<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).
