Smarty notes, smarty
Smarty is often used in projects, but the simple assgin display foreach if else and other methods are always used. I watched smarty again when I had some free time. Simply record what is useful.
<br /> <span>smarty 系统保留变量 </span><span>$smarty</span>.<span>get #使用方法 $smarty.get.id 下面的一次类推 </span><span>$smarty</span>.<span>post </span><span>$smarty</span>.<span>session </span><span>$smarty</span>.<span>cookie </span><span>$smarty</span>.server<br /><br /> smarty模板中使用PHP中定义的常量<br /> php 文件中定义 define('HIEGHT', 8846);<br /> 模板文件中使用 $smarty.const.HIEGHT<br /><br /> smarty读取配置文件中的变量<br /> 1 $smarty->config_dir = "./conf"; #设置配置文件的路径<br /> 2 配置文件的书写规则 1)配置文件以.conf 结尾 2)配置文件内的书写规则 key1=val1 key1=val1 <br /> 3 使用:在模板文件的头部 {config_load file='site.conf'} <br /> 4 {$smarty.config.site} 即可获取 // {#site#}也可以读取<br /><br /> smarty缓存设置<br /> $smarty->caching = true; #开启缓存 缓存页面<br /> $smarty->cache_lifetime = 3600; #缓存的时间<br /> $smarty->cache_dir = './cache'; #存放换文件的目录 <br /> $smarty->isCached('news.html') 可以判断是否生成了缓存文件 #smarty3里面这么判断<br /> <br /> #一个页面生成多个缓存文件 例子:一个商品详情的页面 根据商品的ID 展现不同的内容 <br /> $id = empty($_GET['id]) ? 1 : $_GET['id'];<br /> $good_name = 'good_name_' . $id;<br /> $smarty->assign('good_name',$good_name);<br /> $smarty->display('tpm.html',$id); # 这样就会根据id生成不同的页面 。 <br /> 注意: 实际的项目中 这个ID 应该是根据参数算出来的。例如根据page,category等参数计算出来。之前公司的一个项目用到了smarty的缓存,这个id的值就是根据page category md5以后得到的。 ecshop中也是这么做的 不过不是MD5。<br /><br /> #清除缓存<br /> $smarty->clearCache('tmp_name')<br /> $smarty->clearAllCache() <br /> <br /> #设置局部不缓存的方法<br /> 1 在标签中 {$time|date_format:"%Y-%M-%D %H:%M:%S" nocache}<br /> 2 {nocache}{/nocache} 控制局部不缓存<br /> 3 php赋值的时候控制不缓存 assign 的第三个参数 设置为true <br /> 4 smarty中的一个insert方法 不细说 感觉没啥用 (囧)
######个人感觉smarty的缓存意义不太大。因为完全可以用redis MEMCHACHE 代替。当然存在即合理 哈哈 <br /><br /><br /> <br /> #变量调节器 :简单说 修改变量的展示形式的功能 例如:
{$time|date_format:"%Y-%M-%D %H:%M:%S" nocache}<br /><br /> #自己也可以写变量调节器 参照plugin里面的文件写就可以了 ###感觉有用。我们的项目中用到了。具体的使用,回头补上。<br /><br /><br />

2 Get it through composer: Composer is a very good thing.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
