if($type == 1) {
$data = array(
'phone' => $phone,
'pwd' => $pwd
);
$key = base64_encode(json_encode($data));
setcookie($name, $key, time() + 3600 * 24 * 7, '/', '', '', true);
}else{
setcookie($name,'' , time() - 3600 * 24 * 30, '/', '', '', true);
}
}

/**

*/
public function GetPassword($name){
$info = array();
if(!isset($_COOKIE[$name])){
$data['errorCode'] = 1;
}else{
if($_COOKIE[$name] == ''){
$data['errorCode'] = 1;
}else{
$key = json_decode(base64_decode($_COOKIE[$name], true),true);
if(!is_array($key)){
$data['errorCode'] = 1;
}else{
$data['errorCode'] = 0;
$info['phone'] = $key['phone'];
$info['pwd'] = $key['pwd'];
$info['type'] = 1;
}
}
}
if($data['errorCode'] == 1){
$info['phone'] = '';
$info['pwd'] = '';
$info['type'] = 0;
}
return $info;
}
