Question

Lets say for example, I have a form, and i post the values to the next page via an array.
I would like to create a while loop that would print out the variables individually.
this is my problem.
I really have an XML document. This XML document I want it to change variables. So I am assuming that implementing the values i pass via an array from the form would need help from some sort of loop so im guessing the while loop will help because i need to stop the loop.

So I have a hotel form. if there are two rooms, I would like to make the while loop stop at two and insert the values from the array form post.
I know how to set up a while loop just need some kind guidance to insert the different values into the xml document.

Here is example:
* There are two rooms i want label 0 and label 1 to go into the child attribute tag, and child 2 and child 3 to go to the 2nd loop within the child attribute tag.

$label[0];
$label[1];
$label[2];
$label[3];
$NumberOfRooms = $_POST['NumbersOfRooms']; 
$count = '0';

while ($count > $NumberOfRooms){ //Assuming that there is two rooms 
$xml = '<checkIn>2012-10-15 </checkIn>
<checkOut>2012-10-18</checkOut>
<numberOfAdults>1</NumberOfAdults>
<numberOfChilderen>2</NumberOfChilderen>
  <ChildAges>
  <childAge age ='."3".' /> $label[0]; 
  <childAge age ='."3".' /> $label[1]
  </ChildAges>';
$count++;
}

I think this code should do the trick for you.

<?php
    $label[0];
    $label[1];
    $label[2];
    $label[3];
    $NumberOfRooms = $_POST['NumbersOfRooms']; 
    $xml="";

    for($count=0; $count<$NumberOfRooms; $count++)
    {
    $xml .= '<checkIn>2012-10-15 </checkIn>
    <checkOut>2012-10-18</checkOut>
    <numberOfAdults>1</NumberOfAdults>
    <numberOfChilderen>2</NumberOfChilderen>
      <ChildAges>
      <childAge age ='.$label[floor($count*2))].' />  
      <childAge age ='.$label[floor($count*2)+1].' />
      </ChildAges>';
    }
?>

The errors that I saw in your code were as follows:

• Your $count was defined as a string. You were comparing it to a number.
• Secondly, assuming $count started at zero, how was it ever going to be larger than the number of rooms? I think you got your < and > muddled up.
• You were overwriting the $xml variable each time you looped through your while statement.
• Lastly, it is just my opinion, but if you know you only want to loop through a certain number of times, use a for loop over a while – there is less chance of muddling up the logic/drop out conditions.
