How can PHP be used to create a link list of tags from a database column and avoid duplicates?

To create a link list of tags from a database column and avoid duplicates, we can use PHP to query the database for distinct values in the column, then loop through the results to create a list of unique tags. We can then output these tags as links in HTML. 

<?php
// Assuming you have a database connection established

// Query to select distinct tags from the database column
$query = "SELECT DISTINCT tag_column FROM your_table";
$result = mysqli_query($connection, $query);

// Loop through the results to create a list of unique tags
$tags = array();
while($row = mysqli_fetch_assoc($result)) {
    $tags[] = $row['tag_column'];
}

// Output the tags as links
foreach($tags as $tag) {
    echo "<a href='#'>$tag</a>";
}
?>
