<function>mysql_free_result</function> only needs to be called if
|
|
you are concerned about how much memory is being used for queries
|
|
that return large result sets. All associated result memory is
|
|
automatically freed at the end of the script's execution.

If a non-resource is used for the <parameter>result</parameter>, an
|
|
error of level E_WARNING will be emitted. It's worth noting that
|
|
<function>mysql_query</function> only returns a <type>resource</type>
|
|
for SELECT, SHOW, EXPLAIN, and DESCRIBE queries.
