Are there any specific PHP functions or methods that can help resolve file path issues in scripts?

When working with file paths in PHP scripts, it's common to encounter issues related to the correct formatting of paths, especially when dealing with different operating systems. One way to resolve these issues is by using the `realpath()` function, which returns the canonicalized absolute pathname of a given path. This function helps to resolve any symbolic links or relative path elements in the specified path. 

// Example of using realpath() to resolve file path issues
$path = '/var/www/html/../public_html/index.php';
$canonical_path = realpath($path);

echo $canonical_path;
