解決辦法：

下載ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz見附件(試了幾下附件沒有上傳成功，大家可把這個文件名放在百度里搜下會有很多)，

解決文件：

ZendGuardLoader-php-5.3-linux-glibc23-x86_64
|-- README.txt
`-- php-5.3.x
    `-- ZendGuardLoader.so

把ZendGuardLoader.so這個文件復制到/usr/local/lib目錄下,(沒有相應的目錄請創建)

然后找到php.ini所對應的配置文件，我的是在/etc/php.ini

在最后一行添加

zend_extension = /usr/local/lib/ZendGuardLoader.so

保存，之后重啟php

/etc/init.d/php-fpm restart

再去試一下就OK了，我的php版本是5.3的喲，你的可能要去找相應的ZendGuardLoader這個版本的文件
