思路:
欲在速度和易用(主要指的是美工设计的方便性)之间取得一个平衡点.于是采用了由html文件生成php文件的办法(编译?)
也想在分离显示逻辑和分离html代码之间平衡一下

例如一个论坛首页(index.php):

代码:

require('./template.php');
//由html生成的php文件的前缀,区别使用多种风格.
$tpl_prefix = 'default';
//模板文件名
$tpl_index = 'index';

$tpl = new Template($tpl_prefix);

$cats = array(
array('forum_id'=>'1','forum_cat_id'=>'0','forum_name'=>'PHP学习'),
array('forum_id'=>'2','forum_cat_id'=>'0','forum_name'=>'MYSQL学习')
);
$forums = array(
array('forum_id'=>'3','forum_cat_id'=>'1','forum_name'=>'PHP高级教程'),
array('forum_id'=>'4','forum_cat_id'=>'1','forum_name'=>'PHP初级教程'),
array('forum_id'=>'5','forum_cat_id'=>'2','forum_name'=>'MYSQL相关资料')
);

if ($cats)
{
if ($tpl->chk_cache($tpl_index))//检查判断是否需要重新生产PHP模板文件.
{
   $tpl->load_tpl($tpl_index);//加载html模板文件.
   //替换PHP语句
   $tpl->assign_block("{block_cat}","");
   $tpl->assign_block("{/block_cat}","");
$tpl->assign_block("{block_forum}","
\nif(\$forum['forum_cat_id'] == \$cat['forum_id']) {?>");
   $tpl->assign_block("{/block_forum}","");
   //生产PHP模板文件.
   $tpl->write_cache($tpl_index);
}
}
//包含PHP模板文件.
include($tpl->parse_tpl($tpl_index));
?>

对应的html模板文件(index.html):

代码:

{block_cat}

{block_forum}

{/block_forum}

{=$cat['forum_name']}
{=$forum['forum_name']}

{/block_cat}

经过处理,里面的{block_forum}{block_cat}标签被替换成PHP循环语句,用于显示数组种所有元素.

生成的PHP模板文件(default_index.php):

代码:

if($forum['forum_cat_id'] == $cat['forum_id']) {?>

}?>

default_index.php is included in index.php, so that it can be displayed normally.

In this way, the HTML template file can be modified and beautified with dw, which should be more convenient for artists.

template.php

Code:

/***************************************************** *****************************

class Template {

//$this->$template, stores template data.
var $template = '';

//Template path.
var $tpl_path = '';

//Template prefix (style name).
var $tpl_prefix = '';

//cache path (compiled path).
var $cache_path = '';

//css file path.
var $css_path = ' ';

//header file path.
var $header_path = '';

//footer file path
var $footer_path = '';

/**

//Template file path.
$this->tpl_path = './templates/' . $root . '/';
//Generated PHP file storage path.
$ this->cache_path = './template_data/' .$this->tpl_prefix . '_';
return true;
}

/**

*/
function chk_cache($tpl_index)
{
$tpl_file = $this->tpl_path . $tpl_index . '.html';
$cache_file = $this->cache_path . $tpl_index . '. php';
//Determine whether it needs to be updated.
if(!file_exists($cache_file))
{
} return true;
}
elseif(filemtime($tpl_file) & gt ; filemtime($cache_file))
{ ='')
{
return $this->cache_path . $tpl_index . '.php';
}

/**

*/
function load_tpl ($tpl_index)
{
$tpl_file = $this->tpl_path . $tpl_index . '.html';
$fp = fopen($tpl_file, 'r');
$this ->template = fread($fp, filesize($tpl_file));
fclose($fp);
}

/**
* Load template file.
*/
function write_cache( $tpl_index)
{

$cache_file = $this->cache_path . $tpl_index . '.php';

//Variable display.
$this-> template = preg_replace("/({=)(.+?)(})/is", "", $this->template);

// Interface language replacement.
$this->template = preg_replace("/{lang +(.+?)}/ies", "$lang['main']['\1']", $this- >template);

$fp = fopen($cache_file, 'w');
flock($fp, 3);
fwrite($fp, $this->template) ;
fclose($fp);
}

/**
* Replace block.
*/
function assign_block($search,$replace)
{
$this->template = str_replace($search,$replace,$this ->template);
}
}
