Went through some info (also see: https://stackoverflow.com/a/13253440/165330 ).

It can but SHOULD NOT be done.

A way to do it, would use dynamic variables to provide auto-referencable variables and using call_user_func_array to supply a dynamic amount of arguments to the callback/method $stmt->bind_param() .

prepare('SELECT value1, value2 FROM table1 WHERE value3 IN (' . $s . ')');
# OR array_map in case of different datatypes
$typeDefintions = str_repeat( 's' , count( $values ) );
$params = array( $typeDefinitions );
foreach ( $values as $k => $v ) {
    ${ 'varvar' . $k } = $v;
    $params[] = &${ 'varvar' . $k };# provide references
}
call_user_func_array( array( $stmt , 'bind_param' ) , $params );
