Open source PHP development frameworks include Laravel, Symfony, CodeIgniter, Yii, Phalcon and CakePHP. 1. Laravel, which provides simple and elegant syntax, and a rich feature set, including database migration, authentication, caching, queues, etc.; 2. Symfony, which provides a set of powerful tools and components, including routing, forms, security performance, caching, database abstraction, etc.; 3. CodeIgniter provides a simple and easy-to-use API and rich functions.

When developing web applications, it is very important to choose a suitable development framework. The open source PHP development framework has many advantages, which can reduce code duplication, improve development efficiency, and enhance the maintainability and scalability of applications. The following are some commonly used open source PHP development frameworks:
1. Laravel: Laravel is one of the most popular PHP development frameworks. It provides a concise and elegant syntax, and a rich feature set, including database migration, authentication, caching, queuing, and more. Laravel also introduces the MVC (Model-View-Controller) pattern to make development more structured and maintainable.
2. Symfony: Symfony is a mature PHP development framework that can be used to build large and complex web applications. It provides a powerful set of tools and components, including routing, forms, security, caching, database abstraction, and more. Symfony also follows the MVC pattern, providing flexible configuration and scalability.
3. CodeIgniter: CodeIgniter is a concise and lightweight PHP development framework suitable for rapid development of small projects. It provides an easy-to-use API and rich functions, including database abstraction, form validation, session management, etc. CodeIgniter also has great performance and a small learning curve.
4. Yii: Yii is a high-performance PHP development framework suitable for building large and complex web applications. It provides a highly scalable architecture and rich functionality, including database abstraction, caching, form validation, authentication, and more. Yii also has good performance optimization and security.
5. Phalcon: Phalcon is a brand new PHP development framework known for its high-speed execution and low memory consumption. Compared with other frameworks, Phalcon exists as a C extension, providing faster execution speed and lower resource consumption. It also has a complete set of features such as database abstraction, form validation, routing, etc.
6. CakePHP: CakePHP is a popular PHP development framework with a fast and simple development style. It provides a powerful set of tools and components such as ORM (Object Relational Mapping), caching, form validation, routing, etc. CakePHP also has good documentation and an active community.
These are just some commonly used open source PHP development frameworks. Each framework has its unique characteristics and applicable scenarios. When choosing a framework, you can evaluate and compare based on project size, complexity, and personal or team preferences. No matter which framework you choose, you can make web development faster and more efficient by reducing development effort, increasing development speed, and improving application performance.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

常用的php开发框架有Laravel、Symfony、CodeIgniter、Yii、Phalcon、CakePHP和Slim等。详细介绍:1、Laravel是一个优雅的PHP Web应用程序框架,它提供了简单、优雅的语法和丰富的功能,例如路由、ORM、模板引擎等,Laravel有着活跃的社区和完善的文档,被广泛认可为PHP开发中最好的框架之一;2、Symfony等等。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。
