Arrays in php

An array stores multiple values in one single variable:

<?php
$cars=array("Volvo","BMW","Toyota");
echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . ".";
?>

Array in PHP

In PHP, the array() function is used to create an array:

array();

In PHP, there are three types of arrays:

• Indexed arrays - Arrays with numeric index
• Associative arrays - Arrays with named keys
• Multidimensional arrays - Arrays containing one or more arrays

Internet Attack March 2013

Huge cyber-attack causes worldwide disruption

A record-breaking cyber-attack targeting an anti-spam watchdog group has sent ripples of disruption coursing across the internet, experts have said.

Spamhaus, a site responsible for keeping ads for counterfeit Viagra and bogus weight-loss pills out of the world's inboxes, said it had been buffeted by the monster denial-of-service attack since mid-March, apparently from groups angry at being blacklisted by the Swiss-British group.

"It is a small miracle that we're still online," Spamhaus researcher Vincent Hanna said on Wednesday.

Denial-of-service attacks overwhelm a server with traffic, like hundreds of letters being jammed through a mail slot at the same time.

Security experts measure those attacks in bits of data per second. Recent cyberattacks, like the ones that caused persistent outages at US banking sites late last year, have tended to peak at 100 billion bits per second.

But the furious assault on Spamhaus has shattered the charts, clocking in at 300 billion bits per second, according to San Francisco-based CloudFlare Inc, which Spamhaus has enlisted to help it weather the attack.

"It was likely quite a bit more, but at some point measurement systems can't keep up," CloudFlare chief executive Matthew Prince wrote in an email.

Patrick Gilmore of Akamai Technologies said that was not an understatement.

"This attack is the largest that has been publicly disclosed, ever, in the history of the Internet,'' he said.

Disgruntled service providers

It is unclear who exactly was behind the attack, although a man who identified himself as Sven Olaf Kamphuis said he was in touch with the attackers and described them as mainly consisting of disgruntled Russian internet service providers who had found themselves on Spamhaus' blacklists.

There was no immediate way to verify his claim.

He accused the watchdog of arbitrarily blocking content that it did not like.

Spamhaus has widely used and constantly updated blacklists of sites that send spam.

"They abuse their position not to stop spam but to exercise censorship without a court order," Kamphuis said.

Gilmore and Prince said the attack's perpetrators had taken advantage of weaknesses in the Internet's infrastructure to trick thousands of servers into routing a torrent of junk traffic to Spamhaus every second.

Both experts said the attack's sheer size had sent ripples of disruptions across the internet as servers moved mountains of junk traffic back and forth across the web.

"At a minimum there would have been slowness," Prince said, adding in a blog post that "if the Internet felt a bit more sluggish for you over the last few days in Europe, this may be part of the reason why."

At the London Internet Exchange, where service providers exchange traffic across the globe, spokesman Malcolm Hutty said his organisation had seen "a minor degree of congestion in a small portion of the network."

But he said it was unlikely that any ordinary users had been affected by the attack.

Object Oriented JavaScript Frameworks

Some Object Oriented JavaScript Frameworks which help you to build are rock your website

• Mootools
• Prototype js
• Dojo
• jquerymobile

Some Basic Linux Commands

cat – Shows the contents of files to the screen.

Usage:

1 2	# cat file.txt # Hello World

Also this command can be used to count the number of lines, words and characters in a file:

1	cat  | wc -l

- number of lines

1	cat  | wc -w

- number of words

1	cat  | wc -c

- number of characters
To search for a word in a file you can use:

1	# cat  | grep <some word>

cd – Change directory
the ‘cd’ command should be used followed by the name of a directory including the full path to that directory. If you execute ‘cd’ without arguments the working directory will be switched to your ‘home directory’.
Usage:

1	# cd /path/to/directory_name/

To move one directory up, you can use the shortcut command:

1

# cd ..

cp – Copy files and directories
Usage:

1	# cp <SOURCE> <DESTINATION>

Example:

1	# cp /root/file /tmp/

With this command you will make a copy of ‘file’ located in the ‘/root’ directory to the ‘/tmp’ directory if it does not exist. It will overwrite it in case the ‘file’ already exists.

df – Check the amount of free disk space on the filesystems.
Usage:

1

# df

To get a more easily readable (human-readable) output of the command use:

1

# df -h

free – Gives information about used and free memory and swap space on a Linux machine.
Usage:

1

# free

The -b option shows the amount of memory in bytes; the -k option (set by default) shows it in kilobytes; the -m options shows it in megabytes.

rm – Removes directories, files, symbolic links, etc. from the filesystem.
Usage:

1	# rm <OPTION> <FILE>

Most common options for this command are:
-f : ignore nonexistent files, never prompt
-r : remove directories and their contents recursively
-v : explain what is being removed
Note: Always double check before removing any file or directory.

ls – Displays a list of files and directories in a specific directory.
If you enter just ‘ls’ without specifying a directory, it will display a list of files and directories in the working directory.
Usage:

1

# ls

Most common options for this command are:
-a : shows all files and folders including the hidden ones.
-l : use a long listing format

mv – Moves files and directories from one directory to another or renames a file or directory.
Usage:
Move ‘file’ from ‘/root’ to ‘/tmp’ directory

1	# mv /root/file /tmp/

Rename ‘file1′ to ‘file2′

1	# mv file1 file2

passwd – change user password
Usage:

1	# passwd <USERNAME>

If you execute just ‘passwd’ without specifying the username, you will change your root password.
Note: Never use passwords that are easily guessable, such as passwords based upon names, street addresses, dictionary words, significant dates, etc… A strong password consists of a combination of letters (both upper and lower case), numbers and special characters and it should be at least 8 characters long.

mkdir – Creates directory(ies) if they don’t already exist
Usage:

1	# mkdir <NEW_DIRECTORY>

Example:

1	# mkdir /var/www/<NEW_DIRECTORY>
