New Comment:
Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.

Description:
------------
After setting up PHP4.3.10 my application stoped working with error
message saying about error in one of PEAR files.
After looking into code that caused error I figured out a very strange
thing: the array_keys function gets as parameter a valid array but
returns NULL. I tried to reproduce the bug without using PEAR files but
didn't succeed. So I will describe the issue using PEAR code.
File: PEAR/DB/dataobject.php (version 1.7.2) (DB_DataObject PEAR
package)
P.S. I have no Zend debuger/optimizer/.... or any 3rd party extensions
installed
php -v result:
C:\wwwroot\bug>php -v
PHP 4.3.10 (cgi-fcgi) (built: Dec 14 2004 17:47:59)

Reproduce code:
---------------
795 if (is_object($from)) {
796 $table = $from->__table;
797 $from = array_keys($from->table());
798 }
$from->table() returns a valid array , but $from after assignment
becomes NULL.
If we modidfy the code in the following way:
795 if (is_object($from)) {
796 $table = $from->__table;
$tmp = $from->table();
var_dump($tmp);
797 $from = array_keys($tmp);
var_dump($from)
die('theend');
798 }
the result will be:
array(2) {
["id"]=>
int(129)
["name"]=>
int(2)
}
NULL
theend
moreover if we modify the code in another way:
if (is_object($from)) {
$table = $from->__table;
$tmp = $from->table();
$from = null;
$from = array_keys($tmp);
}
PHP crashes and Windows offers to send a report to Bill Gates :)
