Paths in PHP not work.

[pinkod02]

How to figure out the paths, why the styles are not applied, the file is not found, I tried many methods, but as a rule nothing works, it happens that the main page applies styles, in other files there is none or there is no file at all, it is clear that you need to register the paths, but how? I tried $path = $_SERVER['DOCUMENT_ROOT']; this does not work

Let's see a little more code. Also, read https://www.php.net/manual/en/function.error-log.php to see how to log what your current directory is and more.

Can you please show us your code and explain what the expected behavior is and what is not working?

$_SERVER['DOCUMENT_ROOT']; reflects the path on the server that serves as the root path / for the website. When you set $path = $_SERVER['DOCUMENT_ROOT']; you are setting a PHP variable named $path to whatever the value of the document root is, but it doesn't actually do anything with that beyond set the variable.

It's possible you're using a CMS or framework of some kind that does something with a $path variable, but without seeing any code, it wouldn't do anything.

Also, when you say styles, are you referring to the theme files for a CMS? Or CSS stylesheets? I'm not sure what you're referring to here.

To resolve path issues in PHP, ensure your CSS files are correctly linked using absolute paths like base_url/style.css or relative paths based on your folder structure. Use echo $_SERVER['DOCUMENT_ROOT'] to debug and confirm the correct path to your files.

If your PHP paths aren't working and styles aren’t applying, it's likely due to incorrect file or directory paths.

Use Absolute Paths: Use $_SERVER['DOCUMENT_ROOT'] for full paths, like this:

$basePath = $_SERVER['DOCUMENT_ROOT'];
include $basePath . '/your-folder/file.php';

Check File Existence: Verify if the file exists using:

if (file_exists($basePath . '/your-folder/file.php')) {
    echo "File found!";
} else {
    echo "File not found!";
}

Fix Styles for Subdirectories: Ensure correct paths for styles by using relative paths (../) or absolute paths (/).

I'm not sure if you're still following this thread, but I think you're confounding paths in the HTML code relative to the domain root, and paths in the PHP code relative to the server's file system root.

It sounds like a path issue. Ensure you're using relative paths consistently or switch to absolute paths starting from the root (/css/style.css). For PHP, $_SERVER['DOCUMENT_ROOT'] works if you're correctly appending the file's relative path. Also, check if your server or framework alters paths dynamically. Debug using browser dev tools (F12) to confirm the correct file paths and check for 404 errors.
