   Execute the prepared statement. If the prepared statement included
   parameter markers, you must either:
   <itemizedlist>
    <listitem><para>call <function>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>
    <listitem><para>or pass an array of parameter values</para></listitem>
   </itemizedlist>
