$query = "SELECT 'No more you-know-what-I-mean for lunch, please' AS _msg FROM DUAL" ;
$ret = parent :: prepare ( $res , $query );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
var_dump ( $ret );
return $ret ;
}
}
mysqlnd_uh_set_statement_proxy (new stmt_proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
$stmt = $mysqli -> prepare ( "SELECT 'Labskaus' AS _msg FROM DUAL" );
$stmt -> execute ();
$msg = NULL ;
$stmt -> bind_result ( $msg );
$stmt -> fetch ();
var_dump ( $msg );
?>
以上例程会输出:
stmt_proxy::prepare(array ( 0 => NULL, 1 => 'SELECT \'Labskaus\' AS _msg FROM DUAL', )) stmt_proxy::prepare returns true bool(true) string(46) "No more you-know-what-I-mean for lunch, please"
