A lot of users who are looking for web hosting usually take the location into matter to add to the complicated equation when looking for a web hosting company however it is not always the most important factor. It’s not completely unimportant but it is important to some point, you would at least want to have the datacenter at least in the same continent.
Of course, you won’t get the best speeds off your web hosting company if you are located in North America, it wouldn’t be the smartest idea to get your web hosting somewhere in southern Asia as it will be very slow & will be crawling for you and most of your clients if they are located in North America.
However, if you do take web hosting in a place such as Montreal, QC which is 5 hours north of New York, NY – The speed will not be that much different if it was actually located in Montreal, QC or New York, NY because the difference between the two is close to nothing at the speeds that the internet runs at.
To conclude, the best idea is to get your web hosting services at a company close to you but not necessarily very close but not necessarily very far that your web site would be very slow.

A lot of people are getting hiring people to install FFMPEG as they think it’s a difficult task, but it’s much easier than you think if you follow these instructions. You should have root access & basic Linux knowledge to the server to follow these instructions.

1. Create a directory to do our work in
mkdir ~/ffmpeg
cd ~/ffmpeg
2. Get all the source files
wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/ essential-20061022.tar.bz2
wget http://rubyforge.org/frs/download.php/9225/ flvtool2_1.0.5_rc6.tgz
wget http://easynews.dl.sourceforge.net/sourceforge/ lame/lame-3.97.tar.gz

bunzip2 ffmpeg-php-0.5.0.tbz2; tar xvf ffmpeg-php-0.5.0.tar
tar zxvf libogg-1.1.3.tar.gz
tar zxvf libvorbis-1.1.2.tar.gz
4. Create the codecs directory & import them
mkdir /usr/local/lib/codecs/
mv essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/
5. Install SVN/Ruby (Depends on OS, this is for RHEL/CentOS)
yum install subversion
yum install ruby
yum install ncurses-devel
6. Get the latest FFMPEG/MPlayer from the subversion
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
7. Compile LAME
cd ~/ffmpeg/lame-3.97
./configure
make
make install
8. Compile libOGG
cd ~/ffmpeg/libogg-1.1.3
./configure
make
make install
9. Compile libVorbis
cd ~/ffmpeg/libvorbis-1.1.2
./configure
make
make install
10. Compile flvtool2
cd ~/ffmpeg/flvtool2_1.0.5_rc6
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install
11. Compile MPlayer
cd ~/ffmpeg/mplayer
./configure
make
make install
12. Compile FFMPEG
cd ~/ffmpeg/ffmpeg
./configure --enable-libmp3lame --enable-libogg --enable-libvorbis --disable-mmx --enable-shared
echo '#define HAVE_LRINTF 1' >> config.h
make
make install
13. Finalize the codec setups
ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51
14. Compile FFMPEG-PHP
cd ~/ffmpeg/ ffmpeg-php-0.5.0
phpize
./configure
make
make install
15. Install FFMPEG-PHP (make sure the php.ini path is correct.)
echo 'extension=/usr/local/lib/php/extensions/ no-debug-non-zts-20020429/ffmpeg.so' >> /usr/local/Zend/etc/php.ini
16. Restart Apache to load FFMPEG-PHP (Depends on OS, this is for RHEL/CentOS)
service httpd restart
17. Verify if it works
php -r 'phpinfo();' | grep ffmpeg
If you get a few lines such as
ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0
Then everything is installed and working. FFMPEG, FFMPEG-PHP, MPlayer, MEncoder, flv2tool, LAME MP3 encoder & libOGG.
Top 5 new (and cool!) features in PHP5 that you probably haven’t heard of
Posted: January 3, 2007 at 11:23 pm |
(27) Comments
PHP5 has brought so much new features but because of its big syntax changes, a big percentage of the PHP developing base has not made the change. Here are the top 10 new features that could change your mind.
5: Better error handling with exceptions
I’m sure every PHP developer had been staring at the famous white screen with a “Syntax error” clueless at where the error is really at. With PHP5, you can actually handle PHP errors and do whatever you want with them, but that’s not all. They have also included exceptions which I’m sure most C++ or Java developers use. The good part is that instead of simply failing on with close no errors to you, you could put a few checks before and information you could need such as maybe a print_r() on an array. I have written an article about this: http://vexxhost.com/blog/?p=21
4: Completely rewritten MySQL extension
The MySQL databases are the PHP’s partner in crime. Many developers use this database system in their website’s because it is on of the easiest, free, open-source database software. However, its performance combined with PHP4 was close to poor. Introduced with PHP5 is a newer, rewritten, optimized MySQL extension which was also compatible with MySQL 5.0. It has also introduced other functions such as: Prepared statements, SSL connections, Multi-query functions.
3: A heck of a lot more useful functions
I have a few favorite PHP5 functions which speed up time while coding & enhances the website’s performance. One of my favorites is the __autoload() function – What it does that it would be called if a class that was created and did not exist. It provides you with the class name. This is useful because you don’t need to manage what includes you need for X and Y file and reduces the load for those who simply include all the classes in for every single PHP file. Also, another favorite is file_put_contents() which reduces the 6 lines of code to add something to one.
2: Finally! SQLite database support!
I’m sure a lot of developers will be happy about this one. While MySQL is very popular among most PHP developers, SQLite is much different than it. It actually uses normal files and reads them. It does not need a daemon (or called server) to run in order to execute any queries on it. It makes a better smaller database for these low traffic sites.
1: The best damn OOP support period
PHP programmers have spent an awful of long time trying to create hacks so in order that PHP can make a better OO programming language. Finally, they are rewarded with OO support that either PHP3 or PHP4 can match. It has anything you usually see in most of the other established coding languages. From Constructors, Destructors, Public, protected, private properties & methods, Interfaces, Abstract classes, Class type hints, Static properties and methods, Final properties and methods & a whole suite of magical methods.
That’s the top 5 for me. I hope you think that PHP5 deserves a try! (and we offer it with our hosting plans!)
What FFMPEG-PHP can do and how to use the most out of it
Posted: December 20, 2006 at 8:49 pm |

