First of all give a name to your select  Then do    lt select name  my select  gt   lt option value  1   lt       POST  my select       1     selected       gt  gt Yes lt  options gt   lt option value  2   lt       POST  my select       2     selected       gt  gt No lt  options gt   lt option value  3   lt       POST  my select       3     selected       gt  gt Fine lt  options gt   lt  select gt    What that does is check if what was selected is the same for each and when its found echo  selected

Programmers are lazy   er    efficient    I d do it like so    lt select gt  lt  php      the key   1     or whatever you want     foreach array          1   gt   Yes           2   gt   No           3   gt   Fine         as  key   gt   val             gt  lt option value   lt  php echo  key    gt   lt  php             if  key   the key echo   selected  selected              gt  gt  lt  php echo  val    gt  lt  option gt  lt  php         gt  lt  select gt   lt input type  text  value    name  name  gt   lt input type  submit  value  go  name  go  gt

I suppose that you are using an array to create your select form input   In that case  use an array    lt  php      selected   array    REQUEST  yesnofine     gt   selected  selected           fields   array 1   gt   Yes   2   gt   No   3   gt   Fine       gt     lt select name    yesnofine  gt    lt  php foreach   fields as  k   gt   v     gt     lt option value   lt  php echo  k   gt    lt  php  print  selected  k     gt  gt  lt  php echo  v   gt  lt  options gt    lt  php endforeach    gt    lt  select gt    If not  you may just unroll the above loop  and still use an array     lt option value  1   lt  php  print  selected  k     gt  gt Yes lt  options gt    lt option value  2   lt  php  print  selected  k     gt  gt No lt  options gt    lt option value  3   lt  php  print  selected  k     gt  gt Fine lt  options gt    Notes that I don t know    how you are naming your input  so I made up a name for it   which way you are handling your form input on server side  I used   REQUEST     You will have to adapt the code to match requirements of the framework you are using  if any   Also  it is customary in many frameworks to use the alternative syntax in view dedicated scripts

This is the solution that I ve came up with    lt form name    form1  id    form1  action       method    post  gt     lt select name    DropDownList1  id    DropDownList1  gt   lt  php  arr   array  Yes    No    Fine        create array so looping is easier for   i   1   i  lt   3   i        loop starts at first value and ends at last value      selected          keep selected at nothing   if  isset    POST  go          check if form was submitted         if    POST  DropDownList1       i      if the value of the dropdownlist is equal to the looped variable              selected    selected    selected       if is equal  set selected    selected                 note  if value is not equal  selected stays defaulted to nothing as explained earlier   echo   lt option value         i          selected     gt      arr  i      lt  option gt       echo the option element to the page using the  selected variable     gt     lt  select gt   lt  -- finish the form in html -- gt     lt input type  text  value    name  name  gt     lt input type  submit  value  go  name  go  gt   lt  form gt    The code I have works as long as the values are integers in some numeric order   ascending or descending    What it does is starts the dropdownlist in html  and adds each option element in php code  It will not work if you have random values though  i e  1  4  2  7  6  Each value must be unique
