How to Display a BLOB Image from database?

Question

I know there are several questions on the same topic however none of them actually resolved my issue. I have tried approaches from the following questions:

• Not displaying a blob image
• Problems displaying blob images
• How to get a BLOB image from a mysql database displayed on your website using php
• PHP display image BLOB from MySQL [duplicate]

But every approach leads to the same result. I'm getting this sort of thing instead of the image: My code for database connection is same for insertion and I can successfully insert images its just they are not getting displayed. Still I'm pasting my codes in case they're relevant:

Connection String:

  $user = "root"; $pass = ""; $db = "raw_images"; $conn = mysqli_connect('localhost',$user,$pass,$db); if(!$conn) { die(mysqli_error()); } 

Display code:

 echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>'; 

Insert Code:

 <!--HTML Form--> <form action="" method="POST" enctype="multipart/form-data"> <input type="file" name="files[]" multiple class="Box"/> <input type="submit" class="Default"/> </form> <!--PHP Code--> $imageData = array(); if(isset($_FILES['files'])){ $errors= array(); foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){ $file_name = $key.$_FILES['files']['name'][$key]; $file_tmp =$_FILES['files']['tmp_name'][$key]; array_push($imageData, $file_name); $desired_dir="user_data"; if(empty($errors)==true){ if(is_dir($desired_dir)==false){ mkdir("$desired_dir", 0700); // Create directory if it does not exist } if(is_dir("$desired_dir/".$file_name)==false){ move_uploaded_file($file_tmp,"user_data/".$file_name); }else{ //rename the file if another one exist $new_dir="user_data/".$file_name.time(); rename($file_tmp,$new_dir) ; } }else{ print_r($errors); } if(empty($error)){ $imgDt = implode("|", $imageData); $query="INSERT INTO tbl_raw_image (image) VALUES('$imgDt'); "; $rs = mysqli_query($conn, $query); $imageData = array(); } } }

You forgot to take the right raw data. Note this line:

$blobimage = addslashes(file_get_contents($_FILES['files']['tmp_name'][$key]));


foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
        $blobimage = addslashes(file_get_contents($_FILES['files']['tmp_name'][$key]));
        $filename = $_FILES['files']['name'][$key];
        $path = $_FILES['files']['name'][$key];
        $ext = pathinfo($path, PATHINFO_EXTENSION);
        $desired_dir="upload/";
        if(empty($errors)==true){
            if(is_dir($desired_dir)==false){
                mkdir("$desired_dir", 0700);        // Create directory if it does not exist
            }
            if(is_dir("$desired_dir".$filename.'.'.$ext)==false){
                move_uploaded_file($_FILES['files']['tmp_name'][$key], $desired_dir.$filename.'.'.$ext);
            }else{          
                $new_dir=$desired_dir.$filename.'.'.$ext.time();
                rename($desired_dir.$filename.'.'.$ext,$new_dir) ;
            }            

        }else{
                print_r($errors);
        }

    if(empty($error)){
        $query="INSERT INTO tbl_raw_image (image) VALUES('$blobimage'); ";
        $rs  = mysqli_query($conn, $query);
    }
}
