ThinkPHP3.1新特性之内容解析输出详解_php实例

以往版本的ThinkPHP中页面输出的过程是读取模板文件,然后进行模板解析(也支持调用第三方模板引擎解析),但是有一些情况,我们并没有定义模板文件,或者把模板文件保存在数据库里面,那么这种情况下进行页面输出的时候,我们是无法进行模板文件读取的,ThinkPHP3.1版本则针对这样的情况增加了内容解析输出的功能。

内置的模板引擎也进行了完善,如果传入的模板文件不存在的话,则会认为是传入的模板解析内容,因此,ThinkPHP3.1版的View类和Action类也做了一些相应的改进。

display方法用于模板文件渲染输出,show方法则用于模板内容渲染输出,并且show方法仍然支持内容解析功能,因此,我们可以在控制器中这样使用:

$this->assign('name','ThinkPHP');
$this->show('hello,{$name}!');

Copy after login

页面输出的结果是:

hello,ThinkPHP!

Copy after login

你也可以采用读取数据库的方式:

$content = M('Data')->where($map)->getField('content');
$this->show($content);

Copy after login

对于$content变量中的内容,可以和模板文件一样支持变量和标签库的解析,并且也可以支持模板布局功能。
show方法也可以指定输出编码和类型,例如:

$this->show($content,'utf-8','text/xml');

Copy after login

总之,有了show方法后,可以把模板放数据库中,对于模板的管理和更新也更加方便了。
