PHP 5.2 and PHP 5.3 has tons of functionalities which are not provided by PHP 5.1 and PHP 5.1 is the most recent version of PHP available in CentOS 5.1 and RHEL 5.1 via updates. Also, its difficult for people to upgrade OS(s) on production servers frequently and especially if the servers are running absolutely fine, it doesn’t really make sense to upgrade just for the heck of it. One more reason for no upgrades is the OS choices provided by many hosting companies. But a lot of CMS(s) and softwares are now recommending at least PHP 5.2 for an extended feature set.

I tried a lot of repos for CentOS including RPM Fusion, RPM Forge, EPEL etc., but none of them could provide even PHP 5.2. In some corner of my mind, I had a faint idea of Remi Collet publishing updates about Remi repository. Did a quick google search and found out that PHP 5.3 is actually available in the repository

So, if you are really in need of PHP5.3 on your CentOS/RHEL 5.1 or lesser, head over to Repository Configuration Page and follow the instructions.

Note: The repository is not enabled on install (enabled=0). You need to enable it in /etc/yum.repos.d/remi.repo.

Once installed and enabled, you can update PHP, MySQL from remi repository using the following command

[root@fedora ~]$ yum update php php-* mysql-*

Warning: Drupal is still not totally compatible with PHP5.3 and if you run Drupal sites, be sure to investigate things before upgrading.

Thanks for an awesome response to the Memepress (Yahoo! Meme) Wordpress plugin. A lot of people have blogged about it and contacted me via email for enhancements. New version also fixes the bug regarding image size in posts. I have also updated the plugin to support internationalization(i18n). Now you can translate about 20 strings in your local language and you’ll have Memepress in your own language.

Turkish Translation

Huge thanks to Yalçın Erdemir for translating the plugin to Turkish

How To Translate

If you are interested in translating Memepress plugin in your language, then download the memepress.pot (POT file) and open it in your favourite text editor. Now for every string against msgid should be translated to your language and populated in quotes against msgstr. See the example below.

Before translation

#: memepress.php:37
msgid "Title"
msgstr ""

After translation

#: memepress.php:37
msgid "Title"
msgstr "_WHATEVER_TITLE_IS_WRITTEN_AS_IN_YOUR_LANGUAGE_"

Once you are done with translating all the strings, save the file and mail me at kulbirsaini25 [AT] gmail.com .

Yahoo! Meme is a new Twitter like service in testing by Yahoo!. But its much better than Twitter. It has got facility to post text, photos, video and music. The best thing about Meme is the user interface. I am just loving it. Such a clean interface I liked twitter’s web interface very much because it was not cluttered like facebook and others. But meme’s interface is much better than twitter’s interface.

As I felt hooked to it, I thought it’ll be a good idea to have wordpress widget to display latest posts from Yahoo! Meme. I took Twitter for Wordpress plugin’s source code and started modifying it to work for Yahoo! Meme and in a few hours, I managed to get a full fledged plugin for Yahoo! Meme and a few extra features and minor bug fixes as well

I have named it Memepress. For more details and latest updates about the plugin, please visit plugin homepage on wordpress. The plugin is really easy to setup and doesn’t have any dependencies and doesn’t even need to authenticate with Yahoo! Meme.

Comments/Suggestions?

Note: Yahoo! Meme is still invite only. If you need an account, send me an email using this contact form.

I was randomly browsing the internet and reading about making a website look better and I encountered ffmpeg-php. ffmpeg is a very powerful tool to record, convert and stream audio and video. Its a very rich tool almost supporting every format out there in the world. It can convert any format to any other format provided the codec. ffmpeg-php is an extension for PHP that provides a rich library to access info about audio and video files. The good thing about ffmpeg-php is that it can retrieve all info about any audio/video file subjected to the condition that the particular audio/video format is supported by your ffmpeg installation. So, now you have a clear idea that you can do wonders with audio/videos while showing them on your site

I tried some of the functionalities and they worked out of the box. Here’s is complete how to on installing ffmpeg and ffmpeg-php.

