How can developers avoid errors when dealing with spaces in file paths in PHP?

When dealing with spaces in file paths in PHP, developers can avoid errors by using the `urlencode()` function to properly encode the file path before using it in functions like `file_get_contents()` or `include()`. This ensures that spaces are converted to `%20` and do not cause issues with file operations.

$file_path = '/path/to/file with spaces.txt';
$encoded_file_path = urlencode($file_path);
$file_contents = file_get_contents($encoded_file_path);
echo $file_contents;
