PHP Bug Type: DOM XML related
Bug description: Method calls fail on DOM document objects passed as session variables
Description:
------------
Method calls fail on DOM document objects passed as session variables.
This happens whether you pass the DOM document object itself or a
reference to the object as a session variable. If you serialize and
unserialize an object reference to a DOM document object without passing
it as a session variable, it works fine:
<?php
/**
* This test shows that a reference to a DOM object can be
* serialized and unserialized and still be used.
*/
$xml = "<?xml version='1.0' ?><foo><bar>Hoot!</bar></foo>";
$foo =& domxml_open_mem($xml);
$foo = unserialize(serialize($foo));
print $foo->dump_mem();
?>
Reproduce code:
---------------
<?php
session_start();
/**
* This code tests method calls on a reference to a DOM object that
* has been passed as a session variable.
*/
if (session_is_registered('foo')) {
$_SESSION['foo']->dump_mem();
session_unregister('foo');
} else {
print "Creating reference to new DOM object as a session
variable...";
session_register('foo');
$xml = "<?xml version='1.0' ?><foo><bar>Hoot!</bar></foo>";
$_SESSION['foo'] =& domxml_open_mem($xml);
}
?>
<?php
session_start();
/**
* This code tests method calls on a DOM object that has been passed
* as a session variable.
*/
if (session_is_registered('foo')) {
$_SESSION['foo']->dump_mem();
session_unregister('foo');
} else {
print "Creating new DOM object as a session variable...";
session_register('foo');
$xml = "<?xml version='1.0' ?><foo><bar>Hoot!</bar></foo>";
$_SESSION['foo'] = domxml_open_mem($xml);
}
?>
Expected result:
----------------
Both of these scripts should print the original xml source.
Actual result:
--------------
Both fail with "Warning: dump_mem(): Underlying object missing or of
invalid type" followed by "Warning: dump_mem(): Cannot fetch DOM object"
error.
