Displaying a Base64 images from a database via PHP

Question

I have this database that contains images as strings. Those strings look something like this:

data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABgAAD...
         


        

Answer 1

/**
* @param $base64_image_content 
* @param $path 
* @return bool|string
*/
function base64_image_content($base64_image_content,$path){
  if (preg_match('/^(data:\s*image\/(\w+);base64,)/', $base64_image_content, $result)){
    $type = $result[2];
    $new_file = $path."/".date('Ymd',time())."/";
    $basePutUrl = C('UPLOAD_IMG_BASE64_URL').$new_file;

    if(!file_exists($basePutUrl)){
        //Check if there is a folder, if not, create it and grant the highest authority.
       mkdir($basePutUrl, 0700);
    }
       $ping_url = genRandomString(8).time().".{$type}";
       $ftp_image_upload_url = $new_file.$ping_url;
       $local_file_url = $basePutUrl.$ping_url;

   if (file_put_contents($local_file_url, base64_decode(str_replace($result[1], '', $base64_image_content)))){
     ftp_upload(C('REMOTE_ROOT').$ftp_image_upload_url,$local_file_url);
         return $ftp_image_upload_url;
    }else{
         return false;
    }
  }else{
     return false;
 }
}
