Installing php driver for MongoDB

PHP      &   mongoDB

This is the post where I will configure php to work with mongoDB. On my previous post I have put the teps I followed to install mongoDB on my Ubuntu [TurnKey Linux] running on VirtualBox.
sudo pecl install mongo
2.Open your php.ini file and add to it:
It is recommended to add this to the section with the other "extensions", but it will work from anywhere within the php.ini file.
3.Restart your web server (Apache, nginx, etc.) for the change to take effect.
pecl requires that pear be installed. For those using apt-get, you may need to run the following:
sudo apt-get install php5-dev php5-cli php-pear
However, you can download the source for the driver and can compile it manually :
shell> tar -xzvf mongo-1.2.6.tar.gz
shell> cd mongo-1.2.6
shell> phpize
shell> ./configure
shell> make
shell> make install
Check with the phpinfo

Starting MongoDB and php on Ubuntu

Installing MongoDB on Ubuntu:
1. Add 10gen package to source.list 
The 10gen package contains the latest mongoDB version, append below line to the end of the file “/etc/apt/sources.list
deb dist 10gen
For example, you can vim the “source.list” and append the 10gen package like this :
$ sudo vim /etc/apt/sources.list
File : /etc/apt/sources.list
#...content omitted ...
## This software is not part of Ubuntu, but is offered by third-party
## developers who want to ship their latest software.
deb natty main
deb-src natty main
 #mongo repo ##########
deb dist 10gen

 2. Update package
Update the modified “/etc/apt/sources.list” :
sudo apt-get update
Now, a new “mongodb-10gen – An object/document-oriented database” is available for install.
  3. Add GPG Key
10gen package required GPG key, import it :
sudo apt-key adv --keyserver --recv 7F0CEB10
   4. Install mongodb-10gen
Everything is ready, now you can Install the mongoDB package :
sudo apt-get install mongodb-10gen
    5. Post-InstallationVerification
Now, mongoDB is installed, started, and auto start mongoDB script is generated to “/etc/init/mongo” and “/etc/init.d/mongo“. In addition, all mongoDB files are copied to “/usr/bin” folder.

The main configuration file “mongodb.conf” is located at “/etc/mongodb.conf“, change the values to customize your mongoDB server.

File : mongodb.conf
# mongodb.conf
# Where to store the data.
# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
#where to log
logpath=/var/log/mongodb/mongodb.log logappend=true
#port = 27017
   6. Verification
To verify it, just connect it with “mongo”
$ mongo
MongoDB shell version: 1.8.1 connecting to: test
on my next post I will try to connect php with this mongoDB.

Parsing Email with PHP

I was working for a Email Advertisement tool,recently. And the first thing I was put to work with is to develop a parser that parses and incoming email and decides whether it is a bounced back email. After couple of googling I got some fare enough solution that I wanted to use for the solution. The steps I followed for the solution are adopted from the following :
HOWTO: Email Bounce handling with PHP, Exim & CPanel, Catch bounces from non-deliverable emails

And the very basic parser I wrote can be downloaded from the following location:
Download the email parser for bounce management
[Bascially It's a codeIgniter controller, but you can use it as you wanna use it]

However, I had to go some more details parsing, later to decide the type of bounce or the reason for the bounce.First I tried parsing the log file for the exim [exim_mainlog file] and then parsing the entire body of the bounced back emails. I will share two more posts on them in this series.
