Hi, Not sure where to report bugs, so sorry for writing here.
Using revision: At revision 5410 Runninig snippet: $include_path = get_include_path(); $include_path .= PATH_SEPARATOR . dirname(dirname(__FILE__)) . '/library/zf'; set_include_path($include_path); require_once("Zend/Loader.php"); Zend_Loader::loadClass('Zend_Validate_Alpha'); $f = new Zend_Validate_Alpha(); var_dump($f->isValid("test1234")); ##on localhost## Running: PHP 5.2.1 (cli) (built: Mar 24 2007 00:04:25) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies with Xdebug v2.0.0RC3, Copyright (c) 2002, 2003, 2004, 2005, 2006, 2007, by Derick Rethans Result from script: bool(false) ##on deployment## Running: PHP 5.1.6-0.dotdeb.2 (cli) (built: Aug 31 2006 16:25:11) Copyright (c) 1997-2006 The PHP Group Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies Result from script: bool(true) Expected result: bool(false) Is it possible to really be version problem?
