fbsql_db_status()

(PHP 4 >= 4.0.7, PHP 5, PHP 7)

Get the status for a given database

说明

fbsql_db_status(string $database_name[,resource $link_identifier]): int

Gets the current status of the specified database.

$database_name

The database name.

$link_identifier

由fbsql_connect()或fbsql_pconnect()返回的 FrontBase 链接标识符.

如可选并未指定，函数会尝试查找一个到 FrontBase 服务器的开放链接，且如没有找到这样的链接，会尝试通过不带参数调用fbsql_connect()来创建一个。

Returns an integer value with the current status. This can be one of the following constants:

FALSE- The exec handler for the host was invalid. This error will occur when the$link_identifierconnects directly to a database by using a port number. FBExec can be available on the server but no connection has been made for it.
FBSQL_UNKNOWN- The Status is unknown.
FBSQL_STOPPED- The database is not running. Use fbsql_start_db() to start the database.
FBSQL_STARTING- The database is starting.
FBSQL_RUNNING- The database is running and can be used to perform SQL operations.
FBSQL_STOPPING- The database is stopping.
FBSQL_NOEXEC- FBExec is not running on the server and it is not possible to get the status of the database.
