What are some best practices for preserving special characters like \n and \t in PHP when writing to a file?

Special characters like \n and \t can be preserved in PHP when writing to a file by using double quotes around the string that contains these characters. This allows PHP to interpret the escape sequences correctly. Alternatively, you can use the PHP function addslashes() to escape special characters before writing to the file. 

// Using double quotes to preserve special characters
$file = fopen("output.txt", "w");
fwrite($file, "This is a line with a newline character \n and a tab character \t");
fclose($file);
```

```php
// Using addslashes() to escape special characters
$file = fopen("output.txt", "w");
$text = "This is a line with a newline character \n and a tab character \t";
$text = addslashes($text);
fwrite($file, $text);
fclose($file);
