If this happens,you will see an error similar to the following: Smarty能够捕获许多错误，比如缺少标签属性或者不规范变量名。如果发生这种错误，就会有类似下面的错误提示： <table class="EXAMPLE" cellspacing="0" cellpadding="0" width="100%" border="0"><tbody><tr><td> <div class="EXAMPLE"><a name="AEN4189"/> <b>Example 17.1. Smarty errors<br/> 例17-1.Smarty 错误</b> <table width="100%" bgcolor="#e0e0e0" border="0"><tbody><tr><td><pre class="PROGRAMLISTING">Warning: Smarty: [in index.tpl line 4]: syntax error: unknown tag - '%blah' in /path/to/smarty/Smarty.class.php on line 1041警告：Smarty: 在index.tpl文件第4行，语法错误:'%blah'标签未知  Fatal error: Smarty: [in index.tpl line 28]: syntax error: missing section name in /path/to/smarty/Smarty.class.php on line 1041严重错误：Smarty: 在index.tpl文件第28行，语法错误:缺少节段名字在 /path/to/smarty/路径中的Smarty.class.php文件1041行</pre></td></tr></tbody></table></div></td></tr></tbody></table> Smarty shows you the template name, the line number and the error. After that, the error consists of the actual line number in the Smarty class that the error occured. There are certain errors that Smarty cannot catch, such as missing close tags. These types of errors usually end up in PHP compile-time parsing errors. Smarty可以显示模板名称以及行号和错误。后面跟着包含这些错误在smarty类所在的实际行号。 Smarty不能捕获某些错误，像缺少结束标签。这类型的错误一般以php编译时解析错误终止。 <table class="EXAMPLE" cellspacing="0" cellpadding="0" width="100%" border="0"><tbody><tr><td> <div class="EXAMPLE"><span class="PROGRAMLISTING"><strong>Example 17.2. PHP parsing errors</strong></span><br/><strong>例17-2.php解析错误</strong><table width="100%" bgcolor="#e0e0e0" border="0"><tbody><tr><td><pre class="PROGRAMLISTING">Parse error: parse error in /path/to/smarty/templates_c/index.tpl.php on line 75</pre></td></tr></tbody></table></div></td></tr></tbody></table> When you encounter a PHP parsing error, the error line number will correspond to the compiled PHP script, NOT the template itself. Usually you can look at the template and spot the syntax error. Here are some common things to look for: missing close tags for {if}{/if} or {section}{/section} , or syntax of logic within an {if} tag. If you can't find the error, you might have to open the compiled PHP file and go to the line number to figure out where the corresponding error is in the template. 当你遇到一个php解析错误时，错误行号反映的php编译脚本，而不是模板本身（虽然实际情况是模板有误，但错误机制只反映在php编译脚本）。一般情况下，你只须查看模板并发现错误语法。这里提供一些常见的错误：缺少{if}{/if}或者{section}{/section}的闭合标签，或者{if}标签内的逻辑语法错误。如果你不能在模板中发现错误，那就可能需要打开php编译文件，然后查看行号，并返回模板找出相应的错误。 **Example 17.3.
