php中使用Akismet防止垃圾评论的代码_PHP

然而，人无完人，插（件）无完插！Akismet也并非完美，最近， 我常在被Akismet评判为垃圾的留言中找到“好人”的留言，然而，有时时间长了就自动删除了，损失珍贵的友情和留言。
别忘了修改代码中的 __YOUR_AKISMET_KEY__, __YOUR_WEBSITE_URL__ and __YOUR_NAME__

index.php
代码如下:

require_once ('classes/Akismet.class.php'); 
class MySpamProtection { 
// variables 
var $sMyAkismetKey; 
var $sWebsiteUrl; 
var $sAuthName; 
var $sAuthEml; 
var $sAuthUrl; 
var $oAkismet; 
// constructor 
public function MySpamProtection() { 
// set necessary values for variables 
$this->sMyAkismetKey = '__YOUR_AKISMET_KEY__'; 
$this->sWebsiteUrl = '__YOUR_WEBSITE_URL__'; 
$this->sAuthName = '__YOUR_NAME__'; 
$this->sAuthEml = ''; 
$this->sAuthUrl = ''; 
// Akismet initialization 
$this->oAkismet = new Akismet($this->sWebsiteUrl ,$this->sMyAkismetKey); 
$this->oAkismet->setCommentAuthor($this->sAuthName); 
$this->oAkismet->setCommentAuthorEmail($this->sAuthEml); 
$this->oAkismet->setCommentAuthorURL($this->sAuthUrl); 
} 
public function isSpam($s) { 
if (! $this->oAkismet) return false; 
$this->oAkismet->setCommentContent($s); 
return $this->oAkismet->isCommentSpam(); 
} 
} 
echo << 
 
EOF; 
if ($_POST) { 
// draw debug information 
echo '
'; 
print_r($_POST); 
echo '
'; 
// obtain sent info 
$sPostAuthor = $_POST['author']; 
$sCommentComment = $_POST['comment']; 
// check for spam 
$oMySpamProtection = new MySpamProtection(); 
$sAuthorCheck = ($oMySpamProtection->isSpam($sPostAuthor)) ? ' "Author" marked as Spam' : '"Author" not marked as Spam'; 
$sCommentCheck = ($oMySpamProtection->isSpam($sCommentComment)) ? ' "Comment" marked as Spam' : '"Comment" not marked as Spam'; 
echo $sAuthorCheck . '
' . $sCommentCheck; 
} 
?>
