模板引擎作为视图层和模型曾分离的一种解决方案。

首先我们新建一个Template.class.php 的文件 '.m', //设置模板文件'templateDir' => 'template/', //设置模板所在的文件夹'compileDir' => 'cache','debug' => false,//设置编译后存放的目录'cache\_htm' => true,//是否需要编译成静态的html文件'suffix\_cache'=> '.htm',//编译后的文件后缀'cache\_time' =>2000,// 多长时间自动更新'php\_turn' =>false,//是否支持原生的php代码'cache\_control' => 'control.dat',);private $compileTool;//编译器public $filename;//模板文件名称private $value =array();//值栈static private $instance = null;public $debug = array();//调试信息public function \_\_construct($arrayConfig =array())\{ //返回当前UNIX时间戳和微妙数$this->debug\['begin'\] = microtime(true);$this->arrayConfig =$arrayConfig+$this->arrayConfig;$this->getPath();if(!is\_dir($this->arrayConfig\['templateDir'\]))\{exit("template isnt not found");\}if(!is\_dir($this->arrayConfig\['compileDir'\]))\{mkdir($this->arrayConfig\['compileDir'\],0770,true);\}include("Compile.class.php");//$this->compileTool = new Compile;\}/\*\*路径处理为绝对路径\*/public function getPath()\{$this->arrayConfig\['templateDir'\] = strtr(realpath($this->arrayConfig\['templateDir'\]),'\\\\','/').'/';$this->arrayConfig\['compileDir'\] = strtr(realpath($this->arrayConfig\['compileDir'\]),'\\\\','/').'/';\}/\*\*\*单例模式获取模板的实例\*\*/public static function getInstance()\{if(is\_null(self::$instance))\{self::$instance = new Template();\}return self::$instance;\}public function setConfig($key,$value = null)\{if(is\_array($key))\{$this->arrayConfig = $key+$this->arrayConfig;\}else\{$this->arrayConfig\[$key\] = $value;\}\}public function getConfig($key = null)\{if($key)\{return $this->arrayConfig\[$key\];\}else\{return $this->arrayConfig;\}\}/\*\* 注入单个变量\*\*/public function assign($key,$value)\{$this->value\[$key\] = $value;\}/\*\* 注入多个变量\*\*/public function assignArray($array)\{if(is\_array($array))\{foreach($array as $k => $v)\{$this->value\[$k\] = $v;\}\}\}/\*\*\* 获取模板文件的路径\*\*/public function path()\{return $this->arrayConfig\['templateDir'\].$this->filename.$this->arrayConfig\['suffix'\];\}/\*\*\*是否需要缓存\*\*/public function needCache()\{return $this->arrayConfig\['cache\_htm'\];\}/\*\*\*是否需要重新生成缓存文件\*\*/public function reCache($file)\{$flag = false;//生成缓存文件$cacheFile = $this->arrayConfig\['compileDir'\].md5(@$filename).'.'.'php';//var\_dump($cacheFile);if($this->arrayConfig\['cache\_htm'\]===true)\{//设置timeflag (判断当前时间-模板文件上次修改的时间)是否小于设置的缓存时间//如果小于则返回TRUE$timeFlag = (time()-@filemtime($cacheFile))arrayConfig\['cache\_time'\]?true:false;//1，判断缓存文件是否存在，//2，缓存文件是否有内容//3，时间是否在设置的缓存时间之内if(!is\_file($cacheFile)&&filesize($cacheFile)>1&&$timeFlag)\{$flag = true;\}else\{$flag = false;\}\}return $flag;\}/\*\*\*显示模板\*\*/public function show($file)\{$this->filename =$file;if(!is\_file($this->path()))\{exit('找不到相对应的模板');\}$compileFile = $this->arrayConfig\['compileDir'\].'/'.md5(@$filename).'.php';$cacheFile = $this->arrayConfig\['compileDir'\].md5(@$filename).'.htm';//echo $compileFile;//echo $cacheFile;if($this->reCache($file)===false)\{$this->debug\['cached'\] = 'false';//var\_dump($compileFile);$this->compileTool = new Compile($this->path(),$compileFile,$this->arrayConfig);if($this->needCache())\{//是否需要缓存ob\_start();\}//函数从数组中把变量导入到当前的符号表中extract($this->value,EXTR\_OVERWRITE);//判断 文件是否存在，生成文件的修改时间是否小于模板文件修改时间if(@is\_file($compileFile)||filemtime($compileFile)path()))\{$this->compileTool->vars = $this->value;$this->compileTool->compile();//引入文件include $compileFile;\}else\{include $compileFile;\}if($this->needCache())\{//如果需要缓存的话$message = ob\_get\_contents();//则生成缓存文件file\_put\_contents($cacheFile,$message);\}\}else\{//如果缓存文件时间小于设定的时间//直接读取缓存文件readfile($cacheFile);//$this->debug\['cached'\] = true;\}$this->debug\['spend'\] = microtime(true) - $this->debug\['begin'\];$this->debug\['count'\] = count($this->value);$this->debug\_info();/\*var\_dump($compileFile);thisvar\_dump($this->path());if(!is\_file($compileFile))\{mkdir($this->arrayConfig\['compileDir'\]); //此处若存在需要判断$this->compileTool->compile($this->path(),$compileFile);readfile($compileFile);\}else\{readfile($compileFile);\}\*/\}/\*\*\*debug 调试函数\*\*/public function debug\_info()\{//$this->arrayConfig\['debug'\]=false;if($this->arrayConfig\['debug'\]===true)\{var\_dump($this);echo "程序运行日期",date("Y-m-d h:i:s")."";echo "模板解析耗时",$this->debug\['spend'\],'秒'."";echo "模板包含标签数目",$this->debug\['count'\]."";echo "是否使用静态缓存",$this->debug\['cached'\]."";//echo "模板引擎实例参数",var\_dump($this->getConfig());\}\}/\*\*\*\*\*\*清楚缓存的文件\*\*\*\*\*/public function clean($path = null)\{if($path = null)\{$path = $this->arrayConfig\['CompileDir'\];$path = glob($path.'\*'.$this->arrayConfig\['suffix\_cache'\]);//glob 函数返回匹配指定的文件夹目录\}else\{$path = $this->arrayConfig\['compileDir'\].md5($path).'.htm';foreach((array)$path as $v)\{//删除unlink($v);\}\}\}\}

