1. Canphp:
Canphp is a Chinese open source PHP framework. The main design concept is to pursue simplicity, reduce the learning cost for PHP beginners, and pursue high efficiency. The template class does not provide other tags, and the source code of PHP is directly applied. , and it has a microkernel design, strong portability, loose coupling and other characteristics, and can be integrated into any of your systems. The integrated http class is quite powerful and the image collection speed is quite fast. Why is this? Because the principle of simulating asynchronous multi-process is applied.
2. CakePHP:
CakePHP is a good choice for both beginners and professional PHP developers. It is designed based on the same principles as Ruby on Rails, with a strong emphasis on rapid development - making it a very good development framework for RAD. Its rapidly growing support system, simplicity, and scalability make CakePHP one of the most popular PHP development frameworks available today.
3. Thinkphp:
ThinkPHP is a lightweight PHP development framework with excellent performance and rich functions. It has many original features and advocates simplicity. The development is based on my development philosophy and can accomplish more with the least code. The function is designed to make WEB application development simpler and faster. Compatibility with PHP4 has been abandoned since version 1.*, so the architecture and implementation of the entire framework can be more flexible and simpler. Version 2.0 is based on the previous one. After a new reconstruction and countless improvements and improvements, it has reached a new stage, which is enough to meet enterprise-level and portal-level development standards. The latest version of the PHP framework developed by Chinese people is version 3.1, and version 3.1.2 will be released in November 2012.
ThinkSNS open source Weibo system is based on the core of Thinkphp.
ThinkSNS is an open source social platform for Thinkers. It adopts PHP+MySQL technology platform, Weibo+application product model, and also has iphone, android client, wap, and 3G version interfaces.
4. FleaPHP:
FleaPHP is a completely domestic framework. It is an application framework developed using PHP (fully supporting PHP4 and PHP5). FleaPHP provides developers with the necessary basic functions and auxiliary components to help developers create applications easily and quickly. The core of the FleaPHP framework is very small, but through flexible configuration, various types of infrastructure can be combined. FleaPHP's excellent customization and expansion capabilities make it truly close to the goal of "meeting various needs from simple applications to enterprise development." Applications developed using the FleaPHP framework can automatically adapt to various operating environments and are compatible with PHP4 and PHP5. Unlike many other frameworks, FleaPHP is a framework that is completely refined during actual development.
The FleaPHP framework is simple, clear, easy to understand and learn, and has complete Chinese documentation and rich sample programs. High configuration, high performance and other advantages make FleaPHP a popular framework.

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。
