Description: ------------ ## from the PEAR QA team ## ## quality-assurance related ## ## PHP 5 compatibility issue ## Dear package maintainer, your package makes use of the assignement of new values to $this. This methodis possible in PHP 4 but will throw an error with PHP 5 [1]. Please take care of this issue forPHP5 compatibility reasons. Please answer to this bugreport directly through the PEAR bug tracker or the mailinglist pear-qa@lists.php.net . With kind regards, PEAR QA Team [1] http://www.php.net/ChangeLog-5.php#5.0.0b4 Reproduce code: --------------- FILE: '/php/pear/XML_XPath/XPath.php' : /php/pear/XML_XPath/XPath.php(101): $this = $result; /php/pear/XML_XPath/XPath.php(276): $this = null; FILE: '/php/pear/XML_XPath/XPath/result.php' : /php/pear/XML_XPath/XPath/result.php(508): $this = null; Expected result: ---------------- Solutions: The assignment to $this occurs mostly inside constructors (<Your_Package_Name>()). You should provide an static factory() or singleton() method for this. To provide backwards compatibility you should work around the affected code pieces. This can be done by a version check: if (version_compare(phpversion(), "5.0.0") == -1) { // assign factoried method to this for PHP 4 // $this =& <Your_Package_Name>::factory(); $this =& <Your_Package_Name>::singleton(); } else { // error handling for PHP5 // user has to use the factory()/singleton() method }

Dear package maintainer, The package XML_XPath makes use of the assignement of new values to $this. This methodis possible in PHP 4 but will throw an error with PHP 5 . The same bug was there in phpDocumentor but now it's been solved in 1.3.10 version. Please try to fix this. With kind regards, Amol Dhormale
