The syntax is much the same a traditional template resource names. Smarty will first look for a registered template resource. If nothing is found, it will check if a PHP stream is available. If a stream is available, Smarty will use it to fetch the template. streams数据流允许你使用php数据流作为模板资源或变量资源。语法与传统的模板资源命名基本一样。 Smarty首先会搜索一个注册的模板资源。如果没找到，它会检查php数据流是否是一个变量，如果是，Smarty会将其从模板中取出使用。 <table width="80%" border="0" cellpadding="2" cellspacing="2" class="note"><caption> 提示 </caption> <tr><td>Note<br/> You can further define allowed streams with security enabled.<br/> 可以进一步启动安全策略定义允许的数据流。</td> </tr></table> <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td> <div class="EXAMPLE"> <p><strong><a name="AEN4158" id="AEN4158"> </a>Example 15.8.
