redirect 重定向的通用语法为:redirect(url,params=array(),delay=0,msg='')
用法:
protected function redirect($url,$params=array(),$delay=0,$msg='') {
$url = U($url,$params);
redirect($url,$delay,$msg);
}
源码:参见框架内置的functions.php文件
function
redirect(
$url
,
$time
=0,
$msg
=
''
) {
//多行URL地址支持
$url
=
str_replace
(
array
(
"\n"
,
"\r"
),
''
,
$url
);
if
(
empty
(
$msg
))
$msg
=
"系统将在{$time}秒之后自动跳转到{$url}！"
;
if
(!headers_sent()) {
// redirect
if
(0 ===
$time
) {
