What is the issue with using hashtags in variables in PHP?

Using hashtags in variables in PHP can cause conflicts because hashtags are used to denote comments in PHP code. This can lead to syntax errors and unexpected behavior in your code. To solve this issue, it is recommended to avoid using hashtags in variable names and choose a different naming convention that does not include special characters like hashtags.

// Incorrect variable name with hashtag
$variable#name = "Hello World";

// Correct variable name without hashtag
$variable_name = "Hello World";
