#30321 [NEW]: serializing a DOMDocument object doesn't work

From: matthias dot hoseit at comline dot de Operating system: Windows 2000, Apache 1.3.31 PHP version: 5.0.2 PHP Bug Type: DOM XML related Bug description: serializing a DOMDocument object doesn't work Description: ------------ The function serialize() doesn't work with a DOMDocument object. After you've serialized and unserialized an object of DOMDocument the unserialized object seems to be empty (The object knows that it is a DOMDocument Object, but all data is lost). Reproduce code: --------------- <?PHP //----------------------------------------------Building a working DOMDocument----------------------------------- //create new DOMDocument $domDoc1 = new DOMDocument(); //create some elements $rootElement = $domDoc1->createElement("Element1"); $element2 = $domDoc1->createElement("Element2", "Value2"); //adding element to root $rootElement->appendChild($element2); //adding root to DOM $domDoc1->appendChild($rootElement); //show that DOMDocument is working right now $elements1 = $domDoc1->getElementsByTagName("Element2"); foreach ($elements1 as $val) { echo "TagName = '".$val->tagName."' "; echo "Value = '".$val->nodeValue."'<br>"; } //----------------------------------------------now the strange behavior----------------------------------------- //now serialize DOMObject $serialize1 = serialize($domDoc1); //The serialized DOMObject seems to be empty echo $serialize1."<br>"; //unserialize $unserialize1 = unserialize($serialize1); //----------------------------------------------the error-------------------------------------------------------- //And now there is the error.. $unserialize1 seems to be no DOMDocument or an empty one $elements2 = $unserialize1->getElementsByTagName("Element2"); //You get the error message: Warning: Couldn't fetch DOMDocument in .... //print_r shows an empty object print_r($unserialize1); ?> Expected result: ---------------- I thought, when you unserialize a DOMDocument object you get a DOMDocument object with all data of the original one (NodeLists etc). Actual result: -------------- After unserializing a serialized DOMDocument object you get an empty DOMDocument object. -- Edit bug report at http://bugs.php.net/?id=30321&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30321&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30321&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30321&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30321&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30321&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30321&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30321&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30321&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30321&r=support Expected behavior: http://bugs.php.net/fix.php?id=30321&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30321&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30321&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30321&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30321&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30321&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30321&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30321&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30321&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30321&r=mysqlcfg
