#50793 [Opn->Ver]: Note about not being able to serialize internal objects needs clarifiaction

ID: 50793 Updated by: bjori@php.net Reported By: weirdan at gmail dot com -Status: Open +Status: Verified Bug Type: Documentation problem PHP Version: 5.3.1 New Comment: $ php -n -r '$d = new DOMDocument("1.0", "UTF-8"); $s = serialize($d); var_dump(unserialize($s)->encoding, $d->encoding);' Warning: Unknown: Invalid State Error in Command line code on line 1 NULL string(5) "UTF-8" See bug#30323 && http://svn.php.net/viewvc/phpdoc/en/trunk/reference/var/functions/seri alize.xml?r1=164053&r2=172271 I guess the simplest way to fix this is to say something along the lines of "classes that do not implement Serializable or the __sleep()/__wakeUp() functions cannot be reliably serialized"? Previous Comments: ------------------------------------------------------------------------ [2010-01-18 19:16:09] weirdan at gmail dot com Description: ------------ Manual says 'It is not possible to serialize PHP built-in objects', however some of internal classes support serialization: weirdan@virtual-debian:/home/sam/trunk$ php -r 'var_dump(phpversion()); $c = new ReflectionClass("ArrayObject"); var_dump("is internal", $c->isInternal()); $q = new ArrayObject(); var_dump(serialize($q));' string(5) "5.3.1" string(11) "is internal" bool(true) string(45) "C:11:"ArrayObject":21:{x:i:0;a:0:{};m:a:0:{}}" weirdan@virtual-debian:/home/sam/trunk$ Reproduce code: --------------- --- From manual page: function.serialize#Notes --- See description Expected result: ---------------- Explicitly list serializable/non-serializable classes for extensions enabled by default (possibly in appendix). Actual result: -------------- The note is misleading. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50793&edit=1
