在上次发布的simplet类之后(http://bbs.phpchina.com/thread-85257-1-1.html),发现有很多缺陷,例如不支持多维数组,注释和没有缓存功能,这次我把这些功能都加进去了!!!
大家有兴趣的话,我下次出个教程,来谈谈我写这个类的一些思想和方法!!!支持的话可以跟贴支持我!
PHP代码:
simplet.class.php
class SimpleT {
   PRivate $t_vars;
   private $templates_dir;
   private $templates_c_dir;
   private $cache;
   private $cache_dir;
  
   public function __construct() {
     $this->templates_dir = './templates/';
     $this->templates_c_dir = './templates_c/';
     $this->cache = 0;
     $this->cache_dir = './cache/';
   }
   public function setDir($dir, $type = 'template') {
     if(is_dir($dir)) {
       if($type == 'template')
         $this->templates_dir = rtrim($dir, '/').'/';
       elseif($type == 'template_c')
         $this->templates_c_dir = rtrim($dir, '/').'/';
       elseif($type == 'cache')
         $this->cache_dir = rtrim($dir, '/').'/';
       else
         return false;
       return true;
     } else {
       return false;
     }
   }
  
   public function cache($time) {
     if(is_numeric($time)) {
       $this->cache = $time;
       return true;
     } else {
       return false;
     }
   }
  
   public function assign($var, $value = NULL) {
     if (is_array($var)) {
       foreach ($var as $key => $val) {
         $this->t_vars[$key] = $val;
       }
     } else {
       $this->t_vars[$var] = $value;
     }
   }
   private function comp($filename) {
     try {
       if(!$fp = fopen($filename, 'r')) {
         throw new Exception('Can not open ' . $filename);
       }
       $filesize = filesize($filename);
       if($filesize          throw new Exception('The file size must > 0 ' );
       }
       $content = fread($fp, $filesize);
       fclose($fp);
       unset($fp);
      
       $content = preg_replace("//","", $content);
       $content = preg_replace("//", " \\$$1_val) { ?>",$content);
       $content = preg_replace("//", "", $content);
       $content = preg_replace("//", " \\$$3) { ?>", $content);
       $content = preg_replace("//", "", $content);
       $content = preg_replace("//", "", $content);
       $content = preg_replace("//", "", $content);
       $content = preg_replace("//","", $content);
       $content = preg_replace("/([^]{0,})/", "", $content);
       if (preg_match_all("/)]{1,})}%>/", $content, $files)) {
         $this->comp($this->templates_dir . $files[1][0]);
       }
       $content = preg_replace("/)]{1,})}%>/", "templates_c_dir}simplet_comp_$1.php'; ?>", $content);
       echo $content;
       $fp = fopen($this->templates_c_dir . 'simplet_comp_' . basename($filename) . '.php', 'w');
       if(!fwrite($fp, $content)) {
         throw new Exception('Can not write content in the ' . $filename);
       }
       fclose($fp);
     } catch (Exception $e) {
       echo $e->getMessage();
     }
     return true;
   }
   public function display($filename) {
     $filename = $this->templates_dir . $filename;
     if(!file_exists($filename)) {
       return false;
     }
     $t_filename_c = $this->templates_c_dir . 'simplet_comp_' . basename($filename) .'.php';
     if(!file_exists($t_filename_c) || filemtime($t_filename_c)        $this->comp($filename);
     }
     if($this->cache > 0) {
       $cache_file = $this->cache_dir . basename($filename);
       if(!file_exists($cache_file) || (time() - filemtime($cache_file)) > $this->cache) {
         ob_start();
         foreach ($this->t_vars as $key => $val) {
           $$key = $val;
         }
         include($t_filename_c);
         $content = ob_get_contents();
         ob_end_clean();
         $fp = fopen($cache_file, 'w');
         fwrite($fp, $content);
         fclose($fp);
         echo $content;
         unset($content);
       } else {
         include($cache_file);
       }
     } else {
       foreach ($this->t_vars as $key => $val) {
         $$key = $val;
       }
       include($t_filename_c);
     }
    
   }
}
?>

PHP代码:
test.php

require_once('simplet.class.php');

$t = new SimpleT();
$t->cache(10);//开启cache功能,并且设置为过期时间为10秒
$t->assign('arrays', array(array('hello','world')));
$t->assign('condition',false);
$t->display('index.php');
?>

PHP代码:
index.php(模板文件,放在templates/文件夹里)


这里是注释
下面是多维数组循环


  
    
  


下面是条件判断


  

Condition is true



下面是包含文件()
