PHP Redirect 301 Permanently

Sometimes you might want to redirect your visitors to a new URL address. This article will show you how to make a PHP redirect using the 301 “moved permanently” redirection. This is the one you should use as it is the most search engine friendly. Like the name suggests, PHP redirect tells the browser (or a search engine bot) that the page has been permanently moved to a new location.

PHP Redirect Code

To redirect people and robots to a new location use this PHP redirecting code:

header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.New-Website.com");

You could skip the 301 Moved Permanently tag and use just:

header("Location: http://www.New-Website.com");

But this would result in a “302 Moved Temporarily” redirect instead of a 301 one. This should be avoided as permanent redirects are more search engine friendly and should be used where possible.

You can enter any sub-page for the location, this PHP code will redirect users to the test.php sub-page of your website:

header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.New-Website.com/test.php");

It is important that you don’t have any other code (including empty rows and spaces) before the above PHP redirect code. If you do you will get a nice headers already sent notice from PHP and the redirect will not work.

That’s it! Enjoy redirecting PHP pages.

How to install git on Red Hat Linux / Cent OS

Git is dependent on the follow libraries, make sure they are installed.

Code:
yum install zlib-devel
yum install openssl-devel
yum install perl
yum install cpio
yum install expat-devel
yum install gettext-devel

Curl will need to be installed from source. The current version from Red Hat/Cent OS doesn’t work correctly with Git.

Code:
wget http://curl.haxx.se/download/curl-7.18.0.tar.gz
tar xzvf curl-7.18.0.tar.gz
cd curl-7.18.0
./configure
make
make install

Next, make sure /usr/local/lib is in your ld.so.conf, this is required for git-http-push to correctly link up to the Curl version you are installing.

Code:
vi /etc/ld.so.conf

(Insert the following)
/usr/local/lib

Save the file, then run:
ldconfig

Now download and install Git

Code:
wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.gz
tar xzvf git-latest.tar.gz
cd git-date
autoconf
./configure --with-curl=/usr/local
make
make install

FOSFacebookBundle: “The Facebook user could not be retrieved from the session.” (a possible solution)

If you get the message below when you try to connect to your site via Facebook Connect,

The Facebook user could not be retrieved from the session.

You just need to change your localhost URL on your own hosts file that Facebook can give you cookie permission of which is blocked by default for localhost development.
To do that, just add a new line below to your hosts file;
127.0.0.1 localhost.local
And do not forget to change your application settings at developer.facebook.com to allow your new application URL http://localhost.local/your_app/.

Thank you for reading.

Overall Summary of my First Week on the New Job at Enuygun.Com

Enuygun.com

The end of the week showed up for me and I feel like writing about my firs week at Enuygun.Com. Firstly, I haven’t learn much about the company but I think its a kind of new but successful company. I’m a senior software developer here and we’re going to build applications, services, mobile applications and an affiliate system for all we can share the growth. We are using Symfony2 as PHP framework of which I had no idea at the beginning. For the first 2 days it was like what a horrible structure that everything is bundled and you need to create new bundle to use the other bundle. At least, that’s what I think it was. After a huge concentration on research and watching some tutorials about Symfony, I now can say that, it might be the best framework to be used to develop easily implemented bundles that could be used by many applications. It’s not that none of the other frameworks don’t have the ability but it is for me now that when I think about bundled or plug in based system development is Symfony.

All in all, although I did not have any clue about the technology that they have been using till now, I think I made a grate performance to figure out what is what, why it is used and how I can use things while I have my developer hat put-on. So, the thing is, Enuygun.com is totally new for me and I feel like I’m going to be successful as I used to be on the previous companies. But I should note that, getting a job far away from your home is not the best choice. But it was a quick shoot. I hope I made a good decision.

Thank you for reading.

Compressing Stylesheets with PHP

If you wonder what else you can do to compress your files, I found a PHP code of which is written by a German coder that is shared on another blog. Basicaly it removes spaces and back slashes to minify the included files and compress them using ob_gzhandler.

  header('Content-type: text/css');
  ob_start("compress");
  function compress($buffer) {
    /* remove comments */
    $buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer);
    /* remove tabs, spaces, newlines, etc. */
    $buffer = str_replace(array("\r\n", "\r", "\n", "\t", '  ', '    ', '    '), '', $buffer);
    return $buffer;
  }

  /* your css files */
  include('master.css');
  include('typography.css');
  include('grid.css');
  include('print.css');
  include('handheld.css');

  ob_end_flush();

Compressing Web Site Contents, Scripts and Stylesheets

Today I wonder how I could minify my javascript files and do a server side compression to minimize the cost of loading web site requred javasript and stylesheet files. Where to begin… I’ll start from Apache Server configuration information for server side compression and finish with YUI Compressor that helps you to minify your script files as you should have seen those files ending with “your_script_file.min.js”. If you are using Apache Server, you might have Deflate Module installed with your Apache installation. What you need to load this module while your your server starts is to configure your apache configuration file.

LoadModule deflate_module modules/mod_deflate.so

And if you have access to the httpd.conf then you can add following lines to it.

<Location />
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/x-js text/css
</Location>

If not; you should specify the initialization line into your htaccess file.

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/css text/plain text/javascript text/xml application/xhtml+xml application/x-httpd-php
</IfModule>

You might have problems to compress javascript files which has different mime types. Then, you can use followig configuration.

AddOutputFilterByType DEFLATE application/x-javascript

That will do. Now, I will introduce YUI Compressor. YUI Compressor is one of Yahoo developer team product that you can download from here. If you have dowloaded the YUI Compressor built from the site that I shared above, what you should do to compress your file is:

java -jar yuicompressor-x.y.z.jar myfile.js -o myfile-min.js --charset utf-8

Where, x, y and z are the version number of the YUI Compressor download. Also you can find more information about YUI Compressor at http://developer.yahoo.com/yui/compressor/#work

Thank you for reading, I hope this will help some of you guys.
