php 使用 casperjs，解决 权限不足问题

1、安装 phantomjs 1.x

cd /usr/local
wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.8-linux-x86_64.tar.bz2 tar
jxvf phantomjs-1.9.8-linux-x86_64.tar.bz2
mv phantomjs-1.9.8-linux-x86_64 phantomjs

ln -s /usr/local/phantomjs/bin/phantomjs /usr/local/bin/

2、用git安装casperjs

cd /usr/local

git clone git://github.com/casperjs/casperjs.git
ln -s /usr/local/casperjs/bin/casperjs /usr/local/bin/

3、在php中调用casperjs可能需要

putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs");

再推荐个php封装casperjs的库
