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 is the output of the following script ?

  <?php
  function generate() {
      for ($i = 1; $i <= 3; $i++) 
          yield $i;
  }
  $generator = generate();
  if(is_array($generator))
    echo "Is Array";
  elseif(is_object($generator))
    echo "Is Object";
  else

Is Object

Is none of the above

3.Assuming that the code below is in a file named "test.php" and that PHP has full rights over the file, what happens if the file is executed from the command line without any arguments ?

The script exits without doing anything

The file test.php is deleted

A notice is thrown because $argv[0] is not defined and the script fails.

4.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

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

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

    $human->name = 0;
    $dog->name = "";

($human == $dog)

($human === $dog)

($human->name == $dog->name)

7.Which of th following statements about object serialization are true ?

After serializing an object, a programmer can fully recreate that object in another file by calling unserialize() even if the class definition doesn't exist.

Static class properties can be serialized, but can not be unserialized.

Static class properties can not be serialized.
