Betreff: [php] 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
