Return value

array - a hash which contains information keys: ignored_functions, ignored_extensions, ignored_constants, max_version, version, extensions, constants, tokens, cond_code

Example

<?php
require_once 'PHP/CompatInfo.php';
$pci = new PHP_CompatInfo();
$input = '<?php
$nl = "\n";
echo "$nl Rfc3339 = " . DATE_RFC3339;
echo "$nl RSS = " . DATE_RSS;
?>';
$res = $pci->parseString($input);
var_export($res);
?>

We get such result.

array (
  'ignored_functions' =>
  array (
  ),
  'ignored_extensions' =>
  array (
  ),
  'ignored_constants' =>
  array (
  ),
  'max_version' => '',
  'version' => '5.1.3',
  'extensions' =>
  array (
  ),
  'constants' =>
  array (
    0 => 'DATE_RFC3339',
    1 => 'DATE_RSS',
  ),
  'tokens' =>
  array (
  ),
  'cond_code' =>
  array (
    0 => 0,
    1 =>
    array (
      0 =>
      array (
      ),
      1 =>
      array (
      ),
      2 =>
      array (
      ),
    ),
  ),
)

That means we need PHP 5.1.3 minimum to run this chunk of code, due to usage of DATE_RFC3339 constant.
