编译并安装
# make && make install
安装结果摘要，里面有几个主要的安装路径变量
libtool: install: warning: remember to run `libtool --finish /usr/local/src/php-5.3.6/libs'

貌似要运行一次libtool --finish ....，不过我运行后也没什么奇特效果~
更新httpd配置文件以便apache能解析php文件
# vim /etc/httpd/conf/httpd.conf
添加以下内容
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
如果在卸载原有PHP之前没备份php.ini文件，那么可以从PHP编译目录中把 php.ini-production 拷贝到 /etc目录下并改名为 php.ini
# mv /usr/local/src/php-5.3.6/php.ini-production /etc/php.ini
添加或者更新相关设置，比如：
extension_dir = "/usr/local/lib/php/20090626"
# 以下六个模块可根据需要添加
extension = bz2.so
extension = calendar.so
extension = curl.so
extension = mcrypt.so
extension = pdo_sqlite.so
extension = sqlite.so
max_execution_time = 30
max_input_time = 60
memory_limit = 128M
variables_order = "EGPCS"
register_globals = Off
register_long_arrays = Off
post_max_size = 30M
upload_max_filesize = 30M
mbstring.internal_encoding = UTF-8
date.timezone = Asia/Chongqing
测试结果。在 /var/www/html 下面新建一个文件 phpinfo.php ，里面包含内容
Php代码
<?php phpinfo(); ?>重启apache服务
# service httpd restart
然后在浏览器打开 文件查看php配置状况，这里ip地址为服务器地址
