getting around the undefined index


I have not found a satisfactory way of doing this yet!!!!


$text = $_REQUEST['text_size'];
if ($text) {
echo $text;
}


I send the $text_size variable to the browser with lines like...

<a href="<? $_SERVER['PHP_SELF']; ?>?text_size=small" class="size1"
id="one">A</a>


When the page initially loads I get a undefined index error as it does not
exist but is there a way of wrapping in in a switch statement or funtion so
the variable is only used when $_REQUEST['text_size']; actually exists.
