1.先下载php8最新源码，并且解压
wget -c https://github.com/php/php-src/archive/refs/tags/php-8.0.8.tar.gz
tar -zxvf php-8.0.8.tar.gz
cd php-src-php-8.0.8/
./buildconf --force
2.安装php需要的依赖库
(ubuntu centos 基本上替换下 前面的apt即可，如果不行找下相对应库的命令安装即可)
sudo apt-get install pkg-config build-essential \
autoconf bison re2c libxml2-dev libsqlite3-dev libcurl4-gnutls-dev \
libjpeg-dev libpng-dev libmcrypt-dev libreadline6-dev libfreetype6-dev \
libtidy-dev libtool valgrind openssl libssl-dev libzip-dev libwebp-dev \
libxpm-dev -y
3.编译
./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \
--enable-rpath \
--enable-re2c-cgoto \
--enable-gcc-global-regs \
--enable-phpdbg \
--with-valgrind \

--enable-bcmath \
--enable-calendar \
--with-curl \
--enable-ftp \

Thank you for using PHP.
如果报错 No package 'oniguruma' found，点击查看处理办法
sudo make -j4
// 加快编译速度可以用下面的
// make -j4
// 使用方法就是在-j后面加一个数字，比如 -j4，意为在编译文件的时候用4个线程进行编译.
sudo make install
