PHP: Cannot redeclare class Comment::GetComment

Question

Can someone correct me my code? The error is " Fatal error: Cannot redeclare Comment::getComment() " if the error is in this file, can you show it to me or correct it? Otherwise tell me how I can fix this Thanks you.

<?php  
require_once(__DIR__.'/../model/article_model.php');
require_once(__DIR__.'/../model/comments_model.php');
require_once(__DIR__.'/../model/espaceadmin_model.php');

class CommentsController {

    public static function commentsPage () {
            if(isset($_POST['deletecomments'])) {
            $deletecomments= Comment::getComment((int) $_POST['post_id']);
            $deletecomments->deletecomment();
    }
        $template = file_get_contents(__DIR__.'/../view/backend/template-admin.html');
        $view = file_get_contents(__DIR__.'/../view/backend/commentsadmin_view.html');
        $loop_content = file_get_contents(__DIR__.'/../view/backend/commentsadmin_articles.html');
        $articles = Article::getArticles();


        $articleListe = "";
        foreach ($articles as $article) {
            $articleListe.=  str_replace('{ARTICLE_TITLE}', $article->getTitre(), $loop_content);
            $articleListe =  str_replace('{ARTICLE_DATE}', $article->getDate(), $articleListe);
            $articleListe =  str_replace('{ARTICLE_CONTENT}', $article->getContenu(), $articleListe);

            $comments = Comment::getComments($article->getId());
        foreach ($comments as $comment) {
            $articleListe =  str_replace('{COMMENTS_AUTHOR}', $comment->getAuthor(), $articleListe);
            $articleListe =  str_replace('{COMMENTS_DATE}', $comment->getComment_Date(), $articleListe);
            $articleListe =  str_replace('{COMMENTS_COMMENT}',$comment->getComment(), $articleListe);
            $articleListe = str_replace('{COMMENT_POSTID}', $comment->getPost_id(), $articleListe);
        }
        }

        $view = str_replace('{BOUCLE}', $articleListe, $view);
        $template = str_replace('{CONTENT}', $view, $template);
        $template = str_replace('{TITLE}', "Index", $template);

        print($template);
    }

}

CommentsController::commentsPage();

edit: here is the other file, how can I remove this error? I would like to keep both functions

<?php

overloading is not allowed in PHP. You can not have two functions with the same name and different arguments. Please have a look at this page: PHP two methods with the same name
