for ($i=0;$i<$fc;$i++)
{

$var = "a$i";
i have to retrieve a value from the database where a column value should be $$var.But there is no value for $$var.
Moreover,if i dont use any button submission and if there is no such thing like before and after submission but the variable is just used in the second page,there is being some value for $$var.

Please help me with this.Hope this is understandable.

Thanks,
Shara.
