Question

I have a map from jquery:

82|81|83|84|85|86|87|88|89

I need to cycle through this map and use it in a mysql query, I want to do a while loop so that in the first iteration:

$ID = 82; $Position = 1;

second iteration:

$ID = 81; $Position = 2;

third iteration:

$ID = 83; $Position = 3;

… and so on. Thanks.

Answer 1

$arr = explode('|', $themap);
$length = count($arr);
for($i = 1; $i <= $length; $i++){
    // Here $i contains position
    // $arr[$i-1] contains the ID
}

PS. I highly recommend not putting your query inside the loop unless absolutely needed. It would be better to use a single query. You might be able to use MySQL’s CASE WHEN THEN END syntax to get what you want in a single query.
