35-三十五、PHP7 MongDB 扩展安装与使用

在前面的章节中我们学习了 MongoDB PHP 扩展使用范例,不过那篇文章只能针对 PHP5 使用,PHP7 以上版本则需要使用其它的 PHP MongoDB 扩展

PHP7 Mongdb 扩展安装

假设我们的 PHP7 安装在 /usr/local/php7 目录

我们可以使用 pecl 命令来安装 PHP MongoDB 扩展


$ /usr/local/php7/bin/pecl install mongodb

执行成功后,会输出以下信息


... Build process completed successfully Installing '/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/mongodb.so' install ok: channel://pecl.php.net/mongodb-1.1.7 configuration option "php_ini" is not set to php.ini location You should add "extension=mongodb.so" to php.ini

然后打开 php.ini 文件添加 extension=mongodb.so 配置

或者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

PHP7 MongoDB 使用范例

PHP7 连接 MongoDB 数据库


<?php /* * filename: main.php * author: 研发军团(www.ycbbs.vip) * Copyright © 2015-2065 www.ycbbs.vip. All rights reserved. */ $driver = new MongoDB\Driver\Manager("mongodb://localhost:27017");

PHP7 MongoDB 插入数据

我们可以使用以下代码将 Python 插入到 ycbbs 数据库的 language 集合中


<?php /* * filename: main.php * author: 研发军团(www.ycbbs.vip) * Copyright © 2015-2065 www.ycbbs.vip. All rights reserved. */ $driver = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $bulk = new MongoDB\Driver\BulkWrite; $document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => 'Python']; $_id= $bulk->insert($document); var_dump($_id); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000); $result = $driver->executeBulkWrite('test.language', $bulk, $writeConcern);

运行以上 PHP7 脚本,输出结果如下


$ php main.php object(MongoDB\BSON\ObjectId)#4 (1) { ["oid"]=> string(24) "59eef1902a2f950ad3720422" }

读取数据

我们先将 PerlPHPRuby 插入到 language 集合中,然后读取迭代出来


<?php /* * filename: main.php * author: 研发军团(www.ycbbs.vip) * Copyright © 2015-2065 www.ycbbs.vip. All rights reserved. */ $driver = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $bulk = new MongoDB\Driver\BulkWrite; $bulk->insert(["name"=> "Perl"]); $bulk->insert(["name"=> "PHP"]); $bulk->insert(["name"=> "Ruby"]); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000); $result = $driver->executeBulkWrite('test.language', $bulk, $writeConcern); $filter = []; $options = [ 'projection' => ['_id' => 0], 'sort' => ['name' => -1], ]; // 查询数据 $query = new MongoDB\Driver\Query($filter, $options); $cursor = $driver->executeQuery('test.language', $query); foreach ($cursor as $document) { print_r($document); }

运行以上 PHP7 脚本,输出结果如下


$ php main.php stdClass Object ( [name] => Ruby ) stdClass Object ( [name] => Python ) stdClass Object ( [name] => Perl ) stdClass Object ( [name] => PHP )

更新数据

我们将 PHP 语言改成 PHP7


<?php /* * filename: main.php * author: 研发军团(www.ycbbs.vip) * Copyright © 2015-2065 www.ycbbs.vip. All rights reserved. */ $driver = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $bulk = new MongoDB\Driver\BulkWrite; $bulk->update( ['name' => 'PHP'], ['$set' => ['name' => 'PHP7']], ['multi' => false, 'upsert' => false] ); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000); $result = $driver->executeBulkWrite('test.language', $bulk, $writeConcern); $filter = []; $options = [ 'projection' => ['_id' => 0], 'sort' => ['name' => -1], ]; // 查询数据 $query = new MongoDB\Driver\Query($filter, $options); $cursor = $driver->executeQuery('test.language', $query); foreach ($cursor as $document) { print_r($document); }

运行以上 PHP7 脚本,输出结果如下


$ php main.php stdClass Object ( [name] => Ruby ) stdClass Object ( [name] => Python ) stdClass Object ( [name] => Perl ) stdClass Object ( [name] => PHP7 )

删除数据

现在我们删除 PHP7 这条数据


<?php /* * filename: main.php * author: 研发军团(www.ycbbs.vip) * Copyright © 2015-2065 www.ycbbs.vip. All rights reserved. */ $driver = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $bulk = new MongoDB\Driver\BulkWrite; $bulk->delete(['name' => 'PHP7'], ['limit' => 0]); // limit 为 0 时,删除所有匹配数据 $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000); $result = $driver->executeBulkWrite('test.language', $bulk, $writeConcern); $filter = []; $options = [ 'projection' => ['_id' => 0], 'sort' => ['name' => -1], ]; // 查询数据 $query = new MongoDB\Driver\Query($filter, $options); $cursor = $driver->executeQuery('test.language', $query); foreach ($cursor as $document) { print_r($document); }

运行以上 PHP7 脚本,输出结果如下


$ php main.php stdClass Object ( [name] => Ruby ) stdClass Object ( [name] => Python ) stdClass Object ( [name] => Perl )
