file_exists() not working codeigniter

I am working with codeigniter. I want to display images but if some image is not exist it should show image-not-found-medium.jpg which is dummy image..

below is my code

<?php
    $image_path_medium = site_url('assets/images-products/medium');
    $image_not_found_medium =  $image_path_medium . "/" . "image-not-found-medium.jpg";
    $image_name_with_path = $image_path_medium . "/" . $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg";

    if (file_exists($image_name_with_path)) {
        echo $image_name_with_path;
    } else {
        echo $image_not_found_medium;
    }
    ?>

but it always shows $image_not_found_medium i think there is problem with my if condition. Please help.

Use like this.

$g = base_url().'upload/image.jpg';
if(file_exists($g) !== null){//your code..}

This is works for me in CI.

Instead of file_exists() prefer is_file() when checking files, as file_exists() returns true on directories. In addition, you might want to see if getimagesize() returns FALSE to make sure you have an image.

You are using absolute path for file existence which is wrong. You have to use real path because the file_exists() function checks whether or not a file or directory exists on the current server.

If your assets folder is placed in root then just use getcwd() - Gets the current working directory as

$image_path_medium = getcwd().'assets/images-products/medium';

Otherwise give the proper path to the assets folder like

$image_path_medium = getcwd().'application/views/assets/images-products/medium';

    $image_name_with_path = $image_path_medium . "/" . $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg";//this is your image url
    $image_file_path=FCPATH.'assets/images-products/medium'. $home_technology[$key]->product_sku . "-" . "a" . "-medium.jpg";//this is your file path

   if (file_exists($image_file_path)) //file_exists of a url returns false.It should be real file path
   {
       echo $image_name_with_path;
   } 
   else 
   {
      echo $image_not_found_medium;
   }
?>
