Lucky for you two! (Kayenta and Keito) You don't need to have master coding skills in Java for PhP, but that's not to say a basic understanding of it wouldn't help.
Example of PhP:
<!DOCTYPE html>
<html>
<head>
<link type='text/css' rel='stylesheet' href='style.css'/>
<title>PHP!</title>
</head>
<body>
<img src="Paste link in here"/>
<div class="header"><h1>
<?php
$welcome = "Let's get started with PHP!";
echo $welcome;
?>
Where the difficulty for most (I believe or most just for me) is with the if, else if, etc statements. Which Java uses a lot.
<?php
for ($dog = 1; $dog <= 10; $dog++) {
if ($number <= 9) {
echo $dog . ", ";
} else {
echo $dog . "!";
}
}; ?>
However before you do any of that you need to learn HTML and CSS. These two languages are the basics and VERY easy to learn. A child could learn HTML.
Repetition is KEY. Now while I say these things and flash a few lines of code you may be like 'Well shit Ben looks like you know your shit" and that's not true. I can pull a couple hundred out of my bank account, but that doesn't make me rich. Same for here.
Here's a good site to learn stuff on:
https://www.codecademy.com/Take about 24 hours to learn CSS and PhP over the course of a week or two and you'll have a much better understanding of how SL runs. Shit, I have a LoTGD test site up. PM on SL and I'll give you a link and give you admin powers and show you files and shit. (Note: mention of another LoTGD is not advertising as it's a test site to learn PhP. Nothing more. >.>)
If you don't want to learn code then look for Naruto pictures or make new enemies for the forest or write out new events or come up with a new shop idea and so on.
All in all though if you learn some code it will help immensely.
