php has frameworks such as Laravel, Symfony, CodeIgniter, Yii, CakePHP, Zend Framework, Phalcon and Slim. 1. Laravel, which provides many useful functions, such as routing, database migration, ORM, etc.; 2. Symfony, which provides a set of tools and components for building high-performance web applications; 3. CodeIgniter, which provides a simple and easy Understand the documentation and tutorials, etc.

PHP is a scripting language widely used in the field of web development. It has a large number of frameworks to choose from to speed up the development process, improve code quality and maintenance efficiency. In this article, we will introduce some common frameworks of PHP.
1. Laravel: Laravel is a popular PHP framework that makes web application development faster and easier through concise and elegant syntax and powerful feature integration. Laravel provides many useful features such as routing, database migration, ORM (Object Relational Mapping), etc.
2. Symfony: Symfony is a stable and reliable PHP framework that provides a set of tools and components for building high-performance web applications. Symfony follows strict design principles and best practices, and is scalable, testable, and maintainable.
3. CodeIgniter: CodeIgniter is a lightweight PHP framework that is widely used to develop fast and efficient web applications. CodeIgniter is small and flexible, helping developers quickly build powerful applications, while also providing a set of easy-to-understand documentation and tutorials.
4. Yii: Yii is a high-performance PHP framework designed for developing large and complex web applications. Yii has rich functions and a powerful caching mechanism, and supports development models such as MVC (Model-View-Controller) and ORM.
5. CakePHP: CakePHP is an excellent PHP development framework that provides everything you need to quickly develop applications. CakePHP supports data verification, caching, database migration and other functions, and adopts the MVC architecture model to make the application structure clear and clear.
6. Zend Framework: Zend Framework is a feature-rich and flexible PHP framework that can be used to build high-quality, scalable and secure web applications. Zend Framework has a large number of components and libraries, providing developers with a wide range of choices and customization capabilities.
7. Phalcon: Phalcon is a high-performance PHP framework known for its speed and low memory consumption. Phalcon is a C extension that offers faster execution and response time compared to other PHP frameworks.
8. Slim: Slim is a simple, lightweight PHP framework suitable for building small web applications and APIs. Slim features clean routing, lightweight containers, and fast HTTP request and response handling.
The above are just a small part of the PHP frameworks, there are many other excellent frameworks to choose from. Choosing a suitable PHP framework depends on project requirements, personal preferences and the skill level of the development team. No matter which framework you choose, you can improve development efficiency, code quality, and maintainability, thereby providing users with an excellent web application experience. .

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字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

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。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

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。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。

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),
