The easiest way I can think of is the following   lt  php   selection   array  PHP    ASP    echo   lt select gt         lt option value  quot 0 quot  gt Please Select Option lt  option gt     foreach   selection as  selection         selected     options     selection     quot selected quot     quot  quot       echo   lt option    selected   value  quot    selection   quot  gt    selection   lt  option gt       echo   lt  select gt     The code basically places all of your options in an array which are called upon in the foreach loop  The loop checks to see if your  options variable matches the current selection it s on  if it s a match then  selected will   selected  if not then it is set as blank  Finally the option tag is returned containing the selection from the array and if that particular selection is equal to your  options variable  it s set as the selected option
