Question

我的php代码有问题。

文件夹名称 what-counter此文件夹包含一个文件，其中包含以下名为counter.php的php代码，也包含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;

?>

以下php代码在根目录文件中也用于文件夹中的文件中，这些文件回显了命中。

<?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。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"); ?>

使用此代码我收到此警告

我可以对$ filename url和<?php include("../what-counter/counter.php"); ?>做什么让它在根目录和文件夹中的文件中工作？

Answer 1

或者：

包含相对文件：__DIR__.'/../somefile'; / __DIR__.'/somepath/somefile';
包含相对于已知目录的内容：$_SERVER['DOCUMENT_ROOT']经常被用作PROJECT_DIR - 就像您的引导代码中的define()一样。
将工作目录更改为已知/静态目录chdir('/some/dir');。不推荐使用，因为调用代码可能不会这样。

Answer 2

听起来像绝对vs相对文件问题......

尝试更换：

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

根据文件的确切位置，使用以下任一项：

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

或者（如果您使用旧的PHP安装）：

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