}

function get_height($mages) {
    list($img_width, $img_height) = getimagesize($mages);
    return $img_height;
}

function get_ratio($mages) {
    list($img_width, $img_height) = getimagesize($mages);
    return $img_width / $img_height;

    $image_height = imagesy($old_image);
    $image_aspect_ratio = $image_width / $image_height;
    $image_type = get_type($img);
    $image_mime = get_mime($img);

    $new_image = imagecreatetruecolor($width, $height);
    imagecopyresampled($new_image, $old_image, 0, 0, 0, 0, $width, $height, $image_width, $image_height);
    if(file_exists('resized-imges/sample2.jpg'))
        unlink('resized-imges/sample2.jpg');
    imagejpeg($new_image, 'resized-imges/sample2.jpg', 100);
