KRDS technical testThese exercises are limited in time. Only write the necessary lines of code to solve the problems. Indications of the number of expected single line of code (SLOC) and time are given for each exercise. DO NOT REINVENT THE WHEEL. These are offline test. Only the PHP doc and MySQL document in offline format are given. We are waiting for the most clever and efficient way to solve the exercise. Maximum allowed time is 2 hours

1. JSON & XML1.1. JSON (~ 3 minutes, ~ 5 SLOC) Input: An object describing a person. The object has the following properties : First name Last name Address (door number, street and city) A list (array) of phone number (mobile, landline and skype number). Output: Guidelines: Please write the textual representation of the JSON object above.

Write a plain text response, no PHP is asked here!1.2. XML (~ 5 minutes, ~ 15 SLOC) Input: Output: Guidelines: Please write the exact XML representation of the JSON object you write. Your previous JSON object

Write a plain text response, no PHP is asked here!

1.3. PHP (~ 15 minutes, 4 < SLOC < 20) Input: Output: Please write the PHP code to echo the Skype phone number o Of your JSON-described object o Of your XML-described object Please write the JAVASCRIPT code to access the Skype hone number of your JSON object Your previous JSON object and XML representation of this object

Guidelines:

No Ajax code waited at all!

2. Web services (read, ~ 15 minutes, ~ 10 SLOC)2.1. JSON Input: The following URL output details for employee #18 using JSON format: http://demo.tools.krds.com/dispatch_ws.php?action=get&id=18&format=json Output: Output to the browser the name property of the employee #18 This URL is slow to respond (~15 sec), its normal and must be handle accordingly in your code

Guidelines Use CURL only Use correct timeouts and correct encoding

2.2. XML (~ 7 minutes, ~10 SLOC) Input: The following URL output details for employee #18 using XML format: http://demo.tools.krds.com/dispatch_ws.php?action=get&id=18&format=xml Output: Output to the screen the name property of the employee Output to the screen the type attribute of the employee This URL is slow to respond (~15 sec), its normal and must be handle accordingly in your code

Guidelines: Use CURL only Use SimpleXML Use correct timeouts and correct encoding

3. Web services (Write)3.1. Create a new employee record (~ 15 minutes, ~ 15 SLOC) Input: The following URL creates a new employee http://demo.tools.krds.com/dispatch_ws.php?action=create Expected POST data to create a new employee is name and type Web service returns HTTP 201 CREATED response code if employee creation is successful

Output: Create a new employee and output OK to the browser if and only if creation is successful

Guidelines Use PHP & CURL only

4. Regular expressions4.1. Data extracting (~ 5 minutes, ~ 5 SLOC) Input: An example text:

On February 13, 2009, at exactly 23:31:30 (UTC) the decimal representation of Unix time was equal to 1234567890. Parties and other celebrations were held around the world, among various technical subcultures, to celebrate this day.

Output: Output to the browser all numbers greater than 4 digits contained in the given input text using PHP.

Guidelines Use regular expressions Of course, the output must work whatever is the text given as input

4.2. Data replacing (~ 4 minutes, ~ 2 SLOC) Input: The following text: During the day, Damien is working. Output: From the given input, output the following text to the browser: Damien is happy to work. Guidelines Use regular expressions functions only No more than 2 lines of code expected. Bigger code will be rejected

5. Common problems5.1. Bad output in PHP (~ 7 minutes) Input: The 4.1.php file that can be found along with this document Currently, this file renders like this:

Output: Fix the file to get the correct output in the browser (Hello Lorane !) and Explain how you proceeded DO NOT remove or alter existing lines in the given file

5.2. Bad output in HTML (~ 3 minutes) Input: The 4.2.html file Currently, this file renders like this:

Output: Describe 2 solutions to fix the problem and get the correct output in the browser: Hola cmo est? DO NOT remove or alter existing lines in the given file

5.3. Security issue (~ 15 minutes)

Input: Go to http://wargame2k10.nuitduhack.com:8086/

Output: Hack this login form. Hacking is successful when the following screen will be displayed:

Please provide the full code that will appear once cracking is successful (end of the code is masked in black in the image above this is the code you must get)
