PHP7 pecl 安裝 mongodb擴展 和 PHPLIB

安裝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
//否則會報錯PHP Parse error: syntax error, unexpected //'new' (T_NEW) in /usr/share/pear/PEAR/Frontend.php on //line 91

安裝擴展

$ pecl install mongodb

And if I try to install mongodb for example, I'll get the same warnings as before with an extra "XML Extension not found" at the end.

I compared the "/usr/bin/pecl" with one from ubuntu and the only difference is the "-n" 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="On" $INCDIR/peclcmd.php "$@"

-n meaning: "No configuration (ini) files will be used"
If not using conf, xml won't be loaded, so I'm pretty sure the "-n" should be removed.

I tested after removing it, and got no warning or anything and was able to install my extension.

以上問題的解決方式：
vi /usr/bin/pecl
remove -n para
刪除 -n 參數

安裝完畢后，添加庫到php.ini

extension=mongodb.so

安裝 PHPLIB

http://php.net/manual/zh/mongodb.tutorial.library.php
https://getcomposer.org/download/
安裝完畢后，安裝 PHP Library for MongoDB (PHPLIB)
$ composer require mongodb/mongodb``<br/>最新版本的命令是：<br/>$ composer.phar require mongodb/mongodb`

一切正確后，在當前目錄下，生成：vendor目錄，OK
