dbase_create

(PHP 5 < 5.3.0, dbase 5, dbase 7)

dbase_createCreates a database

说明

dbase_create ( string $filename , array $fields [, int $type = DBASE_TYPE_DBASE ] ) : resource

dbase_create() creates a dBase database with the given definition. If the file already exists, it is not truncated. dbase_pack() can be called to force truncation.

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.

fields

An array of arrays, each array describing the format of one field of the database. Each field consists of a name, a character indicating the field type, and optionally, a length, a precision and a nullable flag. The supported field types are listed in the introduction section.

Note:

The fieldnames are limited in length and must not exceed 10 chars.

type

The type of database to be created. Either DBASE_TYPE_DBASE or DBASE_TYPE_FOXPRO.

返回值

Returns a database link identifier if the database is successfully created, or FALSE if an error occurred.
