What potential issues can arise when trying to save file paths to a text file in PHP, and how can these be resolved?

One potential issue when saving file paths to a text file in PHP is that the paths may contain special characters or spaces that can cause errors when reading the file later. To resolve this, you can use the PHP function `urlencode()` to encode the file paths before saving them to the text file. 

// Encode file path before saving to text file
$filePath = '/path/to/file with spaces.txt';
$encodedPath = urlencode($filePath);

// Save encoded file path to text file
$file = fopen('file_paths.txt', 'a');
fwrite($file, $encodedPath . "\n");
fclose($file);
