想要编译安装PHP首先需要安装对应的编译工具。 Ubuntu上使用如下命令安装编译工具和依赖包：

sudo apt-get install build-essential gcc g++ autoconf libiconv-hook-dev libmcrypt-dev libxml2-dev libmysqlclient-dev libcurl4-openssl-dev libjpeg8-dev libpng12-dev libfreetype6-dev \

wget http://php.net/get/php-5.6.30.tar.gz

tar -zxvf php-5.6.30

cd php-5.6.30
