hi,

anyone i know who trys to test a variable do it this way:
for Example a URL-Submitted value:
(http://localhost/somephp.php?variable=0 dont works)
(http://localhost/somephp.php?variable=1 works)
(http://localhost/somephp.php?variable=2 works)

Global $variable;
if ($variable)
{
 echo "Variable Exist";
} else { echo "Variable dont Exist"; }

You perhaps use it too ...
the problem is :) if the variable is value anythings
fine til the point the variable-value ist zero ... thats
the point the variable exist nomore ...
only way to proof the existens is

if (strlen($variable)!=0) echo "variable exist";

i think thats a bug ....
