Hej,
Använder en template class som ser ut såhär:
<?php
class Template {
var $vars; /// Holds all the template variables
/**
* Constructor
*
* @param $file string the file name you want to load
*/
function Template($file = null) {
$this->file = $file;
}
/**
* Set a template variable.
*/
function set($name, $value) {
$this->vars[$name] = is_object($value) ? $value->fetch() : $value;
}
/**
* Open, parse, and return the template file.
*
* @param $file string the template file name
*/
function fetch($file = null) {
if(!$file) $file = $this->file;
if(count($this->vars)>0) //My modification
extract($this->vars); // Extract the vars to local namespace
ob_start(); // Start output buffering
include($file); // Include the file
$contents = ob_get_contents(); // Get the contents of the buffer
ob_end_clean(); // End buffering and discard
return $contents; // Return the contents
}
function printVars() {
print_r($this->vars);
}
}
/**
* An extension to Template that provides automatic caching of
* template contents.
*/
class CachedTemplate extends Template {
var $cache_id;
var $expire;
var $cached;
/**
* Constructor.
*
* @param $cache_id string unique cache identifier
* @param $expire int number of seconds the cache will live
*/
function CachedTemplate($cache_id = null, $expire = 900) {
$this->Template();
$this->cache_id = $cache_id ? 'cache/' . md5($cache_id) : $cache_id;
$this->expire = $expire;
}
/**
* Test to see whether the currently loaded cache_id has a valid
* corrosponding cache file.
*/
function is_cached() {
if($this->cached) return true;
// Passed a cache_id?
if(!$this->cache_id) return false;
// Cache file exists?
if(!file_exists($this->cache_id)) return false;
// Can get the time of the file?
if(!($mtime = filemtime($this->cache_id))) return false;
// Cache expired?
if(($mtime + $this->expire) < time()) {
unlink($this->cache_id);
return false;
}
else {
/**
* Cache the results of this is_cached() call. Why? So
* we don't have to double the overhead for each template.
* If we didn't cache, it would be hitting the file system
* twice as much (file_exists() & filemtime() [twice each]).
*/
$this->cached = true;
return true;
}
}
/**
* This function returns a cached copy of a template (if it exists),
* otherwise, it parses it as normal and caches the content.
*
* @param $file string the template file
*/
function fetch_cache($file) {
if($this->is_cached()) {
$fp = fopen($this->cache_id, 'r');
$contents = fread($fp, filesize($this->cache_id));
fclose($fp);
return $contents;
}
else {
$contents = $this->fetch($file);
// Write the cache
if($fp = fopen($this->cache_id, 'w')) {
fwrite($fp, $contents);
fclose($fp);
}
else {
die('Unable to write cache.');
}
return $contents;
}
}
}
?>
Nu vill jag kunna lokalisera statiska texter/ord som finns i alla templates och tänker spara alla fraser i en XML-fil per språk. Sen har jag tänkt mig att varje ord som ska översättas skrivs som t.ex. {PHRASE_NAME} eller liknande.
Min idé är sen att alla ord som omges av {} hämtas i classen ovan, men osäker på hur funktionen skulle kunna se ut samt hur jag hämtar orden. Jag gissar att det ska in någonstans kring include(file) ovan.
Förslag tages tacksamt emot.