FFMPEG:

I tried installing ffmpeg from rpms provided by several Fedora repositories but after installation ffmpeg doesn’t seem to work. After several tries, I installed ffmpeg from source rpms and it worked. Below, I will describe how to install ffmpeg from source rpm.

Step 1:

Make sure that you have ‘rpmbuild’ installed by issuing

[root@bordeaux saini]# rpm -q rpmbuild [Enter]

command. If the above says that rpmbuild is not installed, then install it using yum as given below

[root@bordeaux saini]# yum install rpmbuild [Enter] (do as root)

Step 2:

Download the latest src rpm of ffmpeg from rpmfind.net. Issue the command given below

[root@bordeaux saini]# rpm -hiv ffmpeg-x.x.x.xx-xxx.src.rpm [Enter] (do as root)

Step 3:

Go to ‘/usr/src/redhat/SPECS/’ directory and issue the command given below

1
2

[root@bordeaux saini]# cd /usr/src/redhat/SPECS/ [Enter]
[root@bordeaux SPECS]# rpmbuild -ba ffmpeg.spec [Enter] (do as root)

If it gives an error like package ‘xyz’ is need by ffmpeg. Then install the package ‘xyz’ using yum as

[root@bordeaux SPECS]# yum install xyz [Enter] (do as root)

After installing the dependencies, issue the rpmbuild command ‘rpmbuild -ba ffmpeg.spec’. Now ffmpeg rpms will be build and they will be stored in ‘/usr/src/redhat/RPMS/i386/’.

Step 4:

Go the ‘/usr/src/redhat/RPMS/i386/’ (x86_64 instead of i386 if your OS is 64 bit). Install all the rpms that were built by rpmbuild.

[root@bordeaux saini]# rpm -hiv *.rpm [Enter] (do as root)

Thats it. ffmpeg is now successfully installed on your computer. Half the job is done. Now lets proceed with ffmpeg-php installation.

FFMPEG-PHP:

We will install ffmpeg-php from source bundle.

Step 1:

Make sure that ‘php-devel’ installed on your machine by issuing

[root@bordeaux saini]# rpm -q php-devel [Enter]

command. If the above command says the ‘php-devel’ is not installed, then install it using the following command.

[root@bordeaux saini]# yum install php-devel [Enter] (do as root)

Step 2:

Download the latest version of ffmpeg-php from here. Unpack the file you have downloaded.

1
2

[root@bordeaux saini]# bunzip2 -d ffmpeg-php-0.5.1.tbz2 [Enter]
[root@bordeaux saini]# tar -xvf ffmpeg-php-0.5.1.tar [Enter]

Step 3:

Issue the following command in sequence if everything goes fine.

5

[root@bordeaux saini]# cd ffmpeg-php-0.5.1 [Enter]
[root@bordeaux ffmpeg-php-0.5.1]# phpize [Enter]
[root@bordeaux ffmpeg-php-0.5.1]# ./configure [Enter]
[root@bordeaux ffmpeg-php-0.5.1]# make [Enter]
[root@bordeaux ffmpeg-php-0.5.1]# make install [Enter] (do as root)

Step 4:

Open ‘/etc/php.ini’ and add a line ‘extension=ffmpeg.so’ in the category ‘Dynamic Extensions’. For help see the image below.

Step 5:

Restart apache web server aka ‘httpd’ service by issuing the command.

[root@bordeaux saini]# service httpd restart [Enter] (do as root)

Step 6:

Write a test php file and test your ffmpeg-php installation.

phpinfo();

Save the above code in ‘info.php’ and save the file in ‘/var/www/html/’ and browse http://localhost/info.php . If you see something like this.

Then the ffmpeg-php is successfully installed on your machine. Now you can jump into the world of video manipulation via your website.

Fedora Tutorials and Videocache by Kulbir Saini.

