working with checkboxes

[eluser]black.Blank[/eluser]
is there any other way on how i can rewrite the following sample code?

Code:

if(in_array('sample1',$sample)
  $samp = 1;
  else if(!in_array('sample1',$sample)
  $samp = 0;

if(in_array('sample2',$sample)
  $samp2 = 1;
  else if(!in_array('sample2',$sample)
  $samp2 = 0;

if the checkbox is ticked, then the value for the corresponding field in the dbase will be 1 else 0.
