PHP uses the reflection mechanism to find the location of classes and methods. The location of php

The example in this article describes the use of reflection mechanism by PHP to find the location of classes and methods. Share it with everyone for your reference, the details are as follows:

//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();

The following is a more comprehensive excerpt of the sample code

<&#63;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'));
