PHP7 Mongdb 擴充套件安裝

    我們使用 pecl 命令來安裝：

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

   執行成功後，會輸出以下結果：

……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"isnotset to php.ini location
 
You should add "extension=mongodb.so" to php.ini

 接下來我們開啟 php.ini 檔案，新增 extension=mongodb.so 配置。

   可以直接執行以下命令來新增。

$ echo "extension=mongodb.so">>`/usr/local/php7/bin/php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`

   注意：以上執行的命令中 php7 的安裝目錄為 /usr/local/php7/，如果你安裝在其他目錄，需要相應修改 pecl 與 php 命令的路徑。

Mongodb 使用

   PHP7 連線 MongoDB 語法如下：

$manager =newMongoDB\Driver\Manager("mongodb://localhost:27017");

插入資料

   將 name 為"自學教程" 的資料插入到 test 資料庫的 runoob 集合中。

<?php
$bulk = new MongoDB\Driver\BulkWrite;
$document = ['_id' => new MongoDB\BSON\ObjectID, 'name' => '菜鳥教程'];

$_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);
?>
 

讀取資料

<?php
$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  

// 插入資料
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->insert(['x' => 1, 'name'=>'baidu', 'url' => 'http://www.baidu.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],
];

// 查詢資料
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('test.sites', $query);

foreach ($cursor as $document) {
    print_r($document);
}
?>

更新資料

<?php
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->update(
    ['x' => 2],
    ['$set' => ['name' => '菜鳥工具', '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);
?>

刪除資料

<?php
$bulk = new MongoDB\Driver\BulkWrite;
$bulk->delete(['x' => 1], ['limit' => 1]);   // limit 為 1 時，刪除第一條匹配資料
$bulk->delete(['x' => 2], ['limit' => 0]);   // limit 為 0 時，刪除所有匹配資料

$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);
?>
