2.下载编译安装php 5.3.6：

http://php.net/downloads.php

yum install libxml2 libxml2-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel libmcrypt libmcrypt-devel libtool-ltdl-devel
tar -jxvf php-5.3.6.tar.bz2
cd php-5.3.6
./configure --prefix=/opt/php -with-apxs2=/opt/httpd/bin/apxs --with-curl --with-mcrypt --enable-mbstring --with-iconv --with-gd -with-jpeg-dir=/usr/local/lib --enable-pdo --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --with-mysql=mysqlnd
make
make install
cp php.ini-development /opt/php/lib/php.ini
ln -s /opt/php/bin/php /usr/bin/php
vi /opt/php/lib/php.ini

把include_path前面的分号删除，改成include_path = "/opt/php/lib/php"
sudo vi /opt/httpd/conf/httpd.conf
在最下面加入一行AddHandler application/x-httpd-php .php
sudo /opt/httpd/bin/httpd -k restart
sudo vi /opt/httpd/htdocs/phpinfo.php

phpinfo.php的内容如下：

<?php
phpinfo();
?>

安装完php，重启apache，用浏览器访问http://localhost/phpinfo.php，能正常显示说明php装好了。

查看php版本： php -v