Yesterday, I came across a library called ming for php which can do wonders while converting videos to .swf (flash), images to .swf and much more. The best thing is that ming provides wrappers in C/C++/PHP/Python/Perl/Tcl etc. So, can be used within any one of these languages. But, the damn thing drove me crazy while installing. It was very tough experience installing it as the available howtos didn’t help much. But finally I somehow managed with the installation and it worked So, I thought of writing this how to, so that anyone having the same problem can find it helpful.

Here is a complete howto on installing php-ming in Fedora. (I installed it on Fedora 7 and with php5, but howto is supposed to work with other versions as well.) Though there are rpms available for earlier versions of ming, but I wanted the latest, so installed from source.

Resources:
libming : http://www.libming.net/
PHP : http://php.net/

Step 1

First of all make sure that you have php-devel package, otherwise you will not be able to install ming at all. Do the following as root.

[root@bordeaux root]# rpm -q php-devel [Enter]

If the above command says php-devel is not installed, then fetch php-devel for your php version from here and install as given below, else proceed to step 2.

[root@bordeaux root]# rpm -hiv php-devel-5.2.2-3.i386.rpm [Enter]

Step 2

Download latest version of ming from here.

Step 3

Untar the downloaded package.

[saini@bordeaux saini]# tar -xvzf ming-0.4.0.beta5.tar.gz [Enter]

Step 4

Change directory to ‘./ming-0.4.0.beta5′ and issue ./configure and make as given below

[saini@bordeaux saini]# cd ming-0.4.0.beta5 [Enter]
[saini@bordeaux ming-0.4.0.beta5]# ./configure --enable-cXX --enable-php [Enter]
[saini@bordeaux ming-0.4.0.beta5]# make [Enter]
[root@bordeaux ming-0.4.0.beta5]# make install [Enter] (as root)

Step 5

Go to ‘./php_ext’ directory and issue ‘make’ and ‘make install’.

3

[saini@bordeaux ming-0.4.0.beta5]# cd php_ext [Enter]
[saini@bordeaux php_ext]# make [Enter]
[root@bordeaux php_ext]# make install [Enter] (as root)

Step 6

Open make_modules.sh in your favorite editor and uncomment the line ‘make install’ and run make_modules.sh.

[root@bordeaux php_ext]# bash make_modules.sh [Enter] (as root)

Step 7

Go to ‘./tmp/modules/’ directory and copy ming.so to ‘/usr/lib/php/modules/’

1
2

[root@bordeaux php_ext]# cd tmp/modules/ [Enter]
[root@bordeaux modules]# cp ming.so /usr/lib/php/modules/ [Enter] (as root)

If ming.so is not found in ‘php_ext/tmp/modules/, then update your db using ‘updatedb’ and locate ming.so and if found on locate, then copy it to ‘/usr/lib/php/modules/’. If not found at all, try recompiling or issue some random commands related to make.

Step 8

Go to ‘/usr/local/lib/’ and check if libming.so, libming.so.0 etc. are present there. If yes proceed else I don’t know what to do

Step 9(a)

Go to ‘/usr/lib/php/modules/’ and issue these commands.

1
2
3
4

[root@bordeaux modules]# ln -s /usr/local/lib/libming.so libming.so (as root)
[root@bordeaux modules]# ln -s /usr/local/lib/libming.so.0 libming.so.0 (as root)
[root@bordeaux modules]# ln -s /usr/local/lib/libming.so.0.3.0 libming.so.0.3.0 (as root)
[root@bordeaux modules]# ln -s /usr/local/lib/libming.so.0.4.0 libming.so.0.4.0 (as root)

Step 9(b)

Go to ‘/usr/lib/’ and issue these commands.

1
2
3
4

[root@bordeaux lib]# ln -s /usr/local/lib/libming.so libming.so (as root)
[root@bordeaux lib]# ln -s /usr/local/lib/libming.so.0 libming.so.0 (as root)
[root@bordeaux lib]# ln -s /usr/local/lib/libming.so.0.3.0 libming.so.0.3.0 (as root)
[root@bordeaux lib]# ln -s /usr/local/lib/libming.so.0.4.0 libming.so.0.4.0 (as root)

Step 10

Restart the httpd service by issuing the command below

[root@bordeaux root]# service httpd restart [Enter] (as root)

Step 11

Write a file ‘/var/www/html/info.php’ with following contents

phpinfo();

and point your web browser to http://localhost/info.php . Now search for ‘ming’ and check whether its enabled or not.

