Answer 1

Do you REALLY wants to insert BINARY data in your database? Trust me, you won't. You just have to save the path to the file!

If you really want to save it, transform your image in base64 then write it in your database.

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
