Current website development relies more on open source to handle forms and back end things. Whether it is a e commerce website or a portal, certain level of technical handling is there from server side. Certain redirection, conditional surfing based on ip address of client, privilege approving and database integration all are done by a software bundle named LAMP. LAMP is a short notation of individual software such as Linux (OS), Apache HTTP server, MySQL (DBMS) and of course PHP.

PHP has become one of widely used open source software product for developing hundreds of sites ranging from simple to complex one like WordPress. The P of LAMP may be sometimes replaced by another scripting language such as Perl or Python.

They four individual has got together to give the best performing web applications to PHP developers. Here are the benefits of MySQL and PHP explained further to get the idea why theyve been together to deliver efficient web applications.

Benefits of MySQL:

Very low licensing cost
Low hardware consumption
Execute anything from data houses holding terabytes of data
Ultra-fast loading
Table and Index partitioning
Master/Slave replication with high speed reconfiguration utility
Multi-version Transaction support
Highly robust
Efficient query engine
Secure encryption decryption functions
Open source freedom

Benefits of PHP:

Easy to use
Simplified task handling in heavy traffic sites
Open source
Secure
Low cost
Being open source new functionality have been added consistently
Simple coding style
Highly functional to code simple to shopping cart projects

As LAMP meant to be run on Linux platform, this software bundle is more reliable and performance giving. When you are on Linux platform, you are sure for one thing that is less down time. Benefits of Linux platform add more things to the Benefits of PHP and MySQL.

Hence, we can conclude that a reliable platform (Linux), an easy to manage and highly functional server side scripting language (PHP) and a flexible & low cost DBMS can give the PHP developers the edge of development which helps them in complex website development.

The Linux hard drive is partitioned in various partitions/volumes for effective management of your valuable data. Linux hard drive volumes start from the boot block where boot information of the operating system is stored. Last two byes of the Linux boot block contains boot block signature. In some cases, operating system cannot locate boot block signature and the disk cannot be accessed. It makes your significant data inaccessible and leads to data loss. Such cases require you to either restore data from backup or use Linux data recovery software to scan the drive and extract data from it.

For example, you might encounter an error message similar to the following one when you attempt to boot a Linux operating system based computer-

“Master boot record on /dev/hda has been updated.” Subsequent to the above error, you may also encounter further error message that states- “No boot signature found on partition”

The system cannot be booted in such cases and you face severe data loss situations. To recover your business-critical data in such cases, you are required to opt for Linux recovery tools.

Grounds of the issue

This problem most frequently occurs if you overwrite the LILO (Linux Loader) boot loader with the MBR (Master Boot Record) that was primarily installed on the /dev/hda disk volume. The boot loader might be overwritten if you try to install it using -M switch. Boot block corruption also results into the same problem. How to fix boot block corruption problem? In order to work around this problem, you have to overwrite the Master Boot Record with Linux Loader. It is possible with the help of /sbin/lilo Linux command. This command enables the operating system to overwrite MBR information on the /dev/hdX disk. Alternatively you can use LILO on the /dev/hda2 disk as:

boot=/dev/hda2 lilo -b /dev/hda2 lilo -M /dev/hda lilo -A /dev/hda 2

In case the above method does not work, you will have to reinstall operating system. As reinstalling the operating system removes all the data from Linux partition, you will need data recovery Linux methods to get your precious data back. Linux Data Recovery software employs highly-advanced Ext2 recovery algorithms to ensure absolute recovery. The advanced Ext3 recovery software are absolutely safe to use with read-only Linux recovery conduct.
