    php
    $low=$_POST['num']; // low variable for starting range
    $high=$_POST['num1']; // high variable for ending range
    while($low<$high)
    { $flag=0;
    for($i=2;$i<$low;$i++)
    { if($low%$i==0)
    {$flag=1;
    break;
    }
    }
    if($flag==0)
    echo"
    $low is an prime number";
    else
    echo"
    $low is not a prime number";
    ++$low;
    }
