#46570 [Opn->Bgs]: __get() behaves unpredictably

ID: 46570 Updated by: lbarnaud@php.net Reported By: ms419 at freezone dot co dot uk -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Debian PHP Version: 5.2.6 New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. This is because you are fetching $this->repository in __get(). This calls __get() inside of __get(), which returns null. Use $this->values[$name] instead in __get().

Some of the attributes are the results of expressions which I only want to evaluate when the attribute is accessed for the first time. The __get() function seems perfect for this. One attribute is "repository" - its value should be the result of an expression, concatenated with a slash character and another attribute ("name"), if "name" is not null. When "name" is not null, the first time "repository" is accessed, __get() returns the result of the expression, without anything concatenated. The second time "repository" is accessed, __get() returns just a slash character and "name", without the result of the expression. Reproduce code: --------------- http://cgi.sfu.ca/~jdbates/tmp/php/200811130/test.phps Expected result: ---------------- ket% php test.php string(9) "some expr/name" string(4) "some expr/name" ket% Actual result: -------------- ket% php test.php string(9) "some expr" string(4) "/name" ket% ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46570&edit=1
