1，官方网站:

https://www.php.net/

2,下载

[root@yjweb source]# wget https://www.php.net/distributions/php-7.4.2.tar.gz

说明：在linux上以编译方式安装软件时，多数人都习惯把软件安装到 /usr/local目录下，

我们在生产环境中的习惯使用两个目录:

/usr/local/source    保存源码/rpm安装包

/usr/local/soft         保存安装的软件

之所以这样区分，是为了把当时下载的源码或安装包也保存一份，

一来以后用到时能了解到当时的版本

二来如果需要重新编译时也无需去各软件的官网上去找历史版本

1，解压命令和configure命令

[root@yjweb source]# tar -zxvf php-7.4.2.tar.gz
[root@yjweb source]# cd php-7.4.2/
[root@yjweb php-7.4.2]# ./configure --prefix=/usr/local/soft/php7 --with-curl --with-freetype --enable-gd --with-jpeg --with-gettext --with-iconv-dir=/usr/local --with-kerberos --with-libdir=lib64 --with-libxml --with-mysqli --with-openssl --with-pdo-mysql --with-pdo-sqlite --with-pear --enable-sockets --with-mhash --with-ldap-sasl --with-xmlrpc --with-xsl --with-zlib --enable-fpm --enable-bcmath --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-xml --with-zip --with-config-file-path=/usr/local/soft/php7/etc -with-bz2 --enable-inline-optimization --enable-sysvsem

说明：上面的configure命令的参数是php-7.4.2可用的参数，

一些旧的不可用的参数会在configure时给出提示，

大家不要使用已经废弃的参数，避免安装完成后不能正常使用
