If you want to "look-ahead" values in an associative or non-continuous array, this might
help:
<?php
$myArray =
{'one'=>1,'two'=>2,'five'=>5,'three'=>3}
$all_keys = array_keys($myArray);
foreach ( $all_keys as $key_index => $key ) {
$value =& $myArray[$key];
// $all_keys[$key_index+2] gives null if we go past the array boundary - be carefull there
$value2 =& $myArray[$all_keys[$key_index+2]] ;
...
}
?>
