PHP数组和Json之间的转换详解
在php中数组与json转换很简单,我们只要使用json_encode() 和 json_decode()。很容易理解,json_encode()就是将PHP数组转换成Json。相反,json_decode()就是将Json转换成PHP数组。
例如:
代码如下 | 复制代码 |
$array = array("name" => "Eric","age" => 23); |
程序将打印出 :
{“name”:”Eric”,”age”:23}
再看下面的例子:
代码如下 | 复制代码 |
$array = array(0 => "Eric", 1 => 23); |
程序将打印出 :
["Eric",23]
这样就可以将 json 转换成数组形式了,key 保持原来格式
代码如下 | 复制代码 |
$json = ’{"name":"zhangsan","age":20,"sex":"nan"}’; print_r(json_decode($json,true)); |
这样的json数据解析后 就会成为下面这样的数组
Array
(
[name] => zhangsan
[age] => 20
[sex] => nan
)

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
