class BlogController{

    public function search($txtsearch){
        $mysqli = new mysqli("localhost","root","","sample_db");

        $display_query = "SELECT * FROM `tb_blogs` WHERE id='$txtsearch' ";
        $result = $mysqli->query($display_query);
    }

}

     if(isset($_POST["btnsearch"])){
        echo BlogController::search();
    }  
?>

嘗試這個：

class BlogController{

        public $txtsearch;

        function __construct($search) {
            $this->$txtsearch  = $search;
       }

        public function search(){
            $mysqli = new mysqli("localhost","root","","sample_db");

            $display_query = "SELECT * FROM `tb_blogs` WHERE id='$this->$txtsearch' ";
            $result = $mysqli->query($display_query);
            return $result;
        }

}

創建一個實例，然后調用函數搜索

$myclass = new BlogController($_POST['txtsearch']); //pass value to the construct function
print_r($myclass->search());  // will return an array
