Windows/Linux获取和安装PHP PEAR

前言

引用一句

PEAR is the PHP Extension and Application Repository.

详细太多不再展开,

获取和安装PEAR

因为生产环境使用Linux的比较多,先说说Linux下的实现

Linux

根据官网的指引:

如果使用Unix / Linux / BSD发行商提供的PHP版本,则可能需要手动安装PEAR。在这种情况下,用户应查阅相应发行版的文档。

但其实我为了图省事,就是使用的软件源的PHP,使用PEAR官方方案安装没有问题

其实非常简单,就两条指令:

wget http://pear.php.net/go-pear.phar
php go-pear.phar

当然,在此之前您可能需要提前安装好wget,

同时将php所在目录放入path中或使用软连接建立php程序的软连接到path目录中,一般来说安装好php会自动执行这一步操作

 

Windows

直接运行php根目录下的go-pear.bat即可

当然了你也可以选择和linux类似的安装方式

手动下载文件

在命令提示符中执行

php go-pear.phar

安装程序将询问您一些问题,然后将PEAR软件包管理器安装在您在安装过程中指定的路径中。

最后,根据官方指引,您必须将该安装路径添加到您的 PATH环境中。

如果不想手动操作,可以运行PEAR_ENV.reg,该文件在安装PEAR后,在PHP根目录中可以找到。

之后就可以通过在Windows命令提示符中运行命令来访问PEAR软件包管理器。

 

虚拟主机环境

当然了有一些用户使用虚拟主机服务,无法访问shell或者变更php配置

可以使用以下方案:

访问该网页并将其内容保存为go-pear.php文件,将他上传到服务器某个目录,例如PEAR目录下

然后访问它

# The PEAR installation wizard, both webbased or command line.
#
# Webbased installation:
# 1) Download this file and save it as go-pear.php
# 2) Put go-pear.php on your webserver, where you would put your website
# 3) Open http://yourdomain.example.org/go-pear.php in your browser
# 4) Follow the instructions, done!
#
# Command-line installation (for advanced users):
# 1) Download this file and save it as go-pear.php
# 2) Open a terminal/command prompt and type: php -q go-pear.php
# 3) Follow the instructions, done!
#
# Notes:
# * Get the latest go-pear version from http://pear.php.net/go-pear
# * This installer requires PHP 4.3.0 or newer.
# * On windows, the PHP CLI binary is php.exe, don't forget the -q option if using the CGI binary.
# * The default for the command-line installation is a system-wide configuration file,  For a local install use: php -q go-pear.php local

/**
 * go-pear is the online PEAR installer: just download it and run it
