PHP implements Token instance method

This article mainly shares with you the example methods of implementing Token in PHP, hoping to help everyone.

public function set_token($user_name){
    $information ['state'] = false;    $time = time();    $header = array(        'typ' => 'JWT'
    );    $array = array(        'iss' => 'auth', // 权限验证作者
        'iat' => $time, // 时间戳
        'exp' => 3600, // token有效期，1小时
        'sub' => 'demo', // 案例
        'user_name' => $user_name
    ) // 用户名
    ;    $str = base64_encode(json_encode($header)) . '.' . base64_encode(json_encode($array)); // 数组转成字符
    $str = urlencode($str); // 通过url转码
    $information ['token'] = $str;    $this->save_token($user_name, $information ['token']); // 将用户token存放进用户数据库
    $information ['username'] = $user_name; // 返回用户名
    $information ['state'] = true;    return $information;
}

Notes:
1. Function save_token(), saves the user's current token in the user table for verification
2. Base64_encode and base64_decode encryption and decryption functions
(1 ) Encryption:

$str='www.php.cn'; //定义字符串 
echo base64_encode($str);  // 输出编码后的内容为： d3d3LmpiNTEubmV0IOiEmuacrOS5i+Wutg==

(2) Decryption:

$str='d3d3LmpiNTEubmV0IOiEmuacrOS5i+Wutg==';     //定义字符串 
echo base64_decode($str); //输出解码后的内容

3. Arrays and objects, convert json format, and reverse
(1) json_encode() is used to convert arrays and objects , converted to json format:

$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);　　
echo json_encode($arr);　
结果为：
{"a":1,"b":2,"c":3,"d":4,"e":5}

(2)json_decode() is used to convert json text into the corresponding PHP data structure:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
结果就是生成一个PHP对象：
object(stdClass)#1 (5) {　　　　
["a"] => int(1)　　　　
["b"] => int(2)　　　　
["c"] => int(3)　　　　
["d"] => int(4)　　　　
["e"] => int(5)　　
}　

4. Chinese processing

echo urlencode("中文-_. ")."\n"; //%D6%D0%CE%C4-_.+      //将中文文字转换成urlencode文字编码
echo urldecode("%D6%D0%CE%C4-_. ")."\n"; //中文-_.       //将urlencode文字编码转换成中文文字

public function set_token($user_name){
    $information ['state'] = false;    
    $time = time();    
    $header = array(        'typ' => 'JWT'
    );    $array = array(        'iss' => 'auth', // 权限验证作者
        'iat' => $time, // 时间戳
        'exp' => 3600, // token有效期，1小时
        'sub' => 'demo', // 案例
        'user_name' => $user_name
    ) // 用户名
    ;    
    $str = base64_encode(json_encode($header)) . '.' . base64_encode(json_encode($array)); // 数组转成字符
    $str = urlencode($str); // 通过url转码
    $information ['token'] = $str;    
    $this->save_token($user_name, $information ['token']); // 将用户token存放进用户数据库
    $information ['username'] = $user_name; // 返回用户名
    $information ['state'] = true;    return $information;
}
