mysql_free_result

Free result memory

&mysql.alternative.note;

- `mysqli_free_result`
- Assign the value of &null; to the PDO object, or `PDOStatement::closeCursor`

&reftitle.description; `bool` `mysql_free_result` `resource` `result`

`mysql_free_result` will free all memory associated with the result identifier `result`.

`mysql_free_result` 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.

&reftitle.parameters;

&mysql.result.description;
&reftitle.returnvalues;

&return.success;

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

### A `mysql_free_result` example

    <?php
    $result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
    if (!$result) {
        echo 'Could not run query: ' . mysql_error();
        exit;
    }
    /* Use the result, assuming we're done with it afterwards */
    $row = mysql_fetch_assoc($result);

    /* Now we free up the result and continue on with our script */
    mysql_free_result($result);

    echo $row['id'];
    echo $row['email'];
    ?>
