表单选项值，其中包含php代码

How can I add PHP code to a form option value. The PHP code is actually part of a Wordpress plugin that serves a certain function. When you click on a certain value, I want an option to show up (using the PHP code).

<option value="<?php 
    echo wpws_get_content('http://eoddata.com/stockquote/NASDAQ/GOOG.htm',
                          '#ctl00_cph1_cc1_ct1' ); 
?>">Chart</option>

Echo the whole form out using PHP. This makes sure that the PHP has loaded first before it changes the value.
