What are the common issues when trying to display a database column as a link in PHP?

Common issues when trying to display a database column as a link in PHP include not properly formatting the HTML anchor tag, not concatenating the database column value with the link URL, and not escaping the database column value to prevent potential security vulnerabilities. To solve this, you should properly format the anchor tag, concatenate the database column value with the link URL, and escape the database column value using htmlspecialchars(). 

<?php
// Assume $row is an associative array containing data from the database
$linkUrl = 'https://example.com/';
$columnName = htmlspecialchars($row['column_name']);

echo '<a href="' . $linkUrl . $columnName . '">' . $columnName . '</a>';
?>
