php的发展前景好吗
今天刚找的一家做php的公司,因为之前是干java方面的。但是刚毕业也不好找工作,无意中找了一家干php的。朋友们都不太看好,我也不知道怎么弄了。楼下的亲们,给点意见呗。或者帮我比较下你们身边的干三四年java与php的待遇优差多少。
------解决方案--------------------
php和java应该各有优势吧,也不能说的太死,php可能更轻松一些,java的应用领域会更广,就看自己想向什么方向发展了。
技术类赚钱多少要看个人技术水平和工作经验的,不是干多少年待遇就会高。是精通才会高,与语言关系不大。
我知道本科毕业生在百度做web开发(php)年薪都可以有13w-15w。没有最强的语言,只有最强的程序员。
讲xxx语言没前途的,都是没有学好xxx语言的。
------解决方案--------------------
Java本是没有前途的垃圾语言,虽然工资都很高。但Android出现救了他。
Java速度极慢。不适合做程序。都是大公司用来骗大公司钱的东西。
以PC应用来说。php开发的成本只有Java 2到10分之一的成本。虽然java很慢。但你只要像银行,电信一样有钱,买很贵很好的服务器,还是跑得起来的。
我2003年开始做Java编程.一年后基本所掌握了Java的所有东西。二年后,基本可以说非常精通了。因为之前就有几年C++编程经验。
Java是很简单的语言。难度大概只有php的3分之一。
Java语言虽然很差。但对后面编程界面思想的影响是非常大的。
php薪水比Java始终低一个等级。其实也不低啦,因为Java工作都非常高。再者因为php都是哭逼追求性价比的公司用的。所以工资不高。
Java你几乎做不了什么自己的东西。而php你几乎可以做你任何想做的web系统软件。而且开发速度好快。
如果你只打工Java比php强,如果你想创业,就学php吧。
语言,程序,软件,都是有高低的。说什么语言没有高低,只有人水平有高低的。大都是编程经验8年以下的菜鸟。
比如花5万元写的php+mysql web系统可以支持每天10万人访问。同样,你花5万写的Java jsp或者.net系统,可能只支持2-3万人访问还很慢,你说语言有没有高低?我们当时在华为编程,上万个java程序员,我见到过几百个。从来没有人不说java速度极慢的。说Java好的都是没有用过Java编程的菜鸟。Java语言第二发明者,Boland公司。用Java写的Jbuilder都极慢啊。何况底层还是C编程都极慢。
------解决方案--------------------
不管什么语言,还不是市场需要?
有需求,自然就有人学。
每一种语言后面,都有一堆人。
------解决方案--------------------
我也开始学的java,实习的时候无意中接触到了php的工作,后来找工作的时候java和php的工作都投了简历,结果是java都是外包的工作,不高兴去做外包,后来无意间一个上市公司招PHP,看了我的简历,给我打电话,很成功的面试成功。至今毕业两年,拿的工资也不比做java 的同学工资低,做自主产品研发,比同学他们都轻松多了。
其实什么语言都一样,关键你要精通了,工资都不是问题
------解决方案--------------------
我之前也是做java的,下周开始就去做php了.
我也不知道php怎样,最近几天在学,感觉和java很像,但又掺杂写面向过程的思想在里面.
我饺子吧,程序员不可能只会一种语言,php专业做web的,学了之后应该会对web开发提升一个层次.
PS:2楼的大哥,你第一句就说java是垃圾语言,然后后面又说'语言,程序,软件,都是有高低的。说什么语言没有高低,只有人水平有高低的。大都是编程经验8年以下的菜鸟。' ,敢问您是大牛还是菜鸟.....

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.

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 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.

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.

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 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 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.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
