php html 常见页面跳转的多个实用方法
在php编写中有时会用户页面跳转，在这里收集了几种不错的跳转方法，可以用到。 无 也就是用PHP的HEADER函数。PHP里的HEADER函数的作用就是向浏览器发出由HTTP协议规定的本来应该通过WEB服务器的控制指令，例如声明返回信息的类型("Context-type: xxx/xxx")，
在php编写中有时会用户页面跳转，在这里收集了几种不错的跳转方法，可以用到。
也就是用PHP的HEADER函数。PHP里的HEADER函数的作用就是向浏览器发出由HTTP协议规定的本来应该通过WEB服务器的控制指令，例如声明返回信息的类型("Context-type: xxx/xxx")，页面的属性("No cache", "Expire")等等。
用HTTP头信息重定向到另外一个页面的方法如下：
<?
if (isset($url))
{
Header("HTTP/1.1 303 See Other");
Header("Location: $url");
exit; //from www.ruonu.com
}
?> 用HTML标记，就是用META的REFRESH标记，举例如下： <? if (!isset($url)) exit;?> <HTML> <HEAD> <META HTTP-EQUIV="REFRESH" CONTENT="5; URL=<? echo $url;?>> </HEAD> <BODY> </BODY> </HTML>
<? $url="http://www.ruonu.com"; echo "<!--<scrīpt LANGUAGE="Javascrīpt">"; echo "location.href='$url'"; echo "</scrīpt>-->"; ?>
echo "< meta http-equiv=\\"Refresh\\" content=\\"秒数; url=跳转的文件或地址\\" > "; 其中:XX是秒数,0为立即跳转.refresh 是刷新的意思.Url 是要跳转到的页面.
echo '<script>url="submit.php";window.location.href=url;</script>';
利用script实现,所不同的是使用 open 语句.且可以限制原窗口还是父窗口,子窗口或者新窗口.
<script>url="submit.php";window.open(\'url,\'\',\'_self\');</script>
其中 更改\'_self\' 就可以实现跳转限制原窗口还是父窗口,子窗口或者新窗口.第七种:利用php自带函数发送头部信息
header("Location: Url");
速度最快,功能强大...但是有个问题必须指出:如果在使用这个函数前已经有html输出,哪怕是一个空格.那么在页顶会显示错误信息..
