ftp_alloc

(PHP 5, PHP 7, PHP 8)

ftp_allocAllocates space for a file to be uploaded

Опис

ftp_alloc(FTP\Connection $ftp, int $size, string &$response = null): bool

Sends an ALLO command to the remote FTP server to allocate space for a file to be uploaded.

Зауваження:

Many FTP servers do not support this command. These servers may return a failure code (false) indicating the command is not supported or a success code (true) to indicate that pre-allocation is not necessary and the client should continue as though the operation were successful. Because of this, it may be best to reserve this function for servers which explicitly require preallocation.
