PHP简单HTML DOM和下拉元素选择选项

Question

I'm generating dropdown inputs with php simple html dom. I have some values from database and according them i will add 'selected' value into my select->option dom elements.

<select name="myDropDown" id="someID">
   <option value="someValue1">Value1Value</option>
   <option value="someValue2">Value2Value</option>
   <option value="someValue3">Value3Value</option>
</select>

this is the default one. i would like to add value like this, check on option 2 :

<select name="myDropDown" id="someID">
   <option value="someValue1">Value1Value</option>
   <option value="someValue2" selected>Value2Value</option>
   <option value="someValue3">Value3Value</option>
</select>

and while doing that i want to use my plugin.

<?php    
    $html = new simple_html_dom();
    $html->load('
           <select name="myDropDown" id="someID">
             <option value="someValue1">Value1Value</option>
             <option value="someValue2">Value2Value</option>
             <option value="someValue3">Value3Value</option>
           </select>
          ');
    echo $html;
?>

Everything works nicely until here. Yeah now i need to insert selected into my second option. I don't know how to do this with PHP Simple HTML DOM, or i'm missing something in the documentation : http://simplehtmldom.sourceforge.net/manual.htm#section_access

What i have tried so far and got many errors in my php section :

<?php
$html = new simple_html_dom();
   $html->load('
              <select name="myDropDown" id="someID">
                 <option value="someValue1">Value1Value</option>
                 <option value="someValue2">Value2Value</option>
                 <option value="someValue3">Value3Value</option>
              </select>
              ');
   //here's where i'm trying to reach the child nodes :    
   $ret = $html->getElementById('someID');
   $ret->children(2)->GOTTADOSOMETHINGHEREANDIREALLYDUNNO;
   echo $html;
?>

By the way, if you offer another easy way to do this, i'd appreciate.

Thank you in advance !

With minimal research you can figure this out for yourself.

$ret->children(2)->selected = true;
