Please note, that contents of LOB is cleared after this operation. If you want to use LOB data after exporting it to file, you should read it from file with file_get_contents().

This will not work:
<?php
if($blob) {
   
$filename = DOCUMENT_ROOT."/".$bildId.".jpg";
    if(
$blob->export($filename)) {
        while(!
$blob->eof()){
           
$dbResult .= $blob->read(2000);
        }
    } else {
        throw new
Exception("Can not save the file ".$filename."!");
    }
}
?>

Use this instead:
<?php
if($blob) {
   
$filename = DOCUMENT_ROOT."/".$bildId.".jpg";
    if(
$blob->export($filename)) {
       
$dbResult = file_get_contents($filename);
    } else {
        throw new
Exception("Can not save the file ".$filename."!");
    }
}
?>
