Put your if condition out of quotes

for($i=0;$i<21;$i++)
{
   $selected=($i==5) ? 'selected' : '';
   $html.="<option value='$i'  $selected>". $i ."</option>";

}

Will fail due to improper quoting. May also be wrong depending on desired HTML version/adherence.

@ignacio: Where is the improper quotes?

You had the second line in single quotes before.

You're line is incorrect. Use this instead:

$html .= '<option value="' . $i . '"' . ( $i==5 ? ' selected="selected"' : '' ) . '>' . $i . '</option>';

I'm making use of the ternary comparison operator.

here is the problem

$html.='<option value="$i" if($i==5) { selected } >'. $i .'</option>';

SolutionL

$html.="<option value=\"$i\" ".($i==5? "selected": ""). "$i </option>";
