Hello,
the problem is in this part of code $key -> $value
This notation means that you are trying to access property $value on the object $key.
Just replace it with $key => $value and you will get the result as expected.

Hello;
I have this section of code:
@include('tmp_index.php');
foreach($index as $key -> $value)
{
if($input == $key)
{
$target_file = $value;
}
}
And I am getting this error:
Fatal error: Cannot access empty property in <path>/confirmation.php on line 131
Several questions:
How long can an index be in an associative array? (the indexes I use in this array are 32 character hashes)
Can it start with a number (since a hash can start with a number)
Can I use $index as an array name? (I do not remember off hand what the reserved key words are)
I am not sure what the "empty property" is that it is referring to.
Thank you in advance for info;
