PHP7 MongDB 安装与使用

PHP7 MongDB 安装与使用本文教程只适合在 PHP7 的环境，如果你是 PHP5 环境，你可以参阅 PHP MongDB 安装与使用。PHP7 Mongdb 扩展安装我们使用 pecl 命令来安装：$ /usr/local/php7/bin/pecl install mongodb执行成功后，会输出以下结果：……Build process completed successfullyInstalling '/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/mongodb.so'install ok: channel://pecl.php.net/mongodb-1.1.7configuration option "php_ini" is not set to php.ini locationYou should add "extension=mongodb.so" to php.ini接下来我们打开 php.ini 文件，添加 extension=mongodb.so 配置。可以直接执行以下命令来添加。$ echo "extension=mongodb.so" >> `/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`注意：以上执行的命令中 php7 的安装目录为 /usr/local/php7/，如果你安装在其他目录，需要相应修改 pecl 与 php 命令的路径。Mongodb 使用PHP7 连接 MongoDB 语法如下：$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");插入数据将 name 为"k88.net" 的数据插入到 test 数据库的 k88 集合中。<?php$bulk = new MongoDB\Driver\BulkWrite;$document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => 'k88.net'];$_id= $bulk->insert($document);var_dump($_id);$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);$result = $manager->executeBulkWrite('test.k88', $bulk, $writeConcern);?>读取数据这里我们将三个网址数据插入到 test 数据库的 sites 集合，并读取迭代出来：<?php$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); // 插入数据$bulk = new MongoDB\Driver\BulkWrite;$bulk->insert(['x' => 1, 'name'=>'k88.net', 'url' => 'http://www.k88.net']);$bulk->insert(['x' => 2, 'name'=>'Google', 'url' => 'http://www.google.com']);$bulk->insert(['x' => 3, 'name'=>'taobao', 'url' => 'http://www.taobao.com']);$manager->executeBulkWrite('test.sites', $bulk);$filter = ['x' => ['$gt' => 1]];$options = [ 'projection' => ['_id' => 0], 'sort' => ['x' => -1],];// 查询数据$query = new MongoDB\Driver\Query($filter, $options);$cursor = $manager->executeQuery('test.sites', $query);foreach ($cursor as $document) { print_r($document);}?>输出结果为：stdClass Object( [x] => 3 [name] => taobao [url] => http://www.taobao.com)stdClass Object( [x] => 2 [name] => Google [url] => http://www.google.com)更新数据接下来我们将更新 test 数据库 sites 集合中 x 为 2 的数据：<?php$bulk = new MongoDB\Driver\BulkWrite;$bulk->update( ['x' => 2], ['$set' => ['name' => '菜鸟工具', 'url' => 'tool.k88.net']], ['multi' => false, 'upsert' => false]);$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);$result = $manager->executeBulkWrite('test.sites', $bulk, $writeConcern);?>接下来我们使用 "db.sites.find()" 命令查看数据的变化，x 为 2 的数据已经变成了菜鸟工具：删除数据以下实例删除了 x 为 1 和 x 为 2的数据，注意 limit 参数的区别：<?php$bulk = new MongoDB\Driver\BulkWrite;$bulk->delete(['x' => 1], ['limit' => 1]); // limit 为 1 时，删除第一条匹配数据$bulk->delete(['x' => 2], ['limit' => 0]); // limit 为 0 时，删除所有匹配数据$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);$result = $manager->executeBulkWrite('test.sites', $bulk, $writeConcern);?>更多使用方法请参考：http://php.net/manual/en/book.mongodb.php。
