What are the potential consequences of not properly handling backslashes in PHP code?

Improperly handling backslashes in PHP code can lead to unexpected behavior or syntax errors, especially when dealing with strings or regular expressions. To solve this issue, you can use the PHP function addslashes() to properly escape backslashes in a string before using it in your code. 

// Properly handle backslashes in a string using addslashes()
$string = "This is a backslash: \\";
$escaped_string = addslashes($string);

echo $escaped_string;
