Images are not displayed after site migration, what could be the reason?

Question

PHP

On the old hosting, everything is arranged like this.
there are two sites. two folders .. one site.ru and the second m.site.ru.
On the mobile version of the site, when images are displayed, it happens with the help of htaccess - resize images, which are located in the site.ru folder.

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^files/products/(.+) resize/resize.php?file=$1&token=%{QUERY_STRING}

resize.php file

$filename = $_GET['file'];
$token = $_GET['token'];
$resized_filename =  $simpla->image->resize($filename);

if(is_readable($resized_filename)) /* Возвращает true */ 
{
  header('Content-type: image');
  print file_get_contents($resized_filename);

}

The resize function itself

function resize($filename)
  {
    list($source_file, $width , $height, $set_watermark) = $this->get_resize_params($filename);


    // Если вайл удаленный (http://), зальем его себе
    if(substr($source_file, 0, 7) == 'http://')
    {	
      // Имя оригинального файла
      if(!$original_file = $this->download_image($source_file))
        return false;
      
      $resized_file = $this->add_resize_params($original_file, $width, $height, $set_watermark);			
    }	
    else
    {
      $original_file = $source_file;
    }
    
    $resized_file = $this->add_resize_params($original_file, $width, $height, $set_watermark);			
    
  
    // Пути к папкам с картинками
    $main_site_root_dir = "/var/www/vhosts/site.ru/httpdocs/";
    /*$originals_dir = $this->config->root_dir.$this->config->original_images_dir;
    $preview_dir = $this->config->root_dir.$this->config->resized_images_dir;*/
    $originals_dir = $main_site_root_dir.$this->config->original_images_dir;

    $preview_dir = $main_site_root_dir.$this->config->resized_images_dir;
    
    $watermark_offet_x = $this->settings->watermark_offset_x;
    $watermark_offet_y = $this->settings->watermark_offset_y;
    
    $sharpen = min(100, $this->settings->images_sharpen)/100;
    $watermark_transparency =  1-min(100, $this->settings->watermark_transparency)/100;
  
  
    if($set_watermark && is_file($this->config->root_dir.$this->config->watermark_file))
      $watermark = $this->config->root_dir.$this->config->watermark_file;
    else
      $watermark = null;

    if(class_exists('Imagick') && $this->config->use_imagick)
      $this->image_constrain_imagick($originals_dir.$original_file, $preview_dir.$resized_file, $width, $height, $watermark, $watermark_offet_x, $watermark_offet_y, $watermark_transparency, $sharpen);
    else
      $this->image_constrain_gd($originals_dir.$original_file, $preview_dir.$resized_file, $width, $height, $watermark, $watermark_offet_x, $watermark_offet_y, $watermark_transparency);
    return $preview_dir.$resized_file;
  }

On the new hosting, it doesn't want to show pictures.. I saw some strange errors in the logs, I couldn't make them out..

Answer 1

There, non-displayed images have some non-displayed characters at the beginning of the url that confuse everyone.
EF BB BF 68 74 74

Answer 2

EF BB BF - это сигнатура BOM

Answer 3

Всем спасибо. Действительно все дело было из этих символов, BOM, пересохранил файл в кодировке UTF без bom и все заработало
