If this happens,you will see an error similar to the following: Smarty能夠捕獲許多錯誤，比如缺少標簽屬性或者不規范變量名。如果發生這種錯誤，就會有類似下面的錯誤提示： <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 錯誤</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，語法錯誤:'%blah'標簽未知  Fatal error: Smarty: [in index.tpl line 28]: syntax error: missing section name in /path/to/smarty/Smarty.class.php on line 1041嚴重錯誤：Smarty: 在index.tpl文件第28行，語法錯誤:缺少節段名字在 /path/to/smarty/路徑中的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可以顯示模板名稱以及行號和錯誤。后面跟著包含這些錯誤在smarty類所在的實際行號。 Smarty不能捕獲某些錯誤，像缺少結束標簽。這類型的錯誤一般以php編譯時解析錯誤終止。 <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解析錯誤</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. 當你遇到一個php解析錯誤時，錯誤行號反映的php編譯腳本，而不是模板本身（雖然實際情況是模板有誤，但錯誤機制只反映在php編譯腳本）。一般情況下，你只須查看模板并發現錯誤語法。這里提供一些常見的錯誤：缺少{if}{/if}或者{section}{/section}的閉合標簽，或者{if}標簽內的邏輯語法錯誤。如果你不能在模板中發現錯誤，那就可能需要打開php編譯文件，然后查看行號，并返回模板找出相應的錯誤。 **Example 17.3.
