Status: Bogus
Bug Type: DOM XML related
Operating System: MAC OS X, AMD Altholon, SOLARIS
PHP Version: 4.3.8
New Comment:
hmm, i'm not sure this is a 'bogus' bug, there is no documentation on
this little 'free' function (although is certainly works)...so perhaps
the 'bug' is more of a documentation thing (i.e. i did not know the
'free' function exsisted)

use $dd->free() instead of unset($dd).

Description:
------------
I know this issue has been resolved in PHP 5.0 using
DomDocument::loadXML, BUT in non 5.0 versions, the loading of string
XML (memmory) bits has some serious garbage collection
problems...namely repeated calls to domxml_open_mem eats the memmory of
the system alive....
unsetting variables has no effect....
Reproduce code:
---------------
$tt = '<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<ff>
<rrr>555</rrr>
<rrrr>5555</rrrr>
<rrrrr>55555</rrrrr>
<rrrrrr>555555</rrrrrr>
<rrrrrrr>5555555</rrrrrrr>
<rrrrrrrr>55555555</rrrrrrrr>
<rrrrrrrrr>555555555</rrrrrrrrr>
</ff>
</data>';
for($i=0;$i<100000;$i++){
$dd = domxml_open_mem($tt);
unset($dd);
}
Expected result:
----------------
not to have the system memory jump by Megabytes...if the loop is left
for longer it will eventually chew all resources
Actual result:
--------------
massive eating of memmory
