PHP自定义函数实现assign()数组分配到模板及extract()变量分配到模板功能示例

class base{  public $array;  public $key;  public $val;  public function assign($key,$val){    if(array($val)){      $this->array["$key"] = $val;    }else{      $this->array["$key"] = compact($val);    }  }  public function display($tpl){    $this->assign($this->key,$this->val);    extract($this->array);    if(file_exists($tpl)){ //模板存在就加载文件。      include $tpl;    }  }}class indexcontroller extends base{  public function index(){    $arr = array('a'=>'aaaaaaa','b'=>array('a'=>'111111','b'=>'22222','c'=>'3333'),'c'=>'ccccccc','d'=>'dddddd','e'=>'eeeee');    $str = '我是字符串';    $this->assign('arr',$arr);    $this->assign('str',$str);    $this->display('index.html');  }}$base = new base;$base->index();
