MongoDB PHP7扩展安装配置使用教程
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 MongoDBDriverManager("mongodb://localhost:27017");
插入数据
将 name 为"小白教程" 的数据插入到 test 数据库的 json 集合中。
<?php $bulk = new MongoDBDriverBulkWrite;$document = ['_id' => new MongoDBBSONObjectID, 'name' => '小白教程'];$_id= $bulk->insert($document);var_dump($_id);$manager = new MongoDBDriverManager("mongodb://localhost:27017"); $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);$result = $manager->executeBulkWrite('test.json', $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 $manager = new MongoDBDriverManager("mongodb://localhost:27017"); // 插入数据$bulk = new MongoDBDriverBulkWrite;$bulk->insert(['x' => 1, 'name'=>'小白教程', 'url' => '']);$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$query = new MongoDBDriverQuery($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 $bulk = new MongoDBDriverBulkWrite;$bulk->update( ['x' => 2], ['$set' => ['name' => '菜鸟工具', 'url' => 'tool.json.cn']], ['multi' => false, 'upsert' => false]);$manager = new MongoDBDriverManager("mongodb://localhost:27017"); $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);$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 $bulk = new MongoDBDriverBulkWrite;$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 MongoDBDriverManager("mongodb://localhost:27017"); $writeConcern = new MongoDBDriverWriteConcern(MongoDBDriverWriteConcern::MAJORITY, 1000);$result = $manager->executeBulkWrite('test.sites', $bulk, $writeConcern);?>
