where <code>$location</code> is the path after the domain, starting with <code>/</code>.

My preferred method for reloading the same page is $_SERVER['PHP_SELF']

<pre><code>header('Location: '.$_SERVER['PHP_SELF']);
die;
</code></pre>

Don't forget to die or exit after your header();

Edit: (Thanks @RafaelBarros )

If the query string is also necessary, use 

<pre><code>header('Location:'.$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING']);
die;
</code></pre>

Edit: (thanks @HugoDelsing)

When htaccess url manipulation is in play the value of $_SERVER['PHP_SELF'] may take you to the wrong place. In that case the correct url data will be in <code>$_SERVER['REQUEST_URI']</code> for your redirect, which can look like Nabil's answer below:

<pre><code>header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;
</code></pre>

You can also use $_SERVER[REQUEST_URI] to assign the correct value to <code>$_SERVER['PHP_SELF']</code> if desired. This can help if you use a redirect function heavily and you don't want to change it. Just set the correct vale in your request handler like this:

<pre><code>$_SERVER['PHP_SELF'] = 'https://sample.com/controller/etc';
</code></pre>

blocks|key|514677|text|另一个优雅的例子是|type|unstyled|depth|inlineStyleRanges|entityRanges|data|514678|header("Location:+http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");

To really be universal, I'm using this:

<pre><code>$protocol = (!empty($_SERVER['HTTPS']) &amp;&amp; $_SERVER['HTTPS'] !== 'off' 
 || $_SERVER['SERVER_PORT'] == 443) ? 'https://' : 'http://';
header('Location: '.$protocol.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
exit;
</code></pre>

I like <code>$_SERVER['REQUEST_URI']</code> because it respects mod_rewrite and/or any GET variables.

Simple line below works just fine:

How can I redirect to the same page using PHP?

For example, locally my web address is:

<pre><code>http://localhost/myweb/index.php
</code></pre>

How can I redirect within my website to another page, say:

<pre><code>header("Location: clients.php");
</code></pre>

I know this might be wrong, but do I really need to put the whole thing? What if later it is not <code>http://localhost/</code>?

Is there a way to do something like this? Also, I have a lot of code and then at the end after it is done processing some code... I am attempting to redirect using that. Is that OK?
