来自根目录的PHP警告

我有一个php代码的问题

文件夹名称什么计数器此文件夹包含一个名为counter.php的php代码文件以及hitcount.txt文件

<?php

$filename = '../what-counter/hitcount.txt';
$handle = fopen($filename, 'r');
$hits = trim(fgets($handle)) + 1;
fclose($handle);

$handle = fopen($filename, 'w');
fwrite($handle, $hits);
fclose($handle);

// Uncomment the next line (remove //) to display the number of hits on your page.
echo $hits;

?>

下面的php代码在根目录文件中使用，也在回音的文件夹中使用

<?php include("../what-counter/counter.php"); ?>

问题 代码在文件夹中的文件中工作，但不在直接位于根目录中的文件中工作。 示例：index.php位于根目录中

使用此代码我收到此警告

<?php include("what-counter/counter.php"); ?>

要使$filename url和

在根目录和文件夹中的文件中工作，我可以对其执行什么操作？

或者：

• 包括文件的相对值：

  \uuuuu DIR\uuuuu./../somefile'/
  \uuuu DIR\uuuuu.'/somepath/somefile'

• 相对于已知目录包含：

  $\u服务器['DOCUMENT\u ROOT']

  经常使用，就像引导代码中的

  项目目录一样

• 将工作目录更改为已知的/static dir

  chdir（'/some/dir'）。不建议这样做，因为调用代码可能不希望这样

听起来像是绝对和相对文件问题

尝试替换：

$filename = '../what-counter/hitcount.txt';

使用，根据文件的确切位置，可以选择以下任一选项：

$filename = __DIR__ . '/what-counter/hitcount.txt';
$filename = dirname(__DIR__) . '/what-counter/hitcount.txt';

$filename = dirname(__FILE__) . '/what-counter/hitcount.txt';
$filename = dirname(dirname(__FILE__)) . '/what-counter/hitcount.txt';

或者（如果您使用的是旧的php安装），可以选择：

$filename = __DIR__ . '/what-counter/hitcount.txt';
$filename = dirname(__DIR__) . '/what-counter/hitcount.txt';

$filename = dirname(__FILE__) . '/what-counter/hitcount.txt';
$filename = dirname(dirname(__FILE__)) . '/what-counter/hitcount.txt';

如果我从文件中删除../并将其包含在index.php页面上，但不在文件夹文件中，则与..有关/
