在网站开发方面,java和php各自的优劣势是什么?
有朋友跟我说java可以跨平台,php快,但是太简略了,能否说的详细一点?
回复内容:
JAVA 的跨平台在单纯的网页开发中没有任何用处,用在客户端程序上倒是个不错的特性,它自己宣称的特性是 “编写跨平台应用软件的面向对象的程序设计语言”劣势方面,JSP 太难处理 UI 了……每次编译都想揍人
优势方面,框架齐备,性能较好(相对 PHP )。比如 SSH 基本人手必读,初学者也能玩玩;JAVA 处理复杂事务时总能有合适的解决方案,横向扩展负载均衡也好、与其他语言集成也好,都很成熟。
PHP 快在项目管理方面,上手快,开发快,组建团队快,成员补充快,唯独在工程效率上慢,特别是产品做大以后,PHP 乱糟糟的特性几乎必定成为做大做强的阻碍,代码组织上非常难于管理。
现在不少 PHP 框架都在搬运 JAVA 成熟框架的理念,比如国内有 ThinkPHP,国外有 CakePHP ,等等,鲜有特立独行或集大成的框架。不过这可能与处理深度有关,PHP 从业者较少面对海量压力(实际上也确实面对不了),没有这个大环境。
大体而言,JAVA 就像一个修车厂,工具齐全,什么都能做,但如果你只是想给轮胎打个气,就太浪费了。PHP 就像一个随车工具包,只有不多的几种工具,谁都会用,带着也方便,但如果要大修,这点工具还不够塞牙缝的。
顺便吐槽:
这题的问法非常不好,极易引起 “程序语言种族主义者” 的群嘲群攻、地图炮。如果可能的话,还请题主咨询一下身边认识的牛人,或者去 Stackflow 上旁观一下两类语言的热点问题和难点,大致就能了解到各自的短板和优势了。 php修改起来灵活 适合做web java可以用来做后端一些关键的组件 用java来做网站 真是折磨人 java的桌面gui早就没落了,
java跟php虽然都是做服务端,
但是java更偏向于服务,php更偏向于展现。
另外,php快是因为它做的事情简单,如果跟java做同样的事情,真不如java快

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
