Add error 404 friendly url

Question

Good

I am making the routes of the urls friendly by the htacess file and now I wanted to show the error 404 if the user type a name that does not exist.

But I don’t know how I can do it

I have the code that presents the contents like this

if(!isset($_REQUEST['controller']) || empty($_REQUEST['controller'])){
       require_once("conteudos/home.php");
        }else{
            require_once("conteudos/".$_GET['controller'].".php");
        }

Answer 1

In php with the function curl_init();

$handle = curl_init($url);
curl_setopt($handle,  CURLOPT_RETURNTRANSFER, TRUE);

/* Obtendo o arquivo que está conectado a $url. */
$response = curl_exec($handle);

/* Checando se há erro 404 (Arquivo não existe). */
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
if($httpCode == 404) {
    /* Aqui está a resposta do erro 404. */
}

curl_close($handle);

  /* $response aqui. */

if (($this->error->getCode()) == '404') {
  header('Location: /index.php?option=com_content&view=article&id=75');

                    <p><?php _e( 'It looks like nothing was found at this location. Maybe try a search?', 'twentythirteen' ); ?></p>

                    <?php get_search_form(); ?>
