Question

Including template files and dynamically changing variables within them

Answer 1

A:

The simplest thing to do is something like this:

<?php
function IncludeHeader($title)
{
    echo str_replace('{PAGE_TITLE}', $title, file_get_contents('header.html'));
}
?>

Answer 2

A:

As you may understand, PHP is, itself, a template engine. That being said, there are several projects that add the type of templating you're describing. One which you might want to investigate is Smarty Templates. You might also want to check out the article published at SitePoint describing templating engines in general.

Answer 3

+1 A:

In the interests of keeping things simple, why not just use .php files with PHP shorttags instead of {PAGE_TITLE} or the like?

<html>
<head>
    <title><?=$PAGE_TITLE?></title>
</head>
<body>

Then, to isolate the variable space, you can create a template load function which works like this:

function load_template($path, $vars) {
    extract($vars);
    include($path);
}

Where $vars is an associative array with keys equal to variable names, and values equal to variable values.

Why not just use php?

    <title><?=$pageTitle; ?></title>
</head>
<body>

Answer 5

A:

This is the trick I've seen some frameworks use:

// Your function call
myTemplate('header',
    array('pageTitle' => 'My Favorite Page',
          'email' => '[email protected]',
    )
);

// the function
function myTemplate($filename, $variables) {
    extract($variables);
    include($filename);
}

// the template:
<html>
<head>
    <title><?=$pageTitle?></title>
</head>
<body>
    Email me here<a href="mailto:<?=$email?>"><?=$email?></a>
</body>
</html>
