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

Try this:

echo '<img src="data:image/png;base64,' . $base64encodedString . '" />

Answer 2

If you are dealing with data stored in a PostgreSQL database bytea field you will receive a stream when fetching the PDO. To process the data any further first transform the stream to usual data like this: $stream = $row['content']; rewind($stream); $data=stream_get_contents($stream);

Answer 3

The solution to your problem is here:

How to decode a base64 string (gif) into image in PHP / HTML

Quoting that source but modifying:

In the case you strip out the first case and choose to decode the string, you should add this before echoing the decoded image data:

header("Content-type: image/gif");
$data = "/9j/4AAQSkZJRgABAQEAYABgAAD........";
echo base64_decode($data);

In the second case, use this instead:

echo '<img src="data:image/gif;base64,' . $data . '" />';

The second case is bad because the browser does not perform caching if the same image is shown on multiple pages.

Answer 4

Use this:

$code_base64 = $row['content'];
$code_base64 = str_replace('data:image/jpeg;base64,','',$code_base64);
$code_binary = base64_decode($code_base64);
$image= imagecreatefromstring($code_binary);
header('Content-Type: image/jpeg');
imagejpeg($image);
imagedestroy($image);

Answer 5

try this

//your image data

$logodata = "/9j/4AAQSkZJRgABAQEAYABgAAD........";
echo '<img src="data:image/gif;base64,' . $logodata . '" />';

/**
* @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;
 }
