Get Off My Lawn

PHP Template Engine

I have been working on a php driven template engine. This is fairly light weight, and fast from all of my testing, but I was hoping to get some feed back on it. First I would like to show you an example usages before I show the actual library. For full documentation and more examples: http://plater.phpsnips.com/

This first part is a example users homepage

templates/user.tpl

<!DOCTYPE html>
<html>
    <head>
        <title>User Home Page</title>
    </head>
    <body>
        <h2>Welcome, $session.first.ucfirst();</h2>
        <p>
            Here is where you will find the last 5 images that you have uploaded.
        </p>
        $each("myimages"):
            <div style="border: solid 1px activeborder;margin-bottom: 5px;">
                <p>
                    <img src="images/$image;" />
                </p>
                <p>
                    $description;
                </p>
            </div>
        $endeach;
    </body>
</html>

This next section is the php part for the above template.

user.php

<?php
session_start();
require_once "Plater.php";
require_once "db.php";
$tpl = new Plater();

// Query a database
$user_id = (int)$_SESSION["user_id"];
$sql = mysql_query("select * from images where user_id = $user_id order by date desc limit 5");
$images = [];
// put into the array
while($row = mysql_fetch_assoc($sql)){
    $images[] = ["image" => $row["filename"], "description" => $row["descr"]];
}

// replacemet
$tpl->assign("myimages", $images);

// show
$tpl->show("templates/user.tpl");

That was just a little taste of the template system. Here are some of the current features that it has so far:

Import templates within the template
Run PHP functions
Run Custom functions
Tidy
Import css (decreases http requests)
Loops
globals
- $get
- $post
- $session
- $cookie
- $server
Template comments (Won't display in html output)
- Multi line: /$ Multiline comment $/
- Single line: $$ Single line comment
Remove empty tags after all replacements are done

And finally, here is the main library:
