Doxygen在记录PHP时出现奇怪的问题，如果

//! Set default ::$action for called controller. If no action is called, default (index) will be set.
$action = isset($_GET[ \'action\']) ? $_GET[ \'action\'] : \'index\';

if ($action) {
    echo \'something 1\';
}else{
    echo \'something 2\';
}

//! Set default ::$action2 for called controller. If no action is called, default (index) will be set.
$action2 = isset($_GET[ \'action\']) ? $_GET[ \'action\'] : \'index\';

//! Set default ::$action3 for called controller. If no action is called, default (index) will be set.
$action3 = isset($_GET[ \'action\']) ? $_GET[ \'action\'] : \'index\';
