What are the best practices for handling dynamically changing links in PHP scripts?

When handling dynamically changing links in PHP scripts, it is best practice to use variables or configuration files to store the links. This allows for easy updating of the links without having to modify the code. By separating the links from the code, it also improves maintainability and makes it easier to manage changes in the future.

// Define a variable to store the dynamic link
$link = "https://example.com";

// Use the variable in your code wherever the link is needed
echo "<a href='$link'>Click here</a>";
