that error is because a for loop is not meant to be appended to an string — Joe, Nov 09 '13 at 06:19
Any good reason to use for loop in a echo ? [PHP : how to use foreach loop inside an echo statement?](http://stackoverflow.com/questions/6197581/php-how-to-use-foreach-loop-inside-an-echo-statement) — Uours, Nov 09 '13 at 06:22
its not possible to use select statement with one statement for echo — Anshul Parashar, Nov 09 '13 at 06:32
This is not python my friend, where you can say something like "\n".join(["
"+html+"
" for html in contents]) which resolves to a single, concatenate-able string. — Jorge Orpinel Pérez, Apr 19 '14 at 23:44

id recommend either building your options first then appending them to your echo string like so:

$optionString = '';
for ( $i = $data['timeh']; $i <=24; $i++ ){
 $optionString .= "<option ...>".$i."</option>";
}

or making 2 echos to open and close the select and a loop with the option echo in the middle eg

echo "<select ...>";

for ( $i = $data['timeh']; $i <=24; $i++ ){
 echo "<option ...>".$i."</option>";
}

echo "</select>";

sorry but i need this html part in one variable – chirag Nov 09 '13 at 06:22
then i would set a variable like `$htmlString`... set it to your opening select string. use the above for loop to append the options. after the loop append the closing select tag - and echo it all out at once – Joe Nov 09 '13 at 06:25

@chirag Then replace the first `echo` with `$string=`, and the remaining ones with `$string.=`. Then `$string` will contain everything in one variable, which can be `echo`'d. – Willem Renzema Nov 09 '13 at 06:25

try this..

echo "<select class='formfield_select'   name='return_pickuptime_hh' id='rhh' >
                  <option value='' selected='selected' >Hour</option>
                  ";


                  for($i=0;$i<=24;$i++) 
                  {

                  echo "<option value=$i>$i</option>";

                   } 

                echo "</select>";
