Question

I have an array which contains numbers like “331,554,22” or it could be “45”, lets say the array is called $numbers.

I want to loop through the array and for each number or entry in it, do a SQL query like

UPDATE members SET x=1 where id=$numbers[x]

Could someone help me along?

UPDATE: Also, say I store the query values in a text field in my database called nums and it looks like eg. “45,656,23”, how would I convert that to an array format?

Answer 1

if the veriable "331,554,22" is not an array (string),
explode it first

$numbers = explode(',',$numbers);

and then.

Foreach :

 foreach ($numbers as $number)
        {
          //query like  SET x=1 where id=$number
        }

For :

    for($i = 0; $i < count($numbers); $i++)
    {
       //query like  SET x=1 where id=$numbers[$i]
    }

if x is always 1 you can use in,

$query = "UPDATE table SET x = 1 WHERE id  IN(" . implode(',',$numbers)  . ")"

and if the $numbers variable is string, and x will be 1 for each ID, forget all of I wrote and try this only 🙂

$query = "UPDATE table SET x = 1 WHERE id  IN({$numbers})"
