Use Akismet in php to prevent spam comments

Php uses Akismet to prevent spam comments. However, no one is perfect, and no plug (pieces) is complete! Akismet is not perfect either. Recently, I often find a "good guy" message in the comment that Akismet judges as spam. However, it is deleted automatically after a long time, loss of valuable friendship and messages.
Do not forget to modify _ YOUR_AKISMET_KEY __, _ YOUR_WEBSITE_URL _ and _ YOUR_NAME _ in the code __

Index. php
The code is as follows:
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 .'
