What are the best practices for passing dynamic variables in a URL using a button in PHP?

When passing dynamic variables in a URL using a button in PHP, it is important to properly sanitize and validate the input to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. One common practice is to use the GET method to pass variables through the URL. You can achieve this by setting the button's form action to the current page and appending the dynamic variables as query parameters in the URL. 

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="get">
    <input type="hidden" name="dynamic_variable" value="value_here">
    <button type="submit">Submit</button>
</form>
