[Resolved] array

[bampot]

i have an array which contains info such as
('555'=> 1, '666' => 1) etc

however i need to pass this to a function which requires
('555', '666')

how can i strip the array of the values?

thanks in advance

ahaa array_keys turned
Array ( [555] => 1 [666] => 1 )

to this

Array ( [0] => 555 [1] => 666 )

Why you would want this I'm not sure 🙂

$array = array( 555 => 1, 666 => 2 );
foreach( array_keys($array) as $value){
  $keys[] = $value;
}
myFunction($keys[0], $keys[1]);

This is going to break as soon as you add more elements to the first array. Perhaps it can be made modular if you explain what you are doing 🙂

i'm using an array from a session set shopping cart to create a 'customers who bought this also bought' script. so the array $items is sent to this function to store when two or more items are purchased at the same time.

however the original array would not store, this seems to be working for the moment with array_keys, can you forsee any probs with it?

function setRel($items)
{ 

  while($item=array_pop($items))
  {

foreach ($items as $each)
{

  if ($item == $each){continue;}

	$pair=array($item,$each);

	sort($pair);

	list($i1,$i2)=$pair;

	$conn = db_connect();

	list($times)=@mysql_fetch_row(@mysql_query("select times from relsel where id1='$i1' and id2='$i2'"));

	$times++;

	@mysql_query("replace relsel set id1='$i1',id2='$i2',times='$times'");

}

  }

}

The above code snippet doesn't use array_keys() ?

oops

call function after array_keys

$items = $_SESSION['cart'];
	  $count = (count($items));
      if($count > 1)
      {
        $items =(array_keys($items));
		setRel($items);
      }

Ah didn't realise that you were passing the entire key list rather than specific keys. Shouldn't be a problem there.
