不能确定这段代码在Framework上如何工作

					{if ($debug)}						SQL ({count($sql_log)})			DUMP ({count($dump)})			Profile ({$profile.time})							Time: {$profile.time} sec.
			Memory: {$profile.memory} bytes				{foreach name=dump from=$dump item=item}			Dump: {$item.file}:{$item.line}

回复讨论(解决方案)

应该不是HTML吧，HTML应该不支持
{if ($condition)}.............{/if}

{foreach name=sql_log from=$sql_log item=item}................{/foreach}

应该是 PHP，我猜 "!=" 也能工作，但不知为什么能这么写，同问！

smarty 模版！！
