<span class="function"><strong>msql_fetch_object()</strong></span> is similar to
|
|
<span class="function"><a href="msql_fetch_array.html" class="function">msql_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).

Speed-wise, the function is identical to

<span class="function"><a href="msql_fetch_array.html" class="function">msql_fetch_array()</a></span>, and almost as quick as
|
|
<span class="function"><a href="msql_fetch_row.html" class="function">msql_fetch_row()</a></span> (the difference is
|
|
insignificant).
