前段时间,一直比较关心php的模板技术的我,接到了客户的要求:全站利用模板技术,可以控制多模板,这个项目要求有强大的后台,主要是多模板,难点就在模板的导入和识别并且生成上,我仔细考察了php的模板核心技术,无外乎查找字符串开始,然后定义替换变量,替换成数据,然后并成输出页输出,牵扯到的缓存我就不再说了.

我们来看看这种方式的生成方式的缺点:如果要"多样式"的显示数据,当然我先不说CSS,不能真正的把数据和表示分离,无外乎利用css样式表方式显示而已,我们现在接到的这个项目不但要求css样式表的可选化,而且要求数据显示的"多方式",打个比方,看下图:

模板用xml的思路_PHP

我们下面为了容易描述期间,我这样表示各个部分:A,B,C,D,E,F,G这6个区可以表示数据显示区域,从设计者角度考虑,有全局(div控制A-G),TOP(A),LEFT(B),RIGHT(C,D,E,F)和FOOTER(G),当然,您可以分的更细一些,这么显示,可以用div控制的,但这不是模板技术,请明白,多样式表不叫模板,这和模板无关,所谓的模板,就是只与"数据布局"相关,在A数据我们另外可以表示成一个导航,如果您喜欢的话.这在传统的模板技术中会这样写:

...

{$SITE_TOP$}//cjjer制作

...

替换的时候replace()的是{$ 和$}符号中的变量,这在数据简单的时候,比方只是一个导航,而我们如果要的是一个很复杂的数据显示的时候,那就很难控制了,因为把一个很大量输出数据放在一个变量中很难保证不出错.

另外,传统的模板(在php中)是这样的,获取模板的文件,加载,显示,这没什么问题,问题就在当web项目(不完全是网站)非常复杂的时候,很容易替换错误和模板单调,虽然可以用css控制一些显示,但很难控制数据的布局,比方,E区我今天不想要了,你改模板,重新加载文件... ?

有没有更加容易的解决方案?有.

我提出了这样一种观点:

模板页为 XML文档 ,模板节点加载已有模块 ,加载"仿xml数据"生成文件 (原谅我,这么说我觉得已经非常容易了)下面我就这种模板技术详谈.

先看看我说的模块是什么东西,大家都知道,html中的

呀,都是显示数据布局的一些布局标签,为什么我们不能自己制作这种标签呢?例如:我现在"创"一个这样的标签这里,当然,这个标签对项目是有意义的,表示控制全局的模块节点,如果在模板页中出现节点加载的就是对应名称为 format 的模块数据:

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.
