PHP SQL Update array

Question

I originally was satisfied with the following in order to update row 1 and row 2 to the same value (status=1)

if ($_POST){
    $sql =\"UPDATE table SET  status =

You can loop through the arrays using a for loop and exec a query for each one (Radu Vlad answer), or you can build a long query and execute it once, something like this:

if ($_POST){
    $sql = ""; // Blank string
    $len = count($array_id); // Number of iterations
    for ($i = 0; $i < $l; $i++) { // Enter the loop
        $sql .= "UPDATE 
                  table
                SET
                  status = {$array_status[$i]}
                WHERE id = {$array_id[$i]};"; // Append the query
    }
    db()->query($sql);

    if(db()->query($sql)){
        echo "Update Successful";
    } 
    else{
        echo "Update Unsuccessful";
    }
}

When the val of $i is 0, then $array_id[$i] will print the first element, when $i is 1, $array_id[$i] will print the second element, and so on.

Using .= you append text to a string. By the end of the loop, $sql will be a string with 3 queries ('UPDATE ... SET ...; UPDATE ... SET ...; UPDATE ... SET ...;').

Not sure if it's the best way, though. But you get the idea.
