在php中301重定向實(shí)現(xiàn)方法很簡(jiǎn)單我們只要簡(jiǎn)單的利用header發(fā)送301狀態(tài)代碼，然后再用header進(jìn)行跳轉(zhuǎn)，效果與apache,iis,nginx都是一樣的效果哦。
一:更推薦這種方法,因?yàn)樗梢园裩ttp://www.ythuaji.com.cn原來(lái)所有的url都轉(zhuǎn)到http://zzvips.com新的地址上
代碼如下

<?php$the_host = $_SERVER['HTTP_HOST'];$request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';if($the_host == 'www.ythuaji.com.cn'){header('HTTP/1.1 301 Moved Permanently');header('Location: http://zzvips.com'.$request_uri);//}?> |
二:單頁(yè)多站的Php301重定向代碼,www.ythuaji.com.cn和zzvips.com則301到index.php上,zzvips.com則301到www.ythuaji.com.cn上,否則轉(zhuǎn)到錯(cuò)誤頁(yè)

跳轉(zhuǎn)要注意以下幾點(diǎn),有助于解決一些新手經(jīng)常遇到的問(wèn)題
1、location和“:”號(hào)間不能有空格，否則會(huì)出錯(cuò)。
2、在用header前不能有任何的輸出。
3、header后的PHP代碼還會(huì)被執(zhí)行。
以上就是,對(duì)php 301重定向跳轉(zhuǎn)的資料整理，希望能幫助php 開(kāi)發(fā)的同學(xué)。
