Question

If I have a table in a MySQL DB, with fields id and position amung others.

Then in PHP I have an array like this:

Array
(
    [0] => 1
    [1] => 3
    [2] => 8
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
)

Where the array key should map to the position and the array value should map to the id.

For example, If I made a call for every array value the first would be

UPDATE table SET position = 0 WHERE id = 1

Is there a way I could do all this in 1 call?

Answer 1

$string = "";
foreach($array as $k => $v)
 $string .= "UPDATE table SET position = ".$v." WHERE id = ".$k.";";
mysql_query($string);
