PHP:回声结果编号

I am fetching a number of results from my database using a mysql_query. What I need to do is echo the result number, along with the result itself.

In other words, if my query fetches 3 results, I would like the first result to have a 1 beside it, and the second result a 2 and so on. I need the numbers to start at 1, not 0.

note: I do not mean mysql_num_rows as that only tells me how many results, not the result number itself.

Here is my query information:

$primary_img_query = "SELECT imgURL, imgTitle FROM primary_images WHERE primaryId=16";
$primary_img_data = mysql_query($primary_img_query) or die('MySql Error' . mysql_error());

while($row = mysql_fetch_assoc($primary_img_data)) { 
    echo "<img src='new_arrivals_img/thumbnails/".$row['imgURL']."'>";//this is where I want the result number echoed
  }

    Make a counter:

    $count = 1;
    
    while(...){
       echo $count++;
    }
    

    In your case:

    $count = 1;
    
    while($row = mysql_fetch_assoc($primary_img_data)) { 
       echo $count++;
       echo "<img src='new_arrivals_img/thumbnails/".$row['imgURL']."'>";
    }
