Unless you write a simple small program, a few hundred lines of it, just write it natively.
Slightly more complex projects generally use frameworks, which are faster to write and make less mistakes. (Recommended learning: PHP video tutorial)
php framework is mostly used in China thinkphp, even if it is to support domestic products, you should learn it~~
There are many internationally popular ones like Laravel, CI, YII, ZF, etc.
Companies generally use frameworks for projects, and even develop their own frameworks themselves.
The development of software systems has become very complicated today, especially server-side software, which involves too much knowledge, content, and problems.
Using other people's mature frameworks in some aspects is equivalent to asking others to help you complete some basic work. You only need to concentrate on completing the business logic design of the system
. Moreover, the framework is generally mature and robust, and it can handle many detailed issues of the system, such as transaction processing, security, data flow control and other issues. In addition, frameworks are generally used by many people, so the structure is very good, so the scalability is also very good, and it is constantly upgraded, and you can directly enjoy the benefits of other people's code upgrades.
The biggest benefit of the framework is reuse. The biggest reuse method obtained by object-oriented systems is the framework. A large application system may often be composed of multiple layers of frameworks that cooperate with each other.
Because the framework can reuse code, it becomes very easy to build applications from an existing component library, because the components all use interfaces uniformly defined by the framework, making communication between components simple.
Frameworks can reuse designs. It provides reusable abstract algorithms and high-level designs, can decompose large systems into smaller components, and can describe the internal interfaces between components.
These standard interfaces make it possible to build various systems through assembly based on existing components. As long as it conforms to the interface definition, new components can be inserted into the framework, and component designers can reuse the design of the framework.
The framework can also reuse analysis. If all personnel analyze matters according to the idea of the framework, they can divide it into the same components and adopt similar solutions, so that analysts using the same framework can communicate with each other.

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。

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。

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。

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。

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。
