php—Serializable interface
Customized serialization interface.
Classes implementing this interface will no longer support __sleep() and __wakeup(). Whenever an instance needs to be serialized, the serialize method will be called. It will not call __destruct() or have other effects unless this method is called programmatically. When data is deserialized, the class will be aware and call the appropriate unserialize() method instead of calling __construct(). If you need to execute the standard constructor, you should handle it in this method.
Interface Summary
Serializable {
/* 方法 */
abstract public string serialize ( void )
abstract public mixed unserialize ( string $serialized )
}Example #1 Usage Example
<?php
class obj implements Serializable {
private $data;
public function __construct() {
$this->data = "My private data";
}
public function serialize() {
return serialize($this->data);
}
public function unserialize($data) {
$this->data = unserialize($data);
}
public function getData() {
return $this->data;
}
}
$obj = new obj;
$ser = serialize($obj);
$newobj = unserialize($ser);
var_dump($newobj->getData());
?>The output of the above routine is similar to:
string(15) "My private data"
Method List
Serializable::serialize — String representation of the object
Serializable::unserialize — Construct Object

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
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,
