<title>Performance</title>
<para>
Speed-wise, the function is identical to
<function>mysql_fetch_array</function>, and almost as quick as
<function>mysql_fetch_row</function> (the difference is
insignificant).
</para>
</note>
<note>
<para>
<function>mysql_fetch_object</function> is similar to
<function>mysql_fetch_array</function>, with one difference - an
object is returned, instead of an array. Indirectly, that means
that you can only access the data by the field names, and not by
their offsets (numbers are illegal property names).
