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");

    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
