## 1、下载PHP源代码 首先需要从PHP官网下载PHP7.3.6的源代码，[点击下载]() 下载到自己存放的目录当中   ``` 解压 tar -zxf php-7.3.6.tar.gz 进入目录 cd php-7.3.6 ``` ## 2、安装依赖 ``` sudo apt update sudo apt install gcc sudo apt install make sudo apt install openssl sudo apt install curl sudo apt install libbz2-dev sudo apt install libxml2-dev sudo apt install libjpeg-dev sudo apt install libpng-dev sudo apt install libfreetype6-dev sudo apt install libzip-dev ``` >[danger] 安装好这些依赖，可能还会出现一些依赖不存在的错误，到时候有什么提示错误，百度搜索安装即可 ## 3、配置PHP ``` ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysqli --with-pdo-mysql --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts ``` >[success] +--------------------------------------------------------------------+| License: || This software is subject to the PHP License, available in this || distribution in the file LICENSE.
