Provides two built-in methods that can be used directly in the project, which is very convenient

/**
* 记住密码/清空密码
*
* @param $phone
* @param $pwd
* @param $name
*/
public function SeTpassword($phone, $pwd , $name, $type){
if($type == 1) {
$data = array(
&#39;phone&#39; => $phone,
&#39;pwd&#39; => $pwd
);
$key = base64_encode(json_encode($data));
setcookie($name, $key, time() + 3600 * 24 * 7, &#39;/&#39;, &#39;&#39;, &#39;&#39;, true);
}else{
setcookie($name,&#39;&#39; , time() - 3600 * 24 * 30, &#39;/&#39;, &#39;&#39;, &#39;&#39;, true);
}
}

/**
* 得到保存的密码
* @param $name
* @return mixed
*/
public function GetPassword($name){
$info = array();
if(!isset($_COOKIE[$name])){
$data[&#39;errorCode&#39;] = 1;
}else{
if($_COOKIE[$name] == &#39;&#39;){
$data[&#39;errorCode&#39;] = 1;
}else{
$key = json_decode(base64_decode($_COOKIE[$name], true),true);
if(!is_array($key)){
$data[&#39;errorCode&#39;] = 1;
}else{
$data[&#39;errorCode&#39;] = 0;
$info[&#39;phone&#39;] = $key[&#39;phone&#39;];
$info[&#39;pwd&#39;] = $key[&#39;pwd&#39;];
$info[&#39;type&#39;] = 1;
}
}
}
if($data[&#39;errorCode&#39;] == 1){
$info[&#39;phone&#39;] = &#39;&#39;;
$info[&#39;pwd&#39;] = &#39;&#39;;
$info[&#39;type&#39;] = 0;
}
return $info;
}
