Sends an ALLO command to the remote FTP server to
allocate space for a file to be uploaded.
Note:
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.
Parameters
ftp_stream
The link identifier of the FTP connection.
filezise
The number of bytes to allocate.
return
A textual representation of the servers response will be returned by
reference in result if a variable is provided.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example 1. ftp_alloc() example
<?php
$file = "/home/user/myfile";
/* connect to the server */ $conn_id = ftp_connect('ftp.example.com'); $login_result = ftp_login($conn_id, 'anonymous', 'user@example.com');
if (ftp_alloc($conn_id, filesize($file), $result)) { echo "Space successfully allocated on server. Sending $file.\n"; ftp_put($conn_id, '/incomming/myfile', $file, FTP_BINARY); } else { echo "Unable to allocate space on server. Server said: $result\n"; }
