PHP マニュアル: Initiates a backup task in the service manager and returns immediately

説明

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

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

パラメータ

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 定義済み定数 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.

戻り値

成功した場合に true を、失敗した場合に false を返します。

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.

例

例1 ibase_backup example

<?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
ibase_backup($service, '/srv/firebird/employees.fdb', '/srv/backup/employees.fbk');

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

例2 ibase_backup example with arguments

<?php

// Attach to database server by name and default port
$service = ibase_service_attach ('fb-server.contoso.local', 'sysdba', 'masterkey');

// Start the backup process on database server
// Backup employee database using alias to /srv/backup/employees.fbk.
// 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);

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