php - 我如何在函数中使用 log4php

Question

在具有函数的类中使用 log4php 的正确形式是什么？

<?php
include_once 'log4php-2.3.0/src/main/php/Logger.php';

class template
{
  public static temp1;
  public static temp2;
  Logger::configure($path . '\commons\log4php-2.3.0\config.xml');
  $log = Logger::getLogger('myLogger');

  public static function example1()
  {

  }

  public static function example2()
  {

  }

}

例如，我如何 $log->fatal($error);在两个函数中调用该行？我应该重新声明每个 $log 还是如何？

A simple example from Reference

// Include and configure log4php
include('log4php/Logger.php');
Logger::configure('config.xml');

/**
 * This is a classic usage pattern: one logger object per class.
 */
class Foo
{
    /** Holds the Logger. */
    private $log;

    /** Logger is instantiated in the constructor. */
    public function __construct()
    {
        // The __CLASS__ constant holds the class name, in our case "Foo".
        // Therefore this creates a logger named "Foo" (which we configured in the config file)
        $this->log = Logger::getLogger(__CLASS__);
    }

    /** Logger can be used from any member method. */
    public function go()
    {
        $this->log->info("We have liftoff.");
    }
}

$foo = new Foo();
$foo->go();
