Ruby のようなメソッドを PHP でも再実装

ruby_like.php

<?php
/**
 * ex.
 *   include 'ruby_like.php';
 */
function puts($args)
{
    print $args;
}

function p() 
{
    foreach(func_get_args() as $argments) {
        var_export($argments);
    }   
}

function pp()
{
    foreach(func_get_args() as $argments) {
        var_dump($argments);
    }   
}

function h($string, $quote_style = null, $charset = null)
{
    return htmlspecialchars($string, $quote_style, $charset);
}
