I noticed on that tutorial that the column sid was the one used, not id, but never mind.
PHP Code:
<?php
$selected_id = 0;//The id to make bold
$query = "SELECT * FROM table";//Create the SQL query
$result = mysql_query($query);//Run the query
$while ($row = mysql_fetch_assoc($result)) {//Go through each row from the result, creating an array each time, with column names as the array keys
if ($row['id'] == $selected_id) {//If the id for that row is the same as the selected id
echo "<b>".$row['name']."</b>";//Output the name column for that row in bold
} else {
echo $row['name'];//Output the name column
}
echo "<br/>";//Put a line break, whatever happens
}//End of loop
?>
