This tutorial is only suitable for PHP7 environment. If you are in PHP5 environment, you can refer to the PHP MongDB 安装与使用 . We use the pecl command to install: When the execution is successful, the following results are output: Next we open the php.ini file and add extension=mongodb.so Configuration. You can add it by executing the following command directly. 注意： The php7 installation directory in the above command is / usr/local/php7/,. If you install it in another directory, you need to modify the path of the pecl and php commands accordingly. The PHP7 connection MongoDB syntax is as follows: Insert the data whose name is a “rookie tutorial” into the runoob collection of the test database. Here we insert the data of the three URLs into the sites collection of the test database, and read and iterate them out: The output is as follows: Next we will update the data with x 2 in the test database sites collection: Next, we use the “db.sites.find ()” command to see the changes in the data, and the data with x = 2 has become a rookie tool: The following example deletes the data with x 1 and x 2, and notes the difference between the limit parameters: For more information on how to use it, please see http://php.net/manual/en/book.mongodb.php . 3.30.1. PHP7 Mongdb extension installation ¶
$ /usr/local/php7/bin/pecl install mongodb
……
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
$ echo "extension=mongodb.so" >> `/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
3.30.2. Mongodb usage ¶
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
Insert data ¶
<?php
$bulk = new MongoDB\Driver\BulkWrite;
$document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => '菜鸟教程'];
$_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.runoob', $bulk, $writeConcern);
?>
Read data ¶
<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
// 插入数据
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1, 'name'=>'菜鸟教程', 'url' => 'http://www.runoob.com']);
$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);
}
?>
stdClass Object
(
[x] => 3
[name] => taobao
[url] => http://www.taobao.com
)
stdClass Object
(
[x] => 2
[name] => Google
[url] => http://www.google.com
)
Update data ¶
<?php
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update(
['x' => 2],
['$set' => ['name' => '菜鸟工具', 'url' => 'tool.runoob.com']],
['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);
?>
Delete data ¶
<?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);
?>
