ftp_alloc — Allocates space for a file to be uploaded
$ftp_stream
, int $filesize
[, string &$result
] )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.
ftp_stream
The link identifier of the FTP connection.
filesize
The number of bytes to allocate.
result
A textual representation of the servers response will be returned by
reference in result if a variable is provided.
Returns TRUE on success or FALSE on failure.
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', '[email protected]');
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: $result\n";
}
ftp_close($conn_id);
?>
