PHP使用反射机制实现查找类和方法的所在位置,php所在位置
本文实例讲述了PHP使用反射机制实现查找类和方法的所在位置。分享给大家供大家参考,具体如下:
//参数1是类名,参数2是方法名 $func = new ReflectionMethod('UnifiedOrder_pub', 'getPrepayId'); //从第几行开始 $start = $func->getStartLine() - 1; //从第几行结束 $end = $func->getEndLine() - 1; //获取路径地址 $filename = $func->getFileName();
下面是摘抄的示例代码比较全面
<?php function a() { } class b { public function f() { } } function function_dump($funcname) { try { if(is_array($funcname)) { $func = new ReflectionMethod($funcname[0], $funcname[1]); $funcname = $funcname[1]; } else { //这个应该是当只有一个参数的时候就看做是本类的发放吧,大概,自行百度 $func = new ReflectionFunction($funcname); } } catch (ReflectionException $e) { echo $e->getMessage(); return; } $start = $func->getStartLine() - 1; $end = $func->getEndLine() - 1; $filename = $func->getFileName(); echo "function $funcname defined by $filename($start - $end)\n"; } function_dump('a'); function_dump(array('b', 'f')); $b = new b(); function_dump(array($b, 'f')); ?>

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,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP?
