<span class="function"><strong>fbsql_fetch_object()</strong></span> is similar to
<span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span>, 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).
</p>
<p class="para">
Speed-wise, the function is identical to
<span class="function"><a href="fbsql_fetch_array.html" class="function">fbsql_fetch_array()</a></span>, and almost as quick as
<span class="function"><a href="fbsql_fetch_row.html" class="function">fbsql_fetch_row()</a></span> (the difference is
insignificant).
