PHP Redirect Function
After form submission or a page redirect is triggered, it's commonplace to redirect the user to a different page or to the same page, formatted in a different way. Usually, you'd complete this by coding:
header('Location: destination.php');
exit();
This is a completely acceptable way to code your pages, but I prefer to use a redirect function instead. Why? It's much more readable, and quite honestly, I'm tired of writing the header('Location: ...'); code.
function redirect($url, $permanent = false) {
if($permanent) {
header('HTTP/1.1 301 Moved Permanently');
}
header('Location: '.$url);
exit();
}
This function is incredibly easy to use and saves a lot of code.
![How I Stopped WordPress Comment Spam]()
I love almost every part of being a tech blogger: learning, preaching, bantering, researching. The one part about blogging that I absolutely loathe: dealing with SPAM comments. For the past two years, my blog has registered 8,000+ SPAM comments per day. PER DAY. Bloating my database...

Client-side APIs on mobile and desktop devices are quickly providing the same APIs. Of course our mobile devices got access to some of these APIs first, but those APIs are slowly making their way to the desktop. One of those APIs is the getUserMedia API...

One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?

Scrolling animations are fun. They are fun to create and fun to use. If you are tired of bootstrapping you might find playing with scrolling animations as a nice juicy refreshment in your dry front-end development career. Let's have a look how to create animating...
Do you use a plugin to highlight and format your php code?
I’m pretty sure he uses:
http://code.google.com/p/syntaxhighlighter/
Shawn’s correct — you can go to the URL above to download the javascript and CSS files. I’m not using a WordPress plugin though — it’s easy to install on your own.
Cool, I like the features it has over my current solution that I am using.
Thanks.
Ahm… As you’re already talking about the syntaxhighlighter… Why is the little “copy code”-snippet copying code AFTER it says “the code is in your clipboard now”!? Wouldn’t it make sense to copy it before the JS alert?
Well, anyway – nice website Dave! I like it – and all the little code snippets are really nice. So simple, but helping a lot. Sometimes it’s harder to create them “the easy way”, so this really comes in handy. Thanks!
Nice and thanx
You can use highlight_string() in PHP to hightligt your code, or highlight_file()…

If you have problems with header function :
header("Location:www.google.com");you can use this line if you are fans of JavaScript ( client side ):
OR , use this line if are not ( server side ):
Sorry for my English :-)
You can run into trouble if you redirect using relative URLs. It should also be noted that
RFC1945 requires a complete absolute URI for redirection, see: http://tools.ietf.org/html/rfc1945
i have problem when i redirect the header location:-
Warning: Cannot modify header information – headers already sent by (output started at /home/adnanakh/public_html/dcncaclub.org/admin/website_insert_back1.php:3) in /home/adnanakh/public_html/dcncaclub.org/admin/website_insert_back1.php on line 18
