I have this code that prints out columns in my DB and adds a column "Profit" for me. Distance is calculated in a complex way and so is done in a loop, while the transformation of distance to "profit" is done as it is printed out.
Ne yapmak istiyorum "dönem karı" nın azalan sırayla onları baskı olduğunu. Ben en iyi yolu oradan onları baskı bir dizi saklayın ve "orada bunları sıralamak" olacağını inanıyorum (ama bilmiyorum).
How do I determine what row of the array to stick them in?
How do I sort in an array?
How do I loop through the array so I can't print them back out?
//display results
// now we retrieve the routes from the db
$query = "SELECT * FROM routes ORDER BY `id`;";
// run the query. if it fails, display error
$result = @mysql_query("$query") or die('<p class="error">There was an unexpected error grabbing routes from the database.</p>');
