Retrieves a result set from a prepared statement as a
<classname>mysqli_result</classname> object. The data will be fetched from
the MySQL server to PHP. This method should be called only for
queries which produce a result set.

Returns &false; on failure. For successful queries which produce a result set, such as <literal>SELECT, SHOW, DESCRIBE</literal> or

a <classname>mysqli_result</classname> object. For other successful queries, <function>mysqli_stmt_get_result</function> will
return &false;. The <function>mysqli_stmt_errno</function> function can be
used to distinguish between the two reasons for &false;; due to a bug, prior to PHP 7.4.13,
<function>mysqli_errno</function> had to be used for this purpose.
