Execute the prepared statement. If the prepared statement included
parameter markers, you must either:

<listitem><para>call <function>PDOStatement::bindParam</function> to bind PHP variables
to the parameter markers: bound variables pass their value as input and receive the
output value, if any, of their associated parameter markers</para></listitem>
