PHP PDO simple insert or update function

Question

In trying to create a simple PHP PDO update function that if the field is not found would insert it, I created this little snippet.

function updateorcreate($         


        

Answer 1

You will first need to execute it.

Apart from that, this is a dodgy way of doing this. It would be better to start a transaction, do a SELECT and then determine what to do (INSERT or UPDATE). Just checking whether the UPDATE query succeeded doesn't suffice, it succeeds when no row is found too.
