mac 怎麼安裝php mongodb?
mac下PHP安裝mongodb的擴充:
phpize路徑為/usr /local/php/bin/phpize。
php-config路徑為 /usr/local/php/bin/php-config。
1.首先下載php的mongodb擴充
從http://pecl.php.net/package/mongodb這個網址下載mongodb的擴充原始碼包（注意：不要從http://pecl.php.net/package/mongo下載，因為這個package已經過期），在命令列執行以下命令：
wget http://pecl.php.net/get/mongodb-1.4.3.tgz
2.解壓縮安裝套件
tar -zxvf mongodb-1.4.3.tgz
3.進入解壓縮目錄，執行phpize，為安裝擴充功能準備環境
cd mongodb-1.4.3 /usr/local/php/bin/phpize
4.安裝編譯mongodb的php擴充
第3步執行完成後，在目前目錄下就產生了configure檔。接下來，使用./configure指令進行安裝設定；然後，使用make && make install進行編譯安裝，指令如下：
./configure --with-php-config=/usr/local/php/bin/php-config make && make install
5. 檢視是否在PHP擴充目錄中已經產生.so擴充檔
php -i | grep extension_dir //查看PHP扩展包存储目录，这里为extension_dir => /usr/local/lib/php/pecl/20160303 => /usr/local/lib/php/pecl/20160303 ls /usr/local/lib/php/pecl/20160303 //查看目录中是否有mongodb.so文件
6.編輯php.ini，在extension區域加入mongodb擴充
extension=mongodb.so
注意：擴充功能的名稱是mongodb.so，不是mongo.so。
7.查看PHP的mongodb擴充模組是否已經成功安裝
php -m | grep mongodb
如果在直接結果中看到mongodb，就表示已經安裝成功。
或著，重新啟動php-fpm，然後執行phpinfo()方法。若看到mongodb的內容，表示安裝成功。
8. 在PHP中使用mongodb擴充
在安裝完成PHP的mongodb的擴充後，在composer.json檔案的require區塊中新增"mongodb/mongodb": "^1.4" 。然後，再透過composer指令載入mongodb PHP版本客戶端的擴充包，指令如下所示：
composer require mongodb/mongodb
結果報瞭如下的錯誤：
Using version ^1.4 for mongodb/mongodb
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- mongodb/mongodb 1.4.2 requires ext-mongodb ^1.5.0 -> the requested PHP extension mongodb has the wrong version (1.4.3) installed.
- mongodb/mongodb 1.4.2 requires ext-mongodb ^1.5.0 -> the requested PHP extension mongodb has the wrong version (1.4.3) installed.
- mongodb/mongodb 1.4.1 requires ext-mongodb ^1.5.0 -> the requested PHP extension mongodb has the wrong version (1.4.3) installed.
- mongodb/mongodb 1.4.0 requires ext-mongodb ^1.5.0 -> the requested PHP extension mongodb has the wrong version (1.4.3) installed.
- Installation request for mongodb/mongodb ^1.4 -> satisfiable by mongodb/mongodb[1.4.0, 1.4.1, 1.4.2].
To enable extensions, verify that they are enabled in your .ini files:
- /usr/local/etc/php/7.1/php.ini
- /usr/local/etc/php/7.1/conf.d/ext-opcache.ini
You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
Installation failed, reverting ./composer.json to its original content.分析發現，是安裝的mongodb擴充版本太低。於是，改為1.5.3版本(mongodb-1.5.3.tgz)，重新操作一遍，再次透過composer指令載入mongodb PHP版本客戶端的擴充包，就好了。詳情如下：
