写phpd的我。最近公司要弄个app关键是没有web开发，而我有比较闲，那就扛枪上阵吧。

响应式布局，web端的？php我一直都是用tp框架，对于web首先想到的是bootstrap框架。只是简单了解过，没真正实践啊，bootstrap比我想象的要好用的多。关键是，关键来了……

app端是只有手机的，pc基本上木有。那就是说只能按照手机端开发，那么boostrap响应式布局就不适用于app了（反正我是做了一套半成品，被推翻了）。不能愉快的工作了，好不淡定的时间。。百度，百又问问同事，发现了amaze ui也就是妹子框架，终于可以省事了，太高兴了。

amaze框架下载后是一套让人极其郁闷的示例包，文件引入是分开来介绍的，如果你不仔细看文档，会很痛苦的（因为我就是如此，好折磨人）。

好了附上amaze的引入文件，仅供大伙参考。

对了手机端要在头部加上这句话

一切就绪，那就直奔主题。

手机端目前最低宽度是300.不过说实话智能手机300的屏幕估计是木有，那就按iphone4的320来设计web。那么问题来了，设计给的参考图示640的肿么办，所有的像素除以2，一切解决。

使用amaze框架并不能很好的解决不同分辨率的像素问题，而且最苦逼的就是要设置好多@media only screen and (min-width:320px) and (max-width:480px) {}屏幕范围样式。太痛苦了，受不了。。有木有一种可以控制的方法呢，京东是怎么弄的？小米又是怎么弄的？百度吧，一切从度娘中找答案。

答案好多，慢慢筛选吧……

于是找到这段代码

那么问题来了，这只是页面的，我想要所有的地方在不同尺寸的浏览器都能自适应，怎解决？

clientwidth是获取屏幕显示的宽度，设定最小屏幕为320，以320为基础，那么最小最字体就是12px。于是就有了改动。

好了这下子无论什么浏览器都是以最宽320，最小12px为基准。接着还有个问题，所有布局改用什么单位？px/em/pt/rem

px是最精确的单位,固定值。em值不固定，继承父元素。rem在设定元素时仍是相对大小，但相对的是html根元素。pt就是印刷业上的单位，不过app开发中也用到。

那么好了，该用哪种的呢，我们先来看看上面的自适应js执行效果。

在html元素中生成了一个行内字体样式，答案就有了吧。

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.

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AM

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AM

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
