problems using $HTTP_GET_VARS

hi! i have got a problem with php3 on my redhat (6.2) linux system. i am running the newest rpm versions of apache and mysql, and i have built and installed php3 as a DSO with mysql support enabled. everything seems to work fine; but i have encountered one strange thing: when i try to access the parameters passed from a form, i keep getting this message: "Warning: Variable passed to each() is not an array or object in /home/httpd/html/sourceforge/www/testphp.php on line 11" ---- this happens when i try, for instance, the following: while(list($k,$v) = each ($HTTP_GET_VARS)) { printf("name %s, wert %s", $k, $v); } - it just won't work... the funny thing is that accessing the params by their names works! (i mean, using $foo for <input name="foo">). do you have a clue what's going wrong here? i have a feeling that it's something about the include-path, but apart from that, i am totally lost. what i have is (in httpd.conf) <Directory /> php3_include_path /home/httpd/html/sourceforge/www/include:/usr/local/include/php:. </Directory> - i'd reallly appreciate any comments, and sorry for the stupid question, but obviously it's so foolish a problem that it's not even mentioned in the FAQs... my best regards, karin kosina, software competence center hagenberg
