PHP and Postgres: catching errors?

Question

How should I prepare the code if it something fails? With try-catch statement or?

function delete_question ( $question_id ) {
    $dbconn =          


        

Answer 1

I have another practice

$result = pg_query_params ( $dbconn,'DELETE FROM questions WHERE question_id = $1', array ( $question_id ) )
          or die(pg_last_error($dbconn));
