XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduce server load.

Download xcahce:

cd /opt
wget tar -zxvf xcache-2.0.1.tar.gz
cd xcache-2.0.1

Use yum to install the PHP compile tools, if you can have installed before, skip this step

yum -y install php-devel yum install -y gcc make

# wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-i386.tar.gz #32位
# wget http://downloads.zend.com/guard/5.5.0/ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz #64位

2、安装Zend Guard

# mkdir /usr/zend #建立Zend Guard安装目录
# tar xvfz ZendGuardLoader-php-5.3-linux-glibc23-i386.tar.gz #解压安装文件
# cp ZendGuardLoader-php-5.3-linux-glibc23-i386/php-5.3.x/ZendGuardLoader.so /usr/zend/ #拷贝文件到安装目录
# rm -rf /home/ZendGuardLoader-php-5.3-linux-glibc23-i386* #删除安装包

引言：

php程序代码被加密过后，必须安装解密软件Zend Optimizer才能进行使用，比如Shopex等php程序，下面我们安装Zend Optimizer 3.3.9（针对php5.2,X之前的版本,php5.3.X需要安装Zend Guard），操作如下：

1、下载Zend optimizer</span>

cd /home
wget http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz #32位
wget http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz #64位

When I try to use vim to code, I found it’s lack of auto completing. Well, I got a solution for that. Please consolt the below information for tails.

Installation:

1. Download the function list file : http://cvs.php.net/viewvc.cgi/phpdoc/funclist.txt

2. Copy function list file to installation path of vim.

3. Add the following code to the end of vimrc:

    "You can obtain the completion dictionary file from:
    "http://cvs.php.net/viewvc.cgi/phpdoc/funclist.txt
    set dictionary-=$VIM/funclist.txt dictionary+=$VIM/funclist.txt
   
    "Use the dictionary completion
    set complete-=k complete+=k
   
    "Auto completion using the TAB key
    "This function determines, wether we are on
    "the start of the line text(then tab indents)
    "or if we want to try auto completion
    function! InsertTabWrapper()
    let col=col(‘.’)-1
    if !col || getline(‘.’)[col–1] !~ ‘k’
    return “<TAB>”
    else
    return “<C-N>”
    endif
    endfunction
   
    "Remap the tab key to select action with InsertTabWrapper
    inoremap <TAB> <C-R>=InsertTabWrapper()<CR>
   

And pay attention on $VIM,that’s your vim’s config directory.
