted in the database, and if the client is present in the log, that it has vpn connected.

Now the part that I am not able to do: if the client is in the database but it is not in this log file, this means that it is with vpn disconnected!

This log file is updated every 1 minute, ie this parser will run every 1 minute.

In the table in the database, I added a "connectedOr" column, if it is connected, I have to store true , if it is not connected, I have to store false .

The function I had done for this purpose, is this:

function clientcmp($conexao)
{
  $start = microtime(true);
  $query = mysqli_query($conexao, $sql);
  $str1 = "kg-01239918000150"; // nome do log


  $x = array();
  while($row = mysqli_fetch_assoc($query))
  {
    $x = $row['comName'];
    if ($str1 == $x)
    { // está no log e está no banco de dados
      $sql = "UPDATE vpn SET connectedOr = 'true' WHERE comName = '{$x}'";
      $queryy = mysqli_query($conexao, $sql);
      echo '<script>console.log("cliente consta no log e consta no banco de dados.")</script>';
    }
    elseif ($str1 != $x)
    {
      $sql = "UPDATE vpn SET connectedOr = 'false' WHERE comName = '{$x}'";
      $queryy = mysqli_query($conexao, $sql);
      echo '<script>console.log("cliente não consta no log e consta no banco de dados.")</script>';
    }
  }
  $time_post = microtime(true);
  $exec_time = ($time_post - $start)/60;
  echo $exec_time;
}

The way I did to find out if it is connected or disconnected it ALWAYS checks the name of the client1, never going to the other clients, since the database insertion is working correctly.

Thank you!
