What are common pitfalls when dealing with string processing in PHP, especially with special characters like "\"?
When dealing with special characters like "\", a common pitfall is that PHP interprets "\" as an escape character, which can lead to unexpected behavior when processing strings. To avoid this, you can use the double backslash "\\" to represent a single backslash in your string.
$string = "C:\\xampp\\htdocs\\";
echo $string; // Output: C:\xampp\htdocs\
