PHP7 pecl 安装 mongodb扩展 和 PHPLIB

高峰之巅

安装PECL
　　//php版本 > 7
　　

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

　　//php版本 < 7
　　$ yum install php-pear
　　//否则会报错PHP Parse error:  syntax error, unexpected //'new' (T_NEW) in /usr/share/pear/PEAR/Frontend.php on //line 91

安装扩展
　　$ pecl install mongodb
　　And if I try to install mongodb for example, I'll get the same warnings as before with an extra &quot;XML Extension not found&quot; at the end.
　　I compared the &quot;/usr/bin/pecl&quot; with one from ubuntu and the only difference is the &quot;-n&quot; in the exec line :
　　alpine:
　　exec $PHP -C -n -q $INCARG -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv=&quot;On&quot; $INCDIR/peclcmd.php &quot;$@&quot;
　　-n meaning: &quot;No configuration (ini) files will be used&quot;
　　If not using conf, xml won't be loaded, so I'm pretty sure the &quot;-n&quot; should be removed.
　　I tested after removing it, and got no warning or anything and was able to install my extension.
　　sumery:  vi /usr/bin/pecl  remove -n para
　　安装完毕后，添加库到php.ini
　　

　　
extension=mongodb.so
　　

安装 PHPLIB
　　http://php.net/manual/zh/mongodb.tutorial.library.php
　　https://getcomposer.org/download/
　　安装完毕后，安装 PHP Library for MongoDB (PHPLIB)
　　$ composer require mongodb/mongodb``最新版本的命令是：$ composer.phar require mongodb/mongodb`
　　一切正确后，在当前目录下，生成：vendor目录，OK
