What are some common pitfalls when trying to include special characters like hashtags in PHP variables?

When including special characters like hashtags in PHP variables, one common pitfall is forgetting to properly escape the characters to ensure they are treated as literal characters and not interpreted as part of the code. To solve this issue, you can use the addslashes() function to escape the special characters before assigning the value to the variable. 

$hashtag = "#php";
$escaped_hashtag = addslashes($hashtag);

echo $escaped_hashtag; // Output: \#php
