Are there any best practices for handling file paths in PHP to ensure compatibility across different network setups?

When dealing with file paths in PHP, it's important to use the DIRECTORY_SEPARATOR constant to ensure compatibility across different operating systems. This constant will automatically insert the correct separator for the current environment (e.g., "/" for Unix-based systems and "\" for Windows). Additionally, using the realpath() function can help resolve any relative paths to their absolute counterparts, ensuring consistency in file path handling. 

// Example of handling file paths in PHP
$filePath = 'path/to/file.txt';
$absolutePath = realpath($filePath);
echo $absolutePath;
