How do I define an array value from a integer?

Okay below I have attached my code, I'm trying to use the $current_statement and $next_statement to define the values in the array. the $current_statement is = to 7 and the $next_statement is = to 8. What I'm trying to do is define the 7th and 8th value in the array from the using the two values from $current_statement and $next_statement. 

   <?
       $date = array('16-01-14','16-01-28','16-02-14','16-02-28','16-03-14','16-03-28',
       '16-04-14','16-04-28','16-05-14','16-05-28','16-06-14','16-06-28','16-07-14',
       '16-07-28','16-08-14','16-08-28','16-09-14','16-09-28','16-10-14','16-10-28',
       '16-11-14','16-11-28','16-12-14','16-12-28');    


        $currentdate = date('y-m-d');


        foreach ($date as $i => $d) {
        if ($currentdate >= $d && ($i == count($date)-1 || $currentdate < $date[$i+1])) {
            $current_statement = $i;
            $next_statement = $i+1;
        } 

        }

    ?>

Example

I'm trying to use the two numeric values from the $current_statement and the $next_statement to select the value from the array. So for example if the $current_statement was = to 7 it would select the 7th value from the array and define it as a separate variable. And if the $next_statement was = to 8 it would select the 8th value from the array and define it as a separate variable. So I could easily echo out both variables.

I think you need to prevent the index out of bound exception:

$current_statement  = false;
$next_statement     = false;
foreach ($date as $i => $d) 
{
    if ($id<count($date)-1 && ($currentdate >= $d && ($i == count($date)-1 || $currentdate < $date[$i+1]))) 
    {
        $current_statement  = $i;
        $next_statement     = $i+1;
    } 
}
if($current_statement)
{
    $current_date   = $date[$current_statement];
    $next_date      = $date[$next_statement];
}

And shortly, if you don´t need the $current_statement and $next_statement variables more:

foreach ($date as $i => $d) 
{
    if ($id<count($date)-1 && ($currentdate >= $d && ($i == count($date)-1 || $currentdate < $date[$i+1]))) 
    {
        $current_date   = $date[$i];
        $next_date      = $date[$i + 1];
    } 
}

Forget this answer
You are preventing with this clausure: $i == count($date)-1

I am not totally clear on your requirement, so this answer is a bit of a guess, which of course I should not really do. But do you mean something like this

<?php
    $date = array('16-01-14','16-01-28','16-02-14','16-02-28','16-03-14',
                  '16-03-28','16-04-14','16-04-28','16-05-14','16-05-28',
                  '16-06-14','16-06-28','16-07-14', '16-07-28','16-08-14',
                  '16-08-28','16-09-14','16-09-28','16-10-14','16-10-28',
                  '16-11-14','16-11-28','16-12-14','16-12-28');    

    $currentdate = date('y-m-d');

    foreach ($date as $i => $d) {
        if ($currentdate >= $d && ($i == count($date)-1 || $currentdate < $date[$i+1])) {
            echo 'Current statement date = ' . $date[$i];
            echo 'Next statement date = ' . $date[$i+1];
        } 
    }
?>

In which case you do not need the 2 variables you created, you can just use $i and $i+1
