2 - Indigestion for Spam Bots

How about doing the complete opposite of last month's article? This time we generate (random) email addresses every time a page is loaded specifically for the spam bots in order to fill up their databases with rubbish addresses - rendering their mailing lists worthless for reselling. Here's an example list...

elspeth howard Charlie Bob Charlie Dave francis Judith howard elspeth Ian elspeth elspeth Alice Judith Judith francis gary Charlie Bob

And here's the php code that generated it. Feel free to incorporate it into your site changing the arrays of names, companies and TLDs (top level domains).

		$EmailCount = 20 ;

		$AName = array ('Alice','Bob','Charlie','Dave','elspeth', ->
  'francis','gary','howard','Ian','Judith') ;

		$ACompany = array ('technology','photo','sales','bedding','intercom','widget', -> 
  'flower','board','fish','copy') ;

		$ATLD = array ('net','eu','org','biz','com','co.fr','co.de', -> 
  'gov.uk','co.jp','ng') ;

		$Extras = "1234567890abcdefghijklmnopqrstuvwxyz" ;

		for ($i=0; $i<$EmailCount; $i++ )

		  {

		  $Name = $AName[rand(0,9)] ;

		  $Company = $ACompany[rand(0,9)] ;

		  $ExtraLength = rand(5,7) ;

		  for ($c=0 ; $c<$ExtraLength ; $c++)

		    $Company .= substr($Extras,rand(0,35),1) ;

		  $TLD = $ATLD[rand(0,9)] ;

		  echo '<a href="mailto:'.$Name.'@'.$Company.'.'.$TLD. -> 
    '">'.$Name.'</a> '."\n" ;

		  }

Note: -> at the end of a line indicates that the code is continued on the following line.
