解决办法：
下载ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz见附件(试了几下附件没有上传成功，大家可把这个文件名放在百度里搜下会有很多)，
解决文件：
ZendGuardLoader-php-5.3-linux-glibc23-x86_64
|-- README.txt
`-- php-5.3.x
`-- ZendGuardLoader.so
把ZendGuardLoader.so这个文件复制到/usr/local/lib目录下,(没有相应的目录请创建)
然后找到php.ini所对应的配置文件，我的是在/etc/php.ini
在最后一行添加
zend_extension = /usr/local/lib/ZendGuardLoader.so
保存，之后重启php
/etc/init.d/php-fpm restart
再去试一下就OK了，我的php版本是5.3的哟，你的可能要去找相应的ZendGuardLoader这个版本的文件