If enabled, yes you have successfully installed php-ming Hope this helps.

Recently, I bought this domain name and shifted all my blogs here on saini.co.in . As I chose wordpress as the software to blog. So, just installed it and started using it right away. Installing wordpress is one of the most easiest things that you’ll ever do. Below is a step by step howto on installing wordpress and importing your current wordpress.com blog to your domain.

Step 1:

Download latest version of wordpress from here.

Step 2:

Go to the directory where you want to install it. Here I am taking gofedora.com as reference website where we want to install the wordpress and ~/htdocs/ as the web directory for gofedora.com . Modify above details in accordance with your needs.

If you downloaded .zip format then do this

[saini@bordeaux htdocs]# unzip wordpress-X.X.X.zip [Enter]

If you download .tar.gz format then do this

[saini@bordeaux htdocs]# tar -xvzf wordpress-X.X.X.zip [Enter]

Step 3:

[saini@bordeaux htdocs]# mv wordpress/* . [Enter]

If you visit http://gofedora.com now, you’ll get an error as shown in the image below …

Step 4:

Open the file wp-config-sample.php in your favorite text editor and edit the things shown in the image below.

Enter your database name, database username, database password and the table prefix for the wordpress database. e.g. one can use linux_ as table prefix. If you have the database on the same system, then there is no need to change the database host otherwise change it accordingly.

Step 5:

[saini@bordeaux htdocs]# mv wp-config-sample.php wp-config.php [Enter]

Step 6:

Go to http://gofedora.com/ and you’ll see a welcome page if you gave correct setting in wp-config.php . The page is like in the image below.

Fill the settings properly. Anyway you can change them afterwards. Fill the blog name and email id and click Install Wordpress.

Step 7:

You’ll see a web-page like in the image below, if everything goes fine. Copy the password on the page and paste at some temporary place and click login.

Step 8:

You’ll be presented with a login page. Enter ‘admin’ as username and the password you copied from the previous page.

Step 9:

Congratulations ! You have successfully installed wordpress and created the admin login. Go to Users -> Authors & Users and click Edit in the row with admin as author. Change the password on the next page as below ..

This is all you have to do to install wordpress. Below is how you import wordpress.com blog to your domain.

Step 1:

Login as admin on you wordpress.com blog and go to Manage -> Export and download the exported blog to your system as show in the image below.

Step 2:

Create directory named ‘uploads’ in ~/htdocs/wp-content/ and change permissions to 777 so that wordpress can upload your blog there.

1
2
3

[saini@bordeaux htdocs]# cd wp-content [Enter]
[saini@bordeaux wp-content]# mkdir uploads [Enter]
[saini@bordeaux wp-content]# chmod 777 uploads [Enter]

Step 3:

Go to Manager -> Import section and click on ‘wordpress’ . Upload the .xml file that you download from your wordpress.com blog in step 1 on the page as shown in the image below ..

Step 4:

If uploading goes successful, then all your posts will be imported from your wordpress.com blog and will be stored in the database as gofedora.com . Now it will ask you for the author of the new blog posts at gofedora.com as show below …

Step 5:

Change the permission of uploads back to normal as show below

[saini@bordeaux wp-content]# chmod 744 uploads [Enter]

Everything is done. Now you blog has been shifted to your domain and you can go on with the new blog. But keep in the mind the the images you used in wordpress.com blog posts are not stored in your local database, they are still linked back to your wordpress.com blog images. So, don’t just go and delete your wordpress.com blog. That would be fatal.

The steps for installing wordpress on a windows system are the same, but you have to use some notepads and whatever to edit files

Enjoy blogging at your domain. Hope the above howto helps.
