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

5.When dealing with cloned objects in PHP, which of the following statements are true ?

The programmer can make use of the __clone() magic method to stop an object from being cloned.

As of PHP 7.0.0, members of cloned objects can be accessed in a single expression without any assignments... Like this:
(clone new DateTime())->format('Y');

The __clone() magic method of a class is called before the actual cloning of the object occurs allowing the programmer to alter values before the cloning process begins.

                        $c = 0xFF;
                        $d = $b + $c;
                        $e = $d * $b;
                        $f = ($d + $e) % $a;
                        print ($f + $e);
