Xdebug nor phpdbg nor Zend debuggers support this. Xdebug issue regarding this was closed with resolution "won't fix", because "In PHP, this would mean watching a specific memory location, and that can not be done in a safe way.", see https://bugs.xdebug.org/view.php?id=514 If the quote is correct, this feature request is about implementing a way in PHP core which allows to implement this feature in debuggers easier. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75659&edit=1
