测试环境:Windows Server2003 + PHP5.3.5_TS + Apache2.2.19

新建1.php,放在localhot根目录下,文件内容如下:

 

set_error_handler( function() {
             echo '出错了';
        });
set_exception_handler( function() {
             echo '出错了';
        });
error_reporting( E_ALL & ~ E_NOTICE);
// 一段html文本
$html = '

<script>swfobject.embedSWF("/flash/player.swf", "div_D65EEBE0-2955-A608-27A6-CB5713579FC2", "500", "300", "9.0.0","/flash/expressInstall.swf", {file: "/videos/2011/12/26/15/3F5F5136-0200-A646-5B48-C5C4D9ED1C3B.flv"}, {wmode:"opaque",allowfullscreen:"true", allowscriptaccess:"always"}, {id: "player_D65EEBE0-2955-A608-27A6-CB5713579FC2",wmode:"opaque"});</script>';
// 一个去除script脚本块的正则
$reg = '#<script>]*>(((?!(?<![\'""])<\/?script>(?![\'""]))[\s\S])*)</script>#i';
// 正则替换,去除脚本,执行此句的时候杀死了当前的http连接,用Fiddler监控发现此连接的状态码为0(网上没有搜索到状态码为0表示什么意思)
$html=  preg_replace( $reg, '',  $html);
echo  $html;
?>

 用Chrome浏览器,打开http://localhost/1.php,提示:错误 324 (net::ERR_EMPTY_RESPONSE):服务器已断开连接,且未发送任何数据。
