px_open_fp — Open paradox database

### 说明

px_open_fp ( resource `$pxdoc` , resource `$file` ) : bool

Open an existing paradox database file. The actual file has to be opened before with fopen(). This function can also be used to open primary index files and tread them like a paradox database. This is supported for those who would like to investigate a primary index. It cannot be used to accelerate access to a database file.

### 参数

`pxdoc`

  Resource identifier of the paradox database as returned by px_new().

`file`

  `file` is the return value from fopen() with the actual database file as parameter. Make sure the database is writable if you plan to update or insert records.

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。
