Fix php_browscap.ini for PHP

This class parses, fixes and prepares php_browscap.ini into browscap.ini for PHP. It also detects if the latest version needed to download.

<?php
/** from localhost to fetch and prepare the browscap.ini file
* @author Son Nguyen
* @since 8/25/2006
* @package Framework
* @subpackage Lookup
*/
class CBrowsCap {
 private $mTmpFileName = 'php_browscap.ini'; // tmp file before fixing
 private $mDownloadURL = 'http://browsers.garykeith.com/stream.asp?PHP_BrowsCapINI';
 /** constructor */
 function __construct() {}

/** get the version string from the file */
 function getVersion($pFile,$pCheckExisted) {
  $vVersion = NULL;
  if ($pCheckExisted && !file_exists($pFile)) {
   return NULL;
  } // fi

$vContent = file_get_contents($pFile,FALSE,NULL,0,500);
  if (preg_match('/version=(.*)/i',$vContent,$vMatches)) {
   $vVersion = trim($vMatches[1]);
  } // fi
  return $vVersion;
 }

/** comment */
 function getLatestVersion() {
  return $this->getVersion($this->mDownloadURL,FALSE);
 }

/** get the current I'm currently use */
 function getMyVersion() {
  return $this->getVersion($this->mTmpFileName,TRUE);
 }

/** if need to update */
 function checkUpdate() {
  $vMy = $this->getMyVersion();
  $vLatest = $this->getLatestVersion();
  if (!file_exists($this->mTmpFileName) || $vMy<$vLatest) { // should update
   $vContent = file_get_contents($this->mDownloadURL);
   file_put_contents($this->mTmpFileName,$vContent);
   return 'Updated to version #'.$vLatest.' from #'.$vMy; // yes, do update
  } // fi

return 'Already at the latest version #'.$vLatest; // latest, don't update
 }

/** fix the browsecap.ini for php */
 function fix() {
  $vOutput = $this->checkUpdate();

$vContent = file_get_contents($this->mTmpFileName);
  $vContent = preg_replace("/\r/","",$vContent);
  $vContent = preg_replace('/="(.*)"/i','=\\1',$vContent);
  $vContent = preg_replace("/platform=(.*)/i","platform=\"\\1\"",$vContent);
  $vContent = preg_replace("/parent=(.*)/i","parent=\"\\1\"",$vContent);
  $vContent = preg_replace("/minorver=(.*)/i","minorver=\"\\1\"",$vContent);
  $vContent = preg_replace("/majorver=(.*)/i","majorver=\"\\1\"",$vContent);
  $vContent = preg_replace("/version=(.*)/i","version=\"\\1\"",$vContent);
  $vContent = preg_replace("/browser=(.*)/i","browser=\"\\1\"",$vContent);
  $vContent = str_replace("[*]","*",$vContent);
  file_put_contents('browscap.ini',$vContent);

return $vOutput;
 }
}
?>

Simple & fast spider detection

Developers can use the browscap.ini to detect if the User-Agent is a search engine or data collection spider or not. However, that file is rather large and will be expensive on resources. If you need a faster, simpler (albeit less accurate) method, this class can be useful.

<?php
/** a quick/less resource intensive browser detection
* @author Son Nguyen
* @since 1/29/2007
* @package Framework
* @subpackage Misc
*/
class CBrowserDetect {
 private $mUA;
 /** constructor */
 function __construct($pUA=NULL) {
  $this->setUA($pUA);
 }

/** comment */
 function setUA($pUA=NULL) {
  if (is_null($pUA) && isset($_SERVER['HTTP_USER_AGENT'])) {
   $this->mUA = $_SERVER['HTTP_USER_AGENT'];
  } else {
   $this->mUA = $pUA;
  } // fi
 }

/** if this is a spider/crawler */
 function isSpider($pUA=NULL) {
  $this->setUA($pUA);
  $vBots = array( 
   'AdsBot-Google',
   'alexa',
   'appie',
   'Ask Jeeves',
   'Baiduspider',
   'crawler',
   'FAST',
   'Firefly',
   'froogle',
   'girafabot',
   'Googlebot',
   'ia_archiver',
   'InfoSeek',
   'inktomi',
   'Java/',
   'looksmart',
   'msnbot',
   'NationalDirectory',
   'rabaz',
   'Scooter',
   'Slurp',
   'Spade',
   'TECNOSEEK',
   'Teoma',
   'URL_Spider_SQL',
   'WebBug',
   'WebCapture',
   'WebFindBot',
   'Wget/',
   'ZyBorg',
   'libwww-perl/',
   'httpunit/',
   'WebZIP/',
  );
  foreach ($vBots AS $vPat) {
   if (stripos($this->mUA,$vPat)!==FALSE) {
    return TRUE;
   } // fi
  } // rof
  return FALSE;
 }
}
?>
