I need to make a small and simple php template engine I searched a lot and many of them were too complex to understand and I don't want to use smarty and other similar engines, I have got some idea from Stack Overflow like this:
$template = file_get_contents('file.html');
$array = array('var1' => 'value',
'txt' => 'text');
foreach($array as $key => $value)
{
$template = str_replace('{'.$key.'}', $value, $template);
}
echo $template;
Now instead of echo the template I just want to add include "file.html" and it will display the file with correct variable values and I want to put the engine in a separate place and just include it in the template what I want to use it declare the array and at the end include the html file like phpbb. Sorry I am asking to much but can anyone just explain the basic concept behind this?
EDIT: Well let me be frank i am making a forum script and i have got tons of ideas for it but i want make its template system like phpbb so i need a separate template engine custom one if you can help then please you are invited to work with me. sorry for the ad.. :p

PHP is not a template engine, but a language that can be used to write templates, or template engines. A template engine is not just a language, but also the programming API that allows the scripts to locate, organize templates or assign the data from the script to them.
A PHP template engine is a way of outputting PHP in your HTML without using PHP syntax or PHP tags. It's supposed to be used by having a PHP class that will send your HTML the variables you want to display, and the HTML simply displays this data.
Spring MVC, Struts or Apache Wicket are examples of web frameworks, whereas JSP, Velocity or FreeMarker are examples of template engines.
Popular template engines Template engines are mostly used for server-side applications that are run on only one server and are not built as APIs. The popular ones include Ejs, Jade, Pug, Mustache, HandlebarsJS, Jinja2, and Blade.
file.html:
<html>
<body>
<h3>Hi there, <?php echo $name ?></h3>
</body>
</html>
file.php:
<?php
$name = "Keshav";
include('file.html');
?>
Doesn't get simpler than this. Yes, it uses global variables, but if simple is the name of the game, this is it. Simply visit 'http://example.com/file.php' and off you go.
Now, if you want the user to see 'file.html' in the browser's address bar, you'd have to configure your webserver to treat .html files as PHP scripts, which is a little more complicated, but definitely doable. Once that's done, you can combine both files into a single one:
file.html:
<?php
$name = "Keshav";
?>
<html>
<body>
<h3>Hi there, <?php echo $name ?></h3>
</body>
</html>
What if, for a script easier to maintain, you move those to functions?
something like this:
<?php
function get_content($file, $data)
{
$template = file_get_contents($file);
foreach($data as $key => $value)
{
$template = str_replace('{'.$key.'}', $value, $template);
}
return $template;
}
And you can use it this way:
<?php
$file = '/path/to/your/file.php';
$data = = array('var1' => 'value',
'txt' => 'text');
echo get_content($file, $data);
