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

    説明

    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.

    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

    <?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);
    ?>
