importVendors()

importVendors() -- Import a manufacturers' file to the database or to an array

Synopsis

require_once 'Net/MAC.php';

mixed importVendors (string $file [, boolean $doReturn=FALSE])

Beschreibung

This method will parse a manufacturers' file, such as the one from http://anonsvn.wireshark.org/wireshark/trunk/manuf, containing a list of MAC address prefix-to-vendor relationships. If the $doReturn parameter is FALSE, then the data will be imported into the database defined by the factory of this class. However, if $doReturn is TRUE, then the return will be an associative array with the key being the MAC address prefix and the data being an associative array with the keys 'vendor' and 'description'.

Parameter

  • string $file - The filename or URL of the manufacturers' file to parse

  • string $doReturn - If TRUE, an array will be returned, if FALSE, the data will be imported into the database.

Rückgabewert

mixed - If $doReturn is TRUE, the method will return an array. Otherwise, the method will return TRUE on success. A Net_MAC_Exception Exception object will be thrown on failure in either case.

Hinweise

Diese Methode kann nicht statisch aufgerufen werden.

This method can throw exceptions on error, so the method should always be called from inside a try/catch block.

Beispiel

Beispiel 54-1. Using importVendors() with a URL


<?php
require_once 'Net/MAC.php';
require_once 'MDB2.php';

$db_type = 'pgsql';
$db_host = 'localhost';
$db_user = 'username';
$db_name = 'dbname';
$db_pass = 'password';

$dsn = "$db_type://$db_user:$db_pass@$db_host/$db_name";

$dbh =& MDB2::factory($dsn);

if (MDB2::isError($dbh)) {
  echo "MDB2 Error: ".$dbh->getUserInfo();
}

$dboptions = array('tablename' => 'macvendors',
           'macaddrcol' => 'macaddr',
           'vendorcol' => 'vendor',
           'desccol' => 'description');

try {
  $nmh =& new Net_MAC($dbh, $dboptions);
} catch (Net_MAC_Exception $e) {
  echo 'Net_MAC Error: ' . $e->getMessage();
  exit;
}

try {
  $nmh->importVendors('http://anonsvn.wireshark.org/wireshark/trunk/manuf');
} catch (Net_MAC_Exception $e) {
  echo 'Net_MAC Error: ' . $e->getMessage();
  exit;
}
?>

This would output an error only if there is an error importing the file from the URL.

Beispiel 54-2. Using importVendors() with a file, returning an array


<?php
require_once 'Net/MAC.php';
require_once 'MDB2.php';

$db_type = 'pgsql';
$db_host = 'localhost';
$db_user = 'username';
$db_name = 'dbname';
$db_pass = 'password';

$dsn = "$db_type://$db_user:$db_pass@$db_host/$db_name";

$dbh =& MDB2::factory($dsn);

if (MDB2::isError($dbh)) {
  echo "MDB2 Error: ".$dbh->getUserInfo();
}

$dboptions = array('tablename' => 'macvendors',
           'macaddrcol' => 'macaddr',
           'vendorcol' => 'vendor',
           'desccol' => 'description');

$nmh =& Net_MAC::factory($dbh, $dboptions);
if (PEAR::isError($nmh)){
  echo 'Net_MAC Error: '.$nmh->getMessage();
}

$vendorArr = $nmh->importVendors('./manuf')
if (PEAR::isError(!$vendorArr)) {
  echo 'Net_MAC: ' . $err->getUserInfo();
  exit;
}

print_r($vendorArr);
?>

This would output the entire list of MAC address vendors on success and an error message on failure.
