PHP get image from byte[] out of a Database

Question

I want to display an Image with a PHP-Script. I get the image data out of a Database. The data is a byte[]. Does anyone know how to do this?

I tried this yet:

function GetImage($imageDataArray)
{
   $base64String = "";
   for($i = 0; $i < count($imageDataArray); $i++)
   {
       $string = trim(strtr(base64_encode($imageDataArray[$i]), '+/', '-_'), '='); 
       $base64String .= $string;
   }

   return 'data:image/png;base64,' . $base64String ;
}

And call it here:

echo '<img src="'.$im->GetImage($imageDataArray).'" alt="Picture" />';

But I don't get an result. The picture is not shown.

have a look on following [base64 encoded images][1] [1]: http://stackoverflow.com/questions/3259967/sending-displaying-a-base64-encoded-image — Muhammad Ummar, Jun 05 '12 at 11:46
are you setting content-type header to image/png? like `header("Content-Type: image/png");` — Muhammad Ummar, Jun 05 '12 at 12:06

get rid of base64_encode() && use urlencode() || rawurlencode()

@Ummar: I think with urlencode() it doesn't run. I think, the base64_encode() is wrong, because I get a String like this: _data:image/png;base64,MTM3ODANzgNzEMTMMTAMjYMTAMAMAMAMTMNzMNzINjgODIMAMAMAMTI4MAMAMAMTI4OANgMAMAMAMTk1NjIOTcM..._ I tried the same in ASP.NET MVC. I didn't have any problems there and the base64 string is different. – der_chirurg Jun 05 '12 at 12:28
