You could use header. Something like this:
你可以使用header. 像这样的东西：
if ($member == $notmember)
header("Location: index.php?option=com_jumi&view=application&fileid=6&Itemid=174");
else
header("Location: index.php?option=com_jumi&view=application&fileid=6&Itemid=124");
If after the else, you have more code, you should use exit()in order to prevent of your code to keep executing.
如果在 之后else，你有更多的代码，你应该使用 exit()以防止你的代码继续执行。
Have a look at the PHP official website. And especially take notice to the following:
看看 PHP 官方网站。尤其要注意以下几点：
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.
请记住，header() 必须在发送任何实际输出之前调用，无论是通过普通的 HTML 标记、文件中的空行还是来自 PHP。

You can use header():
您可以使用标题（）：
<?php
if ($member == $notmember) {
header("Location: http://xx.com");
exit;
} else {
header("Location: http://yy.com");
exit;
}
?>
Don't forget exit, otherwise the rest of you php script will be executed.
不要忘记exit，否则将执行其余的 php 脚本。
For more information about the header function see: http://php.net/manual/en/function.header.php

if( $member == $notmember) // use TWO equals signs, otherwise you're just assigning
header("Location: index.php.......");
else
header("Location: index.php.......");
exit; // stop script execution
