dbase_open()
(PHP 5 < 5.3.0, dbase 5, dbase 7)
Opens a database
说明
dbase_open(string $filename,int $mode): resource
dbase_open() opens a dBase database with the given access mode.
Note:当启用安全模式时,PHP 会检查被操作的文件或目录是否与被执行的脚本有相同的 UID(所有者)。
Note:
此函数受open_basedir影响。
参数
- $filename
The name of the database. It can be a relative or absolute path to the file where dBase will store your data.
- $mode
An integer which correspond to those for the open() system call(Typically 0 means read-only, 1 means write-only, and 2 means read and write).
Note:
You can't open a dBase file in write-only mode as the function will fail to read the headers information and thus you can't use 1 as$mode.
As of dbase 7.0.0 you can use
DBASE_RDONLY
andDBASE_RDWR
, respectively, to specify the$mode.

If you are wanting to open Foxpro tables using this, make sure they are in the 2.x format or php will not respond. In VFP use the following: COPY TO tablename.dbf TYPE FOX2X This is an easy way to bring database info to the web if you have a small foxpro setup.
COPY TO tablename.dbf TYPE FOXPLUS The table is exported like DBase IV version and works fine with php.
