This is a dead-simple method of flexible templating for PHP-based websites.
Setup
.template.html
<html>
<head>
<title><!-- %TITLE --></title>
<link rel="icon" href="/favicon.ico" type="image/x-icon" />
<style>
BODY { text-align: center; font-size: 110%; }
</style>
</head>
<body>
<!-- %BODY -->
</body>
</html>
.template.php

/** Stupid-simple Templating in PHP

function _ProcessTemplate() {
global $Template;
global $TemplateFields;
$TemplateFields['BODY'] = ob_get_contents();
ob_end_clean();
if(empty($Template) || empty($TemplateFields['BODY'])) {
// Let's not waste time doing nothing
} else {
foreach($TemplateFields as $Field => $Value) {
$Template = str_replace("<!-- %$Field -->", $Value, $Template);
}
print($Template);
}
}
function SetTemplateField($Field, $Value) {
global $TemplateFields;
if($Value === NULL && isset($TemplateFields[$Field]))
unset($TemplateFields[$Field]);
else
$TemplateFields[$Field] = $Value;
}
$Template = file_get_contents(dirname(__FILE__) . "/.template.html");
$TemplateFields['TITLE'] = "";
if(!empty($Template)) {
ob_start();
register_shutdown_function('_ProcessTemplate');
}
?>
Usage
Usage is as simple as including .template.php at the top of each page.
Example 1
example.php
<?php
require(".template.php");
SetTemplateField('TITLE','Welcome to my site!');
?>
<h1>Home</h1>
<p>This page is simple and just serves as an example for the templating engine.</p>
<hr />
<p>Thanks for visiting!</p>
Example 2
You can use whatever substitution fields you want in the templates. Just use SetTemplateField to set a value and it will be substituted for the tag when it occurs in the template.
.template.php
<html>
<head>
<title><!-- %TITLE --></title>
<link rel="icon" href="/favicon.ico" type="image/x-icon" />
<style>
BODY { text-align: center; font-size: 110%; }
</style>
<meta rel="author" content='<!-- %AUTHOR -->' />
</head>
<body>
<!-- %BODY -->
</body>
</html>
