Description: ------------ The parser doesn't recognized different parameter counts for function/method calls which had changed in different PHP versions. class_exists('whatever', false) should be PHP5 only, while it results in 4.0.0. In PHP 4 this call will create a warning. Test script: --------------- <?php require_once 'PHP/CompatInfo.php'; if (class_exists('whatever', false)) { // do something } $info = new PHP_CompatInfo('null'); $info->parseData(__FILE__); echo $info->getVersion(); Expected result: ---------------- 5.0.0 Actual result: -------------- 4.0.0

A solution exists with PHP_CompatInfo 2 See at https://github.com/llaville/php-compat-info Will be available with future stable release 2.2.0 when PHP 5.3.9 and PHP 5.4.0 will be released too