新建一个 Compile.class.php 翻译模板文件 template = $template;$this->comfile = $compileFile;$this->content = file\_get\_contents($template);if($config\['php\_turn'\]===false)\{//echo "123";//$this->T\_R\[\]="";\}//echo "123";//正则匹配 \{$xxx\} 格式$this->T\_P\[\]="\#\\\{\\\\$(\[a-zA-Z\_\\x7f-\\xff\]\[a-zA-Z0-9\_\\x7f-\\xff\]\*)\\\}\#";$this->T\_R\[\]="value\['\\\\1'\];?>";\}public function compile()\{$this->c\_var2();//$this->c\_staticFile();//var\_dump($this);file\_put\_contents($this->comfile,$this->content);\}public function c\_var2()\{// 将\{$xxx\} 替换为$this->content = preg\_replace($this->T\_P,$this->T\_R,$this->content);\}public function c\_staticFile()\{$this->content =preg\_replace('\#\\\{\\!(.\*?)\\!\\\}\#','',$this->content);\}public function \_\_set($name,$value)\{$this->$name = $value;\}public function \_\_get($name)\{return $this->$name;\}\}

新建一个测试文件 test.php false,'debug'=>false));$tpl->assign('data','hello world');$tpl->show('member');//var\_dump($tpl->getConfig());

模板文件member.m welcome\{$data\}
