Betreff:  Variable Names


Hi,

I seem to be having a problem in assigning a value to an array where the
array is called dynamically.

e.g. the physical name for the array is "my_array", so:
my_array[1] = "test";
works fine.

$array_name = "my_array";
$array_name[1] = "test";
does not work.

I have tried $$array_name[1] = "test"; but to no avail.

Here is my code

/**
 * Adds any posted values from the application form to the session
 */
 function add_form_to_session() {
  foreach ($_POST AS $key => $value) {
   if (is_array($value)) {
    foreach ($value AS $subkey => $subvalue) {
     $_SESSION['ses-app-form']->$key[$subkey] = $subvalue;
     //echo "value: ".$key."<br>";
    }
   }

   else {
    $_SESSION['ses-app-form']->$key = $value;
    //echo "value: ".$key." = ".$value."<br>";
   }
  }
 }


Any Ideas?

Cheers,

Shaun
