1.Considering the code below, which of these statements are true?

<?php 
    ini_set("allow_url_fopen", "1");
    $page = file_get_contents("http://www.codepunker.com");
    if($page!=FALSE)
    echo "Successfully fetched website contents";
    else
    echo "An error has occurred";

The correct setting for loading web pages from a script is "allow_url_include"

The "allow_url_fopen" option can not be changed through ini_set. It can only be set in php.ini for security reasons

The if statement should be "if($page!==FALSE)" because "file_get_contents" can return non boolean values which evaluate to false

2.What output will this code produce ?

<?php 
    class Disney
    {
        public $cartoon;

        function __construct($cartoon)
        {
            $this->cartoon = $cartoon;
        }
    }

    $disney = new Disney("The Beauty and The Beast");
    $waltDisney = $disney;
    $waltDisney->cartoon = "Pinocchio";
    echo $disney->cartoon;

"Pinocchio" because $waltDisney and $Disney are pointing to the same object

"The Beauty and The Beast" because the $cartoon property in the $waltDisney object was changed

NULL because the Disney class was not instanciated inside the $waltDisney variable

3.What happens when you run the following MySQL Query ?

  
  CREATE TABLE PRIMARY (ID int);
  

Syntax Error - PRIMARY is reserved in MySQL and should be quoted to be used as a table name

Syntax Error - PRIMARY is reserved in MySQL and can not be used as a table name

A table called PRIMARY containing a column called ID is created

4.When working with unfamiliar code, what is the best way to find out in which file a class is defined ?

Using ReflectionClass:

  <?php
  $reflection = new ReflectionClass('ClassName');
  echo $reflection->getFileName();
  ?>

Using the grep command to search through the application files:

  <?php
  $out = array();
  exec("grep -r 'Classname' .", $out);
  var_dump($out);
  ?>

Using the get_declared_classes() function:

  $classes = get_declared_classes();
  var_dump($classes);

5.What is the output of the code below ?

<?php 
  $a = array();
  $a[0] = 1;
  unset($a[0]);
  echo ($a != null) ? 'True' : 'False';

True

False

Parse Error

6.What is the output of the code below ?

  
    <?php
    namespace animals;

    ini_set('error_reporting', E_ALL);
    ini_set('display_errors', 'on');

    class Cat
    {
      static function Definition()
      {
        return 'Cats are ' . __NAMESPACE__;
      }
    }

    namespace animals\pets;

    class Cat
    {
      static function Definition()
      {
        return 'Cats are ' . __NAMESPACE__;
      }
    }

    echo Cat::Definition();    
  

Cats are animals\pets

Fatal error: Cannot redeclare class Cat

Fatal error: Cannot re-declare class animals\pets\Cat in sub-namespace

7.Which of the statements about traits below are true ?

PHP is "single inheritance" so traits allow coders to reuse sets of methods from the trait freely in several independent classes

An inherited member from a base class is overridden by a member inserted by a Trait, but members from the current class override Trait methods.

If two Traits insert a method with the same name in a class that uses them, a fatal error is produced and this naming conflict can not be bypassed

8.When running PHP's built in FastCGI Process Manager (FPM) which of the following statements are true ?

Settings initialized in the php-fpm.conf file with php_admin_flag can not be overwritten in the code through ini_set()

It doesn't provide any easy way of debugging slow performing requests/scripts

The special fastcgi_finish_request() function allows PHP to finish request and flush all data while continuing to do various tasks in the background.

12.What is the result of the following code snippet? $array = array('a' => 'John', 'b' => 'Coggeshall', 'c' => array('d' => 'John', 'e' => 'Smith')); function something($array) { extract($array); return $c['e']; } print something($array);

13.Given the following array: $array = array(1,1,2,3,4,4,5,6,6,6,6,3,2,2,2); The fastest way to determine the total number a particular value appears in the array is to use which function?

array_total_values

duplicate() must accept its parameter by reference

You must use the clone operator to make a copy of an object

duplicate() must return a reference
