ftp_pasv

    (PHP 4, PHP 5, PHP 7, PHP 8)

    ftp_pasv — Turns passive mode on or off

    Description

    ftp_pasv(FTP\Connection$ftp, bool$enable): bool

    ftp_pasv() turns on or off passive mode. In passive mode, data connections are initiated by the client, rather than by the server. It may be needed if the client is behind firewall.

    Please note that ftp_pasv() can only be called after a successful login or otherwise it will fail.

    Parameters

    ftp

    An FTP\Connection instance.

    enable

    If true, the passive mode is turned on, else it's turned off.

    Return Values

    Returns true on success or false on failure.

    Changelog

    VersionDescription
    8.1.0 The ftp parameter expects an FTP\Connection instance now; previously, a resource was expected.
