PHP简介：
PHP是一种创建动态交互性站点的强有力的服务器端脚本语言。PHP是目前动态网页开发中使用最为广泛的语言之一。PHP能运行在包括Windows、Linux等在内的绝大多数操作系统环境中。
PHP是免费的，并且使用非常广泛。同时，对于像微软 ASP 这样的竞争者来说，PHP 无疑是另一种高效率的选项。

给大家介绍下CentOs7下如何通过编译去安装php7.1.5，教程亲测可行。
1、下载php-7.1.5软件包
下载地址：
[root@ localhost ~]# wget -c
2、解压php7
[root@localhost ~]# tar zxf php-7.1.5.tar.gz
3、移动解压之后的文件夹到/usr/local/
[root@localhost ~]# mv php-7.1.5 /usr/local/php
4、进入php目录
[root@localhost ~]# cd /usr/local/php
5、安装依赖包
[root@localhost php]# yum –y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
6、编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致），嫌麻烦的可以从这一步起参考PHP官方安装说明： （极简安装）
[root@localhost php]# ./configure \
–prefix=/usr/local/php \
–with-config-file-path=/etc \
–enable-fpm \
–with-fpm-user=www \
–with-fpm-group=www \
–enable-inline-optimization \
–disable-debug \
–disable-rpath \
–enable-shared \
–enable-soap \
–with-libxml-dir \
–with-xmlrpc \
–with-openssl \
–with-mcrypt \
–with-mhash \
–with-pcre-regex \
–with-sqlite3 \
–with-zlib \
–enable-bcmath \
–with-iconv \
–with-bz2 \
–enable-calendar \
–with-curl \
–with-cdb \
–enable-dom \
–enable-exif \
–enable-fileinfo \
–enable-filter \
–with-pcre-dir \
–enable-ftp \
–with-gd \
–with-openssl-dir \
–with-jpeg-dir \
–with-png-dir \
–with-zlib-dir \
–with-freetype-dir \
–enable-gd-native-ttf \
–enable-gd-jis-conv \
–with-gettext \
–with-gmp \
–with-mhash \
–enable-json \
–enable-mbstring \
–enable-mbregex \
–enable-mbregex-backtrack \
–with-libmbfl \
–with-onig \
–enable-pdo \
–with-mysqli=mysqlnd \
–with-pdo-mysql=mysqlnd \
–with-zlib-dir \
–with-pdo-sqlite \
–with-readline \
–enable-session \
–enable-shmop \
–enable-simplexml \
–enable-sockets \
–enable-sysvmsg \
–enable-sysvsem \
–enable-sysvshm \
–enable-wddx \
–with-libxml-dir \
–with-xsl \
–enable-zip \
–enable-mysqlnd-compression-support \
–with-pear \
–enable-opcache
7、正式安装
[root@localhost php]# make && make install
8、配置 php-fpm
[root@localhost php]# cp php.ini-production /etc/php.ini
[root@localhost php]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@localhost php]# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
[root@localhost php]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php]# chmod +x /etc/init.d/php-fpm
9、创建www用户，启动php-fpm
[root@localhost php]# useradd www
[root@localhost php]# /etc/init.d/php-fpm start
至此就已经安装好php7.1.5了，希望可以帮助到大家。如需转载请注明出处。
