As mellowsoon suggest, you might consider this approach:

required = array('myvar' => "defaultValue1", 'foo' => "value2", 'bar' => "value3", 'baz' => "value4");
$missing = array_diff($required, array_keys($_GET));
foreach($missing as $key => $default  ) {
    $_GET[$key] = $default  ;
}

You put the default values and set the not recieved parameters to a default value :)
