What are some best practices for handling image paths in PHP when dealing with multiple directories or subfolders?

When dealing with multiple directories or subfolders in PHP, it's important to handle image paths correctly to ensure that the images are properly displayed on the website. One best practice is to use the `__DIR__` magic constant to get the current directory path and then concatenate it with the relative path to the image file. This ensures that the image path is always relative to the current directory, regardless of the directory structure. 

<?php
// Get the current directory path
$currentDir = __DIR__;

// Relative path to the image file
$imagePath = '/images/image.jpg';

// Concatenate the current directory path with the image path
$fullImagePath = $currentDir . $imagePath;

// Output the full image path
echo $fullImagePath;
?>
