Question

having a file with the following for example:

DEFINE('INTERESTS_1','a');
DEFINE('INTERESTS_2','d');
DEFINE('INTERESTS_3','g');
DEFINE('INTERESTS_4','c');

Is it possible to open it, put it into an array and then ordering it ASC beforing echoing it all out using a loop?

Answer 1

// capture constant before loading the new ones
$before = get_defined_constants();

// require_file
// require_once 'somefile';

DEFINE('INTERESTS_1','a'); // this is for testing
DEFINE('INTERESTS_2','d'); // "
DEFINE('INTERESTS_3','g'); // "
DEFINE('INTERESTS_4','c'); // "

$new = array_diff(get_defined_constants(), $before);

// sort, or do whatever you want with those values
asort($new);

// debug output
foreach ($new as $constantName => $constantValue) {
  echo $constantName, ' ', $constantValue, "\n";
}
