PW没有使用当下流行的php模板引擎如Twig、smarty，而是采用的php原生语法，这极大程度地降低了学习成本并提高了开发效率和可维护性，下面是官方提供的和ExpressionEngine CMS模板引擎语法对比的代码片段。

示例一

ExpressionEngine

{embed=layout/header}
   <h1>{exp:channel:category_heading channel="reviews"}{category_name}{/exp:channel:category_heading}</h1>
   {exp:channel:entries channel="reviews"}
      <article class="review">
         <h2><a href="{url_title_path=reviews}">Reviews in {title}</a></h2>
         <p class="meta">Posted on {entry_date format="%Y %m %d"}</p>
         <p>{content}</p>
      </article>
   {/exp:channel:entries}
{/embed=layout/footer}

ProcessWire 示例代码一：内容完全由php输出

include("header"); 
   e("<h1>{$page->category->title}</h1>");
   foreach($pages->find("parent=/reviews/") as $review) e("
      <article class='review'>
         <h2><a href='{$review->url}'>Reviews in {$review->title}</a></h2>
         <p class='meta'>Posted on {$review->date}</p>
         <p>{$review->content}</p>
      <article>");
include("footer"); 

注意：{$review->date}输出日期的格式可在后台设置，在模板中直接输出

ProcessWire示例代码二：HTML混合php语法

（功能同上，大多数人选择这种语法，但个人更喜欢前者）

<? include("./header.inc"); ?>
   <h1><?=$page->category->title?></h1>
   <? foreach($pages->get("/reviews/")->children() as $review: ?>
   <article>
      <h2><a href="<?=$review->url?>">Reviews in <?=$review->title?></a></h2>
      <p class="meta">Posted on <?=$review->date?></p>
      <p><?=$review->content?></p>
   </article>
   <? endforeach; ?>
<? include("./footer.inc"); ?>

示例二

ExpressionEngine

{exp:channel:entries channel='faq'}
    {if count == 1}
        <ul>
    {/if}
    <li><a href="{title_permalink=faq/entry}">{title}</a></li>
    {if count == absolute_results}
        </ul>
    {/if}
    {if no_results}
        <h1>No entries found</h1>
    {/if}
{/exp:channel:entries}

ProcessWire

$li = '';
foreach($pages->find("parent=/faq/") as $e)
    $li .= "<li><a href='{$e->url}'>{$e->title}</a></li>";
echo $li ? "<ul>$li</ul>" : "<h1>No entries found</h1>";
