  <para>
   <function>sqlite_array_query</function> executes the given query and returns
   an array of the entire result set.  It is similar to calling <function>
   sqlite_query</function> and then <function>sqlite_fetch_array</function>
   for each row in the result set.  <function>sqlite_array_query</function> is
   significantly faster than the aforementioned.
  </para>
  <tip>
   <para>
    <function>sqlite_array_query</function> is best suited to queries
    returning 45 rows or less.  If you have more data than that, it is
    recommended that you write your scripts to use
    <function>sqlite_unbuffered_query</function> instead for more optimal
    performance.
