How can special characters be handled in file paths in PHP?

Special characters in file paths can be handled by using the `urlencode()` function to encode the special characters before using the path in PHP functions. This ensures that the special characters are properly interpreted by the file system without causing any issues.

// Example of handling special characters in file paths
$filePath = '/path/to/file with special characters.txt';
$encodedPath = urlencode($filePath);

// Now you can use $encodedPath in PHP functions without issues
echo file_get_contents($encodedPath);
