Answer 2

You need to add another tag that is blank.

Working example: http://jsfiddle.net/XYSXA/

<select name="mySelect" id="mySelect" class="select"  onchange="if(this.options[this.selectedIndex].value != ''){window.top.location.href=this.options[this.selectedIndex].value}">
    <option value=""></option>
    <option value="english.php">English</option>
    <option value="french.php">French</option>
    <option value="spanish.php">Spanish</option>
</select>​

This way none of the options will be selected by default.

Alternatively, you may use the set the attribute selected inside one of the opening <option> tags to specify which language should be selected by default. Example selecting French by default:

<select name="mySelect" id="mySelect" class="select"  onchange="if(this.options[this.selectedIndex].value != ''){window.top.location.href=this.options[this.selectedIndex].value}">
    <option value=""></option>
    <option value="english.php">English</option>
    <option value="french.php" selected>French</option>
    <option value="spanish.php">Spanish</option>
</select>​

Answer 3

<?
$file=basename($_SERVER['PHP_SELF'],".php");
$file=ucwords($file);
?>
<option value="french.php" <?=($file=="French")?" selected='selected'":""?>>French</option>

I m assuming that you're using the pattern like French for french.php, Spanish For spanish.php,etc
