hi all,
i have a small problem in php 4.0.1 which i didn't face earlier. I set
some variables. it they are not set and i try to echo them they give a
problem.
for instance,
if ($temp == 10)
{
$disp = "temp is 10";
}
echo $disp;
if temp is not 10 then when echo is processed and the output is
displayed on the browser, i get the following error:
"Warning: Undefined index: temp in testing.php on line xx"
what can be the solution for this?
thanks in advance,
gautam.
