There are several examples on the net, however I use this:

<?php

//functions.php

add_filter( 'widget_text', 'php_parser', 100 );
function php_parser( $html ){
 if( strpos( $html, "<"."?php" ) !== false ){
      ob_start();
      eval( "?".">".$html );
      $html = ob_get_contents();
      ob_end_clean();
 }
 return $html;   
}

?>
