header('Pragma: public');
header('Cache-Control: private');
header('Cache-Control: no-cache, must-revalidate');
header('Accept-Ranges: bytes');
header('Connection: close');
header("Content-Type: audio/mpeg");
header("Location:ftp://download:1bk3l4s3k9s2@232.2.22.22/2222/web技术开发知识库/cn_web.rmvb");

ereg("^[".chr(0xa1)."-".chr(0xff)."]+$", $str);
批量替换文本里面的超级链接
function urlParse($str = ''){
if ('' == $str) return $str;
$types = array("http", "ftp", "https");

''.htmlentities('1').htmlentities('2').''
EOPHP;
$ret = $str;
while(list(,$type) = each($types)){
$ret = preg_replace("|($type://)([^s]*)|ie ", $replace, $ret);
