$_POST should be an array - not $var !

Hi.

This seems nice example..

but before using this function..first do check that that var is an array.
i.e. if u know that sometimes this vars will not have any key-value
sometimes.. then...before using foreach..check whether this is array ot
not..else it will giv error of "invalid arguments in for each loop" or
similar...

Thanks