You’ve probably heard of ffmpeg-php and it’s wide usability mostly in sites that involve with videos such as YouTube or any other similar site. Here’s a bit of an introduction to it and how to use it.
First thing, you’ve got to check that your web hosting provider actually has ffmpeg & ffmpeg-php extension installed on your account and then you could get started with ffmpeg. You can check if it’s installed by creating a PHP script and executing the following code:
extension_loaded('ffmpeg') or die("ffmpeg extension not loaded");
If you get “ffmpeg extension not loaded” then your web hosting provider does not have ffmpeg installed, if you get nothing, then you’re one the good track!
ffmpeg-php is very simple to learn, what it is pretty much is an interface that works with the ffmpeg software to make it easier for PHP developers to access.
Like any object in PHP, you’ll have to start with creating a new instance of it. You can do that by using the following line:
$ffmpegInstance = new ffmpeg_movie(“/path/to/movie/”);
Now that you’ve had that, you can use that instance to use the many features of ffmpeg-php which are from knowing the duration of the movie/audio in seconds to retrieving the bitrate of the movie/audio file.
Once here, it’s pretty much like object oriented programming, ex:
$ffmpegInstance->getDuration(); // Gets the duration in secs.
$ffmpegInstance->getVideoCodec(); // What type of compression/codec used
This can be very helpful when coding anything that has to do with uploading videos because you can know a lot of information about it. I’ve made a small script that pretty much retrieves all the information that ffmpeg can get right here
Creating PDF’s on the fly using PHP & FPDF
Posted: December 3, 2006 at 12:27 pm |

Generating PDF’s is an easy method to make a very nice printable and/or savable version of an article. This could be helpful in a WordPress blog or any articles website. This method utilizes the popular FPDF class.
First of all, I suggest you get the latest FPDF version from here. I suggest creating a directory such as “pdf” on your web hosting space. You will need to place the fpdf.php into that directory, you will only need it.
Let’s make our first “Hello World” example. Place the following in a file called test.php:
<?php
require('fpdf.php');
$pdf=new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Now let’s see that code line by line…
require('fpdf.php');
This line includes our FPDF class that we need to create the PDF file.
$pdf=new FPDF();
This line creates a new instance of the FPDF class which will be binded to $pdf
$pdf->AddPage();
This line tells FPDF to add a new page to the PDF file; obviously we need one page so we will call this function once.
$pdf->SetFont('Arial','B',16);
This line tells the FPDF class to change the font to Arial, bold, 16 pt.
$pdf->Cell(40,10,'Hello World!');
This line is just like the “echo” of PHP, the text fields in PDF files are just sort of rectangles with text in them, so we want the width of 40 pt. and a height of 10 pt., the third value is the text to be written in that rectangular box.
$pdf->Output();
Our final line, which pretty much means: “we’re done, show us our PDF!”
That’s a very simple FPDF usage, however, here is a bit of more advanced version of FPDF usage:
<?php
require('fpdf.php');
$pdf=new FPDF("L", "mm", "A4");
$pdf->AddPage();
$pdf->SetFont('Arial','BIU',30);
$pdf->SetTextColor(0,0,255);
$pdf->Cell(60,20,'PDF+PHP Test',1,1,C,0);
$pdf->Output();
?>
Now let’s do a quick review of that more advanced code:
$pdf=new FPDF("L", "mm", "A4");
This will create a new instance but instead will default to creating landscape pages because of the first L, P can be used instead to default to portrait pages. The second value is the default measurement unit, a choice of point (pt), millimeter (mm), centimeter (cm) and inch (in) is given. The last value is the size of the page, the choice of A3, A4, A5, Letter & Legal is given.
$pdf->AddPage();
Simple function, just add the page, you can tell the function to create either a portrait (P) or landscape (L) by giving it as a first value (ex: $pdf->AddPage("L"), $pdf->AddPage("P")).
$pdf->SetFont('Arial','BIU',38);
This required function again says that we want an Arial, 30 mm in size (because of the default size unit), the 'BIU' simply tells that we want it to be Bold, Italic & Underlined.
$pdf->SetTextColor(0,0,255);
This sets the default text color for the text we will be writing, I’ve chosen blue here, the first value is red (r), the second is green (g) & blue (b).
$pdf->Cell(60,20,'PDF+PHP Test',0,1,C,0);
This makes the so famous rectangle with 60 mm of width & 20 mm of height, we wrote ‘PDF+PHP Test’ and the first 0 means we do not want a border. The 1 next to it means that once it’s done the cell, it will go to the beginning of the next line, if 0 is provided, then it will be to the right of it, if 2 is provided then it will go below. The C is just the alignment which is center of the text inside the box, possible values are left (L), center (C), right (R).
$pdf->Output();
Output our brand new colorful PDF file!
Thanks for reading!
