Will Fitch, sorry i didn't know that i contacted one of the dev to post it
on behalf of me and he said its ok to post here, i'll post it there right
away
Paul Dragoonis, there is 3 ways to do it in userland codes.
Public function dir_exists($dir)
{
if (!$this->conn_id)
return false;
$currentDir = ftp_pwd($this->conn_id);
if ( ftp_chdir($this->conn_id, $dir) )
{
ftp_chdir($this->conn_id, $currentDir);
return true;
}
return false;
}
this function above attempts to change directory it see if its exists or
not. and produce E_WARNING if the dir doesn't exists
and there is
echo ( is_dir("ftp://{$username}:{$password}@{$server}{$dir}";) ) ? true :
false;
which require that you re-authenticate
Public function dir_exists2($dir)
{
if ( !$this->conn_id )
return false;
$orginal = $dir;
if ( substr($dir, -1) === '/' )
$dir = substr($dir, 0, strlen($dir)-1);
$dir = substr($dir, 0, strlen($dir)-strlen(strrchr($dir,'/')));
$res = ftp_nlist($this->conn_id, '-dF '. $dir);
if ( isset($res) AND is_array($res) )
{
foreach ($res as $key => $value)
{
if ($value === $orginal)
return true;
}
}
return false;
}
this function i hacked my self to stop the E_WARNING from flooding my error
log files. it works but kinda ugly and so hackish, and i dont think it will
work nicely if there is too many directories.
