Previous Comments: ------------------------------------------------------------------------ [2014-05-16 19:54:57] pmoroney at name dot com Description: ------------ When an error handler is called because of a undefined property and the error handler references a different object property that doesn't exist, even in an isset(), the original property gets replaced by the new property in the operation that was being performed. I ran a git bisect to find the commit that introduced the error and found the following commit: commit 0c6d903ce7615a7197cb997d67d98058c3ec5d6a Author: Stanislav Malyshev <stas@php.net> Date: Mon Feb 18 20:56:02 2013 -0800 fix bug #49348 - issue notice on get_property_ptr_ptr when used for read Test script: --------------- <?php function err_handler() { $s = new StdClass(); isset($s->bad); } set_error_handler('err_handler'); $f->good += 5 ; var_export($f); if(isset($f->bad)) exit(1); else exit(0); Expected result: ---------------- stdClass::__set_state(array( 'bad' => 5, )) With an Exit value of 1 Actual result: -------------- stdClass::__set_state(array( 'good' => 5, )) With an Exit value of 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67294&edit=1
