Hello world!

Welcome to lynxphp! I’m Callum Macrae, administrator of lynxphp and a PHP developer. I’ve been around for a while, but I’ve never actually contributed anything to the developer community, so I thought I would start this website to share my knowledge (and to help myself learn new stuff)! I will attempt to provide useful information and tutorials about PHP, in addition to other generic web topics like server management and third-party scripts. I probably won’t be writing any articles about front end development (HTML, CSS, Javascript, etc.) because I much prefer backend development. (Sorry!)

There is one thing I will never teach anyone, and that is how to say “Hello World!”. For a start, I’m going to assume you know the very basics of PHP, and I also only give real-life examples.

Over the next week or so, I will be attempting to publish an article daily. Okay, that’s not quite as impressive as it sounds – I have loads already saved to drafts that I did while I was buying the domain! When I’ve run out of saved articles, I will hopefully be writing about one weekly.

Until next time!

~Callum

UPDATE: Okay, I may have strayed from this a little bit; the site is no longer exclusively about PHP (I'm not even a PHP developer any more). It's not even called lynxphp any more. Updates on this soon…

foreach ($a as $chr) {
  echo chr($chr);
}

Basic "Hello World!" PHP script, for those of you disappointed by Callum's lack thereof.

You're doing it wrong!

lib/mysite/controllers/HelloController.php:

<?php
namespace mysite\controllers;

class HelloController
{
    public $a = array();

    public function __construct()
    {
        $this->a = array(0x48,0x65,0x6c,0x6c,0x6f,0x20,0x57,0x6f,0x72,0x6c,0x64,0x21);
    }

    public function sayHello()
    {
        $hello = null;
        foreach ($a as $chr)
        {
            $hello .= chr($chr);
        }
        require(VIEW_PATH . "/hello_world.php");
    }

}

index.php:

<?php
define("VIEW_PATH", __DIR__ . "/views");

require_once(__DIR__ . "/lib/mysite/controllers/HelloController.php");

use mysite\controllers\HelloController;

$site = new HelloController();
$site->sayHello();

views/hello_world.php:

<!DOCTYPE html>
<html>
        <head>
                <title>My Site: <?php echo $hello; ?></title>
        <head>
        <body>
                <h1><?php echo $hello; ?></h1>
        </body>
</html>
