How can PHP paths be properly defined to avoid errors when accessing files?

When defining paths in PHP, it is important to use the correct directory separator for the operating system being used. To avoid errors when accessing files, it is recommended to use the `DIRECTORY_SEPARATOR` constant in PHP, which automatically selects the correct separator based on the operating system. This ensures that paths are properly formatted and compatible across different environments. 

// Define a file path using DIRECTORY_SEPARATOR
$filePath = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.txt';

// Access the file using the defined path
$fileContents = file_get_contents($filePath);
echo $fileContents;
