How to get the FTP error when using PHP

Question

I have a script which logs on to a remote server and tries to rename files, using PHP.

The code currently looks something like this example from the php.net website:

if (ftp_rename($conn_id, $old_file, $new_file)) {  echo "successfully renamed $old_file to $new_file\n"; } else {  echo "There was a problem while renaming $old_file to $new_file\n"; } 

but ... what was the error? Permissions, no such directory, disk full?

How can I get PHP to return the FTP error? Something like this:

echo "There was a problem while renaming $old_file to $new_file:  the server says $error_message\n"; 

Answer 1

You could use error_get_last() if return value is false.

Answer 2

I'm doing something like:

$trackErrors = ini_get('track_errors'); ini_set('track_errors', 1); if (!@ftp_put($my_ftp_conn_id, $tmpRemoteFileName, $localFileName, FTP_BINARY)) {    // error message is now in $php_errormsg    $msg = $php_errormsg;    ini_set('track_errors', $trackErrors);    throw new Exception($msg); } ini_set('track_errors', $trackErrors); 

EDIT:

Note that $php_errormsg is deprecated as of PHP 7.

Use error_get_last() instead.
