Question

I am using PHP 5.3.6

I have the following code below. Everything works fine except for the last line which attempts to to return a value based on the position in the array as opposed to the associative name. Can anyone explain why this takes place and how I can build the array so that I can reference an item either by the associative name or position number?

Thanks.

<?php
class myObject {
  var $Property;
  function myObject($property) {
    $this->Property = $property;
  }
}
$ListOfObjects['form_a'] = new myObject(1); 
$ListOfObjects['form_b'] = new myObject(2); 
$ListOfObjects['form_c'] = new myObject(3); 
$ListOfObjects['form_d'] = new myObject(4); 

echo "<pre>";
print_r($ListOfObjects);
echo "</pre>";

echo "<hr />";
foreach ($ListOfObjects as $key => $val) {
    echo "<li>" . $ListOfObjects[$key]->Property . "</li>";
}

echo "<hr />";
echo "<li>" . $ListOfObjects['form_a']->Property . "</li>"; // Works ok.

//Edit: ------------------------------------------------------------
//Edit: Everything above is for context only
//Edit: I'm only interested in the line below and why it does not work
//Edit: ------------------------------------------------------------

echo "<li>" . $ListOfObjects[0]->Property . "</li>"; //Does not work.
?>

function value_from_index($a,$k){
    return array_slice($a,$k,1);
}
