What potential pitfalls should be considered when using explode to manipulate file paths in PHP?

One potential pitfall when using explode to manipulate file paths in PHP is that it may not handle all possible file path variations correctly, especially if the paths contain special characters or different directory separators. To avoid this issue, it is recommended to use the PHP built-in function `realpath()` to normalize the file path before using explode. 

// Example of using realpath() before exploding file paths
$file_path = '/path/to/file.txt';
$normalized_path = realpath($file_path);
if($normalized_path){
    $path_parts = explode('/', $normalized_path);
    // Continue with path manipulation using $path_parts
} else {
    echo "Invalid file path";
}
