ibase_backup — Initiates a backup task in the service manager and returns immediately

说明

ibase_backup ( resource $service_handle , string $source_db , string $dest_file [, int $options = 0 [, bool $verbose = false ]] ) : mixed

This function passes the arguments to the (remote) database server. There it starts a new backup process. Therefore you won't get any responses.

参数

service_handle

A previously opened connection to the database server.

source_db

The absolute file path to the database on the database server. You can also use a database alias.

dest_file

The path to the backup file on the database server.

options

Additional options to pass to the database server for backup. The options parameter can be a combination of the following constants: IBASE_BKP_IGNORE_CHECKSUMS, IBASE_BKP_IGNORE_LIMBO, IBASE_BKP_METADATA_ONLY, IBASE_BKP_NO_GARBAGE_COLLECT, IBASE_BKP_OLD_DESCRIPTIONS, IBASE_BKP_NON_TRANSPORTABLE or IBASE_BKP_CONVERT. Read the section about 预定义常量 for further information.

verbose

Since the backup process is done on the database server, you don't have any chance to get its output. This argument is useless.

返回值

成功时返回 true， 或者在失败时返回 false。

Since the backup process is done on the (remote) server, this function just passes the arguments to it. While the arguments are legal, you won't get false.
