Answer / mishra ashutosh
i am assuming that you want to test whether a no is prime or not.
$no=123;//lets say, u can take this value form also using $_POST or $_GET
$flag=0;
for($i=2;$i<$no;++$i){
if($no%$i==0){
$flag=1;
break;
}
}
if($flag==1)
echo "$no is not a Prime No" ;
else
echo "$no is a Prime No" ;
