That was a mistake on my part, it is loaded into a string.

The problem is that, I have no problem replacing the keyword with the
proper php syntax for a loop or whatever, the problem is that it just
shows up as a string when all is said and done.
If you want to see the code I have right now, here it is (below). I'm
thinking I'm going to have to combine the load() and run() methods,
and then make assign() create an array of stuff that must be assigned,
then do pretty much all the work in the combined method or load() and
run(). That probably sounded pretty confusing, I hope you understand
what I'm sayin.
<?php
class tpl {
//
// PRIVATE CLASS VARIABLES
//
var $file;
var $template;
var $compiled;
//
// LOAD A TEMPLATE FILE
//
function load($template) {
$this->template = 'tpl/' . $template . '.tpl';
$this->compiled = 'compiled/' . $template . '.tplc';
if (file_exists($this->template) && filemtime($this->template) >
filemtime($this->compiled)) {
$file = fopen($this->template,'r');
$this->file = fread($file,filesize($this->template));
fclose($file);
} elseif (file_exists($this->compiled) &&
filemtime($this->template) < filemtime($this->compiled)) {
readfile($this->compiled);
} else {
print('</p>' . $this->template . ' Does not exist</p>');
}
}
//
// ASSIGN THE VARIABLES
//
function assign($var,$value) {
if (isset($var) && isset($value)) {
$this->file = str_replace('{' . $var . '}',$value,$this->file);
}
}
//
// DISPLAY THE TEMPLATE
//
function run() {
if (filemtime($this->template) > filemtime($this->compiled)) {
$file = fopen($this->compild,'w');
fwrite($file,$this->file);
fclose($file);
readfile($this->compiled);
}
}
}
?>
