HomeBackend DevelopmentPHP TutorialThinkPHP3.1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}!');

页面输出的结果是:

hello,ThinkPHP!

你也可以采用读取数据库的方式:

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

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');

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。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
