How can the backslash be represented as a string in PHP?

To represent a backslash as a string in PHP, you need to escape the backslash itself by using another backslash before it. This is because the backslash is a special character in PHP and is used for escaping characters. By adding an extra backslash before the backslash, you are telling PHP to treat it as a literal character rather than an escape character.

// Representing a backslash as a string in PHP
$backslash = "\\";

echo $backslash; // Output will be a single backslash
