Question

I have some data in a database and its getting outputted with an ORDER BY category and I was wondering how do I only display the category once?

  $SQL = mysql_query("SELECT id,name,category FROM table ORDER BY category,id");

So my script iterates through the table and sorts all the items by the category name.

I want to be able to display the category name once so then the rest of the values can fall within that category

I currently have something like this

while($r = mysql_fetch_array($SQL){
  $name = $r['name'];
  $category = $r['category'];

  echo $category; //I want to be able to echo this once
  echo $name; // this will be echoed many times depending on the category this falls into
}

Answer 1

$category = null;
while($r = mysql_fetch_array($SQL){
  $name = $r['name'];

  if ($category != $r['category']) {
      $category = $r['category'];

      echo $category; //I want to be able to echo this once
  }
  echo $name; // this will be echoed many times depending on the category this falls into
}
