Template file:

The code is as follows

<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "HTTP://WWW.W3.ORG/TR/HTML4/LOOSE.DTD" >
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 ">

{$article _title}
<br/>
--by {$author}
<br/>
{$content}
<br/>
--publish @ {$time}

<br/>

foreach test:

{foreach (From=url key=b item=c)}
<a href= "Index.php?artcle_id={==b}" >{==c}</a>
{/foreach}

<br/>

</body>

Parsing Engine:

The code is as follows
//Var


$pattern _var = "/{$left _tag}$ ([wd]+) {$right _tag}/";


$replace _var = ' &lt;?php echo $this-&gt;var_tpl_arr["$";? &gt; ';


  


if (Preg_match ($pattern _var, $content)) {


$content = preg_replace ($pattern _var, $replace _var, $content);


  }


  


//foreach


Preg_match_all ("/{$left _tag}foreachs+" ([^{]+?) {$right _tag}/is ", $content, $match _foreach);


if (isset ($match _foreach[1]) &amp;&amp; Is_array ($match _foreach)) {


foreach ($match _foreach[1] as $match _key =&gt; $match _value) {


$split _foreachs = Array_filter (Preg_split ('/s+/is ', $match _value));


$new _foreach_tag = Array ();


foreach ($split _foreachs as $split _foreach) {


$split = explode ("=", $split _foreach);


if (count ($split = = 2)) {


if (In_array ($split [0], array ("from", "Item", "key")) {


//Filter label does not exist filter


$new _foreach_tag[$split [0]] = $split [1];


      }


     }


    }


    


$from = $key = $item = ';


Extract ($new _foreach_tag);


$key = ($key)? ' $ '. $key. ' =&gt; ': ';


$replace _foreach = ' &lt;?php foreach ($this-&gt;var_tpl_arr['. $from. '] as '. $key. ' $ '. $item. ') {?&gt; ';


$content = str_replace ($match _foreach[0][$match _key], $replace _foreach, $content);


    


   }


  }


  


$pattern _foreach = "/{$left _tag}/foreach{$right _tag}/";


$replace _foreach = "&lt;?php}?&gt;";


if (Preg_match ($pattern _foreach, $content)) {


$content = preg_replace ($pattern _foreach, $replace _foreach, $content);


  }


  


//var in statement


$pattern _var = "/{$left _tag}== ([wd]+) {$right _tag}/";


$replace _var = ' &lt;?php echo $$1;? &gt; ';


  


if (Preg_match ($pattern _var, $content)) {


$content = preg_replace ($pattern _var, $replace _var, $content);


  }

<br/>
<?php echo $this->var_tpl_arr["content"];?
<br/>
-publish @ <?php echo $this->var_tpl_arr["Time"];?

<br/>
<br/>
foreach test:

<?php foreach ($this->var_tpl_arr["url"] as $b =& Gt $c) {
 <a href= "index.php?artcle_id=<?php echo $b;? > "><?php echo $c;? ></a>
<?php}

<br/>

</body>
