How can the unset() function be utilized to address the issue in the PHP code?

The issue in the PHP code is that the variable $name is not being unset after its use, which can lead to potential bugs or memory leaks in the program. To solve this issue, we can utilize the unset() function to remove the variable from memory once it is no longer needed.

$name = "John Doe";

// Code that uses the $name variable

unset($name); // Unset the $name variable to free up memory
