php smooth upgrade

1.既然是平滑升级，是不需要宕机，也不需要停止服务，是不存在关闭网站的说法
2.而升级最后的重启，重启的是PHP加载的配置文件，不影响你当前运行的网站
3.php-fpm是属于FastCgi，一旦启动是在内存中跑的，和你编译升级的过程没有任何关系

## Reason: If "undefined reference to libiconv_open" occurs when installing PHP into the system '" and other error messages, it means that some environment variable values are not captured properly in "./configure". The error occurred when creating "-o sapi/cli/php", and the iconv library parameter to be linked was not given.

The first solution: edit the Makefile around line 77: EXTRA_LIBS = ..... -lcrypt and add -liconv at the end, for example: EXTRA_LIBS = ..... -lcrypt -liconv and then try again Just make.
Second solution:
make ZEND_EXTRA_LIBS='-liconv'
ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/
