[Resolved] foreach question

[eli03]

hello guys,

Is there a way i can come up w/ 2 variable using foreach? example:

foreach (($_POST['bd_size'][$i] as $var1) && ($_POST["bd_window_action"][$i] as $var2 ))
{
//condition here

}

obviously the script above don't work. 😃
Is there a way i can do this (getting 2 variable) in one foreach statement?

Are the keys for $POST['bd_size'][$i] and $POST["bd_window_action"][$i] the same? If so then you could do

foreach($_POST['bd_size'][$i] as $key => $value1) {
  $value2=$_POST['bd_window_action"][$i][$key];
}

what is $key? 😕

An array has keys and values, right? For example, the array$_GET might have a key 'action', which has a value 'queryDB'. So in a foreach loop, PHP will loop through each entry of the array. It will then assign each key and value, in turn, to some variables. In this case, it's $key=>$value, so the keys will be in $key, and the values will be in $value. There's nothing special about the names; they could be named anything, e.g.

$friends['john'] = 22;
$friends['jane'] = 21;

foreach ($friends as $name=>$age) {
   print $name . ' is ' . $age;
}

HTH,

Diego
