尝试使用php重新加载页面

Question

I am trying to use an image as a button to refresh pages on a website. The footer (a php include) is currently using this code to refresh each page:

<a href="javascript:void(0);" onClick="javascript: location.reload(true);" name="Reset page" title="Reset page"><img src="/images/refresh.png"></a>

which of course works. BUT I would like to improve it. Essentially, it would be something like this:

onClick="javascript: window.location.href='abcd.html';"

BUT I need it to work dynamically because I'm using php pages. So I was thinking this would work:

<a href="javascript:void(0);" onClick="javascript: window.location.href='<? php $_SERVER['REQUEST_URI'] ?>';" name="Reset page" title="Reset page"><img src="/images/refresh.png"></a>

But it doesn't work. Any ideas? I'm using <? php $_SERVER['REQUEST_URI'] ?> wrong (obviously), so, any ideas for assistance? Thank you for any help!

Problem noticed is you have a space between <? and php in the following line:

<a href="javascript:void(0);" onClick="javascript: window.location.href='<? php $_SERVER['REQUEST_URI'] ?>';" name="Reset page" title="Reset page"><img src="/images/refresh.png"></a>

Also you want to echo out the value for $_SERVER['REQUEST_URI']. You are just calling $_SERVER['REQUEST_URI']. Also as @NickCoons pointed out when using the echo construct you need to add a semi-colon i.e. echo $_SERVER['REQUEST_URI'];.

Try the following:

<a href="javascript:void(0);" onClick="javascript: window.location.href='<?php echo $_SERVER['REQUEST_URI']; ?>';" name="Reset page" title="Reset page"><img src="/images/refresh.png"></a>
