Same as abovedocker
For development environment, just use the one that comes with PHP 5.4+
<code>php -S localhost:9000 -t /path/to/wwwroot</code>
Write an ssh. .
For local development, you can directly use phpstudy to install it. It can be green, or xampp, or wamp. It is very easy to use.
If it’s WEB, why do you have to reinstall it all the time?
docker
Write a shell script...

Installed and integrated.
Or write it as a shell script as mentioned above, that is, write the installation steps and configuration into a script
You can use XAMPP, but now the better choice is docker
But maybe XAMPP is better to get started

lnmp.org one-click script
<code>sudo apt-get install php5-cli php5-mysql mysql #PHP内置HTTP服务器,用来做快速开发很方便 php -S 127.0.0.1:8080 -t /path/to/wwwroot</code>
vagrant such as laravel homestead

Installing lnmp in Linux environment is actually very simple
You can use docker, vagrant
You can add the warehouse source and install it directly from the command line
You can use a virtual machine
Then install the required environment on the virtual machine. You can still maintain the same development environment after changing your computer. That's what I've done before.
You can buy a mac later and don’t have to think about reinstalling the system. If you change computers, you can use backup and restore.
If it is an Ubuntu0 or Debian system, you can use apt to install
pants’ tutorial: Ubuntu 16.04 quick configuration LNMP (LEMP) environment
If it is a system like Centos that does not have a package manager, as far as I know, the only way to quickly install it is to use AMH without compilation
Of course, if you are not pursuing installation speed, it is still very good to use scripts such as lnmp

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。

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。
