自己默写smarty模板引擎,不解析php呢(求高手帮忙)
$realcontent =$this->filecontent;
$mode = '/\{\$([\w]+)\}/';
if(preg_match($mode,$realcontent)){
var_dump($assign_vars);
$realcontent=preg_replace($mode,"assign_vars['$1'] ?>",$realcontent); ;//替换成index.php文件中注入的变量
}
return $realcontent;
}
运行后代码为
assign_vars['content'] ?>
作者:assign_vars['name'] ?>assign_vars['var'] ?>

你只产生了 php 代码，并没有执行他
