How can I make .htaccess display errors from a PHP file? I mean when I search a non-existing file .htaccess should show me an error page from error.php, but error.php needs

You're looking for ErrorDocument.

In your .htaccess specify the codes you want to handle, like:

ErrorDocument 403 /error.php
ErrorDocument 404 /error.php
ErrorDocument 500 /error.php

And in error.php, handle the error codes like:

 'Forbidden',
        404 => 'Not Found',
        500 => 'Internal Server Error'
    );
    $source_url = 'http'.((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 's' : '').'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
    if (array_key_exists($code, $codes) && is_numeric($code)) {
        die("Error $code: {$codes[$code]}");
    } else {
        die('Unknown error');
    }
?>
