return $out;
}
}
?>
Test.php (the template)
Code:
Hello and welcome {user.username}!
Your last visit was {user.lastvisit} here on {site.name}!
Your postcount is: {user.posts.count}!
index.php
PHP Code:
<?php
require './template.php';
$tpl = new Template;
$tpl->parse('test', array(
'user' => array(
'lastvisit' => 'yesterday',
'username' => 'Sjaq',
'posts' => array('count' => 10)
),
'site' => array(
'name' => 'TalkPHP'
)
));
?>
(My indentation style is a bit inconsistent, I'm trying to adapt the BSD/Allman style) |
Wow, thanks!! I will study the code more carefully :D
Also one thing, does this also work with variables?
Like if I do:
Code:
You are currently on page {page}
And that would be replaced with the value of
???
THanks once again :) |
