title: what to do on PHP PDO execute() returns false?
body: <p>The php manual (<a href="http://www.php.net/manual/en/pdostatement.execute.php" rel="nofollow">http://www.php.net/manual/en/pdostatement.execute.php</a>) mentions at Return Values: "Returns TRUE on success or FALSE on failure."</p>
  
  <p>I'm writing a php script with several PDO::execute statements. What should be done when PHP:PDO would indeed return FALSE? Stop the entire script (call exit()) or continue or something else? What are possible reasons for Execute() returning false? Or is returning false only a very theoretical scenario that almost never happens in reel live?</p>
