正则表达式跨多行提取数据

Question

我需要捕获每个案例定义，然后捕获相关的php文件名。我已经成功地将这个表达式用于单行项目

$re = 'case [\"|\'](.*?)[\"|\'].*=[\s|\"|\'](.*?\.php)';

我正在使用的字符串是：

 //--- the following 2 lines are captured
 case 'course_leaders'           : $page='admin/p-members/email-leaders.php'; break;
 case 'courseDifferences'        : $page='admin/p-events/diff.php'; break;

 //--- the following two cases are not processed/captured
 case 'course_leaders_report'    :
             wp_enqueue_script( 'crsLeaders'
                               , plugin_dir_url(__FILE__).'admin/js/jquery.tablesorter.min.js'
                               , array('jquery') );
             $page='admin/p-events/leaders-report.php';
             break;
 case 'course_listing'           :
             wp_enqueue_script('courseListingDataTables' //--- name
                 //--- location of js file relative to this file
                , plugin_dir_url(__FILE__).'admin/js/DataTables/datatables.min.js'
                , array('jquery') //--- use jquery
             );
             wp_enqueue_script( 'jquery' );
             $page='admin/p-events/list-report.php';
             break;

 //--- this is being captured
 case 'course_program' : $page='admin/p-program/courseProgram.php'; break;

没有捕获course_leaders_report和course_listing（来自regexp101.com）。
