如何从SQL db中正确获取blob（MAX）图像

Question

When i try to get a image as blob i get this response: The Response content must be a string or object implementing __toString(), "boolean" given.

my code is as following, The GET query

function GET_shopimages($shopid){
    $currentUserName = Auth::user()->name;
    $query = "SELECT * FROM srms_dam.dbo.pictures WHERE srms_dam.dbo.pictures.shopid = (?) ";
    $parameters = array((int) $shopid);
    return executeImageObjectQuery($query, $parameters);
}

the executeImageObjectQuery:

 function executeImageObjectQuery($inputQuery, $stagingParameters){
        $conn = buildConnection();
        if( $conn ) {
            $query = $inputQuery;
            $result = sqlsrv_query($conn, $query, $stagingParameters);
            $detailresult  = sqlsrv_fetch_array($result); echo '<img 
            src="data:image/jpeg;base64,'.base64_encode( $result['picture'] ).'"/>';
            sqlsrv_close ($conn);
            return $detailresult;
      } else {
         return response('Cannot build database connection', 503);
    }
}

I already looked at the different questions surrounding blob but could not find an answer, any help would be greatly appreciated. the Query worked in the database itself. $detailresult = $result here.

(if i need to insert my routing code please let me know)

Since this took to long to figure out i decided to just upload the picture path in the db and go from there. Question still remains though because i'm sure i am not the only one having this issue

Answer 1

There is probably a typo error:

$result['picture']

You fetch results into $detailresult and you should use it:

$detailresult['picture']

Still, you may get some errors from your sql query, therefore I would use sqlsrv_errors .
