二者區別: asp的redirect函數能夠在向客戶發送頭文件後起做用. php
<html><head></head><body> <%response.redirect "../test.asp"%> </body></html>
<html><head></head><body> <? header("location:../test.php"); ?> </body></html>
後者會報錯html
只能這樣: 緩存
<? header("location:../test.php"); ?> <html><head></head><body>...</body></html>
即header函數以前不能向客戶發送任何數據. 函數
asp中編碼
<html><head></head><body> <% response.redirect "../a.asp" response.redirect "../b.asp" %> </body></html>
結果是重定向a.asp文件. url
php文件spa
<? header("location:../a.php"); header("location:../b.php"); ?> <html><head></head><body></body></html>
發現它重定向b.php.
通常地咱們用 .net
if(...)
header("...");
else
{
...
}
可是咱們能夠簡單的用下面的方法:
if(...)
code
{ header("...");exit();} htm
還要注意的是,若是是用Unicode(UTF-8)編碼時也會出現問題,須要調整緩存設置.
