How to do

I have a compatible PHP4/5 application with optional PHP5 code. How to ignore only PHP 5 code ?

If you want to ignore all PHP5 code (functions, constants, extensions), you only need to add a line on your parsing (file, directory, string) options: "ignore_versions". In this example all PHP 5.0.0 to 5.2.0 code will be ignored when parsing current directory.

      
<?php
require_once 'PHP/CompatInfo.php';

$dir = dirname(__FILE__);
$options = array('ignore_versions' => array('5.0.0', '5.2.0'));

$pci = new PHP_CompatInfo();
$res = $pci->parseDir($dir, $options);
var_dump($res);
?>
