Skinning a cat (Or how many ways to output "Hello World!")

[hansford]

You guys are really bored, but ah well. Here is my addition.

print_r("hello world");

exec(print "hello world");

foreach(array('h','e','l','l','o',' ', 'w','o','r','l','d') as $letter)
{
	echo $letter;
}

function x($a, $b)

{

    $res = 0;

    while ($b) {

        if ($b%2) $res += $a;

        $a <<= 1; 

        $b >>= 1;

    } 

    return $res;

}


function y($j,$k) 

{

    echo chr($j+58|($k?0x20:0));

}



$a = str_split(x(0xC0421DB,0x07),2) ;

$b = str_split(x(0x5CDD207, 0x1E),2);


array_walk($a , 'y');

echo ', ';

array_walk($b , 'y');

You'll have to run this one in your browser.

<?php

$expected = 'Hello, World!';
$string = '';
$charPool = range(32, 126);
unset($charPool[2], $charPool[7]);
$charPool = implode('', array_map(function($char){ return chr($char); }, $charPool));

echo <<<HEREDOC
<style type="text/css">#hello-world span{font-family:monospace;width:20px;height:20px;display:inline-block;text-align:center;vertical-align:middle;</style><div id="hello-world"></div><script type="text/javascript">for(var el=document.getElementById("hello-world"),expected="Hello, World!",pool='{$charPool}',i=0;i<expected.length;i++){var newEl=document.createElement("span");el.appendChild(newEl),el.children[i].interval=setInterval(function(e){var l=Math.floor(Math.random()*(pool.length+1));el.children[e].textContent=pool[l],el.children[e].textContent==expected[e]&&clearInterval(el.children[e].interval)},50,i)}</script>
HEREDOC;

?>

Nobody said we can't use Javascript, right? Edited October 13, 2015 by scootstah
