警告
這個函數是實驗性質的。這個函數的行為、名稱、和關於此函數的任何其他文件在未來PHP的發行中可能會在不通知的情況下改變。 使用此延伸需自行承擔風險。

The relation file name will be opened. name can be either a file name or a relative or absolute path name. This will be mapped in any case to an absolute relation file path on a specific host machine and server.

On success a relation file resource (cursor) is returned which must be used in any subsequent commands referencing the relation. Failure leads to a zero return value, the actual error code may be asked for by calling dbplus_errno().
