ibase_backup

(PHP 5, PHP 7 < 7.4.0)

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.

示例

<?php

// Attach to database server by ip address and port
$service = ibase_service_attach ('10.1.11.200/3050', 'sysdba', 'masterkey');

// Start the backup process on database server
// Backup employee database using full path to /srv/backup/employees.fbk
// Don't use any special arguments

// Free the attached connection
ibase_service_detach ($service);
?>

示例 #2 ibase_backup() example with arguments

// Backup only the metadata. Don't create a transportable backup.
ibase_backup($service, 'employees.fdb', '/srv/backup/employees.fbk', IBASE_BKP_METADATA_ONLY | IBASE_BKP_NON_TRANSPORTABLE);

I tried to get the backup function working, but could never figur out where to get the resource service_handle. The trick was to use ibase_service_attach.

$resource_service_handle = ibase_service_attach ('localhost', 'username', 'password');

ibase_backup($resource_service_handle, 'source_database', 'destination_file');

ibase_service_detach ($resource_service_handle);
