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); // no need since PCI 1.8.0
?>
We get such result.
array ( 'ignored_functions' => array ( ), 'ignored_extensions' => array ( ), 'ignored_constants' => array ( ), 'max_version' => '', 'version' => '5.1.3', 'classes' => array ( ), 'extensions' => array ( ), 'constants' => array ( 0 => 'DATE_RFC3339', 1 => 'DATE_RSS', ), 'tokens' => array ( ), 'cond_code' => array ( 0 => 0, ), )
That means we need PHP 5.1.3 minimum to run this chunk of code, due to usage of DATE_RFC3339 constant.
