Your not checking for error, try this: if($stmt->execute()) { //code } else{ die($stmt->error); } or: if($stmt = $this->conn->prepare($query)){ //code } else{ die($this->conn->error); }.
PDO's prepared statements work in effectively the same way. In your case, however, PDO is a bit stupid, because it's running in "emulate prepares" mode (which is the default, but you should turn it off to get the most from PDO). It basically does all the substitution itself, rather than sending the query and the data to the server separately.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
