-

i want put time interval sftp connection in php. if time exceeds 60 seconds connect it, should disrupted , exception handled. don't know how it.

i tried do:

set_time_limit(60)

but, not work.

i want put time limit in function:

private function __connectsftp()     {         $this->sftp = new net_sftp($this->host, 22);           if (!$this->sftp->login($this->user, $this->password))         {             return $this->_requesterrormessage('could not connect server');          } else         {              return $this->__downloadfile();         }       }

i tried do:

$totime = time()+60;  while(time() != $totime){ //connection code }

but, sadly doesn't work @ all.
