What are the best practices for passing parameters in PHP to display content in a specific column when clicking on a link?

When passing parameters in PHP to display content in a specific column when clicking on a link, it's best to use GET parameters in the URL. This way, you can retrieve the parameter value using the $_GET superglobal in PHP and use it to determine which content to display in the specific column.

<?php
// Check if a parameter is passed in the URL
if(isset($_GET['column'])) {
    $column = $_GET['column'];
    
    // Display content based on the column parameter
    if($column == 'column1') {
        echo "Content for column 1";
    } elseif($column == 'column2') {
        echo "Content for column 2";
    } else {
        echo "Invalid column parameter";
    }
}
?>

<a href="?column=column1">Display Column 1</a>
<a href="?column=column2">Display Column 2</a>
