PHP ftp_alloc() Function

The ftp_alloc() function is used to allocate space for a file to be uploaded to the FTP server.ftp_alloc — Allocates space for a file to be uploaded.

bool ftp_alloc ( resource $ftp_stream , int $filesize [, string &$result ] )

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

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.
